Denver resident since 2005, I have tried numerous locally owned gyms and classes. I am truly loving the simplicity, energy and effectiveness of SweatDen. Great space, team and clientele. Highly recommend!
I found Sweat Den during the uncertain times of COVID and it quickly became my go-to for daily workouts. Since then, I've never looked back. Each class is carefully planned, delivering a unique and effective workout every time I hit play. Kelsey and Ross infuse each class with their expertise, positivity and wit. What sets Sweat Den apart is their dedication to their community. While I love my virtual workouts, I can't wait to experience the energy of an in-person class. If you're considering joining Sweat Den, don't hesitate – you won't regret it.
I’ve been a Sweat Den member since the pandemic and started working out from home virtually! This was the best thing to happen to me during this time!! It changed me physically and mentally. Kelsey and Ross are two of the most motivating individuals I’ve met in the industry. They are both the best at what they do! I can’t say enough good things about them and what they have created. I’ve recommended to several friends who agree. Highly recommended. Thank you Sweat Den!
THE BEST WORKOUT in Denver. . . every single time! Great energy, knowledge and results!
I've been using Sweat Den's online platform for the past 2 years on and off, and the experience goes beyond logging in and participating on-demand workouts.
I wish I still lived in Denver so I could be a part of their in-person studio; they bring a contagious sort of magic into their workouts and programming that is hard to find anywhere else!
The Sweat Den team personally responds to questions via email about specific modifications (fertility, IVF, and pregnancy) and provides additional resources like nutrition recommendations and education on the "whys" of the training methodologies that they employ in their classes. I truly feel like they embody the "each day is a bonus" mantra that they often reference in their on-demand videos.
I've been an on-demand member since 2022. I've tried countless online classes and programs and none of them compared to Sweat Den! Ross and Kelsey push me to be the best version of myself and they’ve changed my life for the better! Sweat Den is so much for than just a killer workout, it’s a lifestyle, and the daily lessons it teaches me is immeasurable. Do yourself a favor and try Sweat Den, you won't be disappointed!
I joined Sweat Den this year after a fitness studio that I worked at had closed down. Fitness was my way to not only make me physically feel better but also mentally. I lost my way for a little bit until I stumbled into the Den. Not only did I love the workouts but Kelsey, Ross, and their team went out of their way to get to know me and my story and I immediately felt at home. Not only has my body composition completely changed from their programmed workouts but my mindset has completely shifted for the better (and I am in graduate school so sometimes it can be tough but I know at the end of the day, Sweat Den is exactly where I want to be after a rough day). All this to say I couldn't be more grateful I walked into the Den. Sweat Den made me fall in love with fitness and wellness all over again. Nothing beats the community of people I am surrounded by, the workouts, and the team. I highly recommend checking them out if you haven't yet! You won't regret it!!
Sweat Den is the best! I became a member a few months ago and have nothing but positive things to say. Exercise has always been important to me, but finding the time for effective and efficient workouts had become a challenge. Sweat Den is what I was missing! The instructors, workouts, and members simply rock! (Not to mention the on demand content is amazing, too!)
The energy, the people, the way I feel after leaving this place is all that needs to be said. Sweat den leaving us all in a better place because who wants to be average~
I started the Sweat Den program about a year after having my first baby. I had been going to pilates, but I wasn't consistent. I was looking for a program that aligned to my busy schedule while also helping me to achieve a stronger, toned body. Sweat Den was it for me. Kelsey and Ross know all about the body, they create programs that are motivating and entertaining! Thanks to them my body was in the best shape it's ever been in (even before having a baby!), I was consistent with my workouts and I was actually lifting weights, which I had never done before. I also love that they're local.
Sweat Den has my heart, and I’m a proud founding member as of December 2023. After ten years of bouncing around Denver's fitness scene, the trendy but repetitive workouts left me burnt out, especially as a mom navigating my postpartum body.
Sweat Den is different. Every detail, from the meticulously timed and stacked exercises to the mirror placement, is 100% intentional. It's a testament to the brilliant minds of Kelsey and Ross. Their program and class formats cycle through different phases, keeping workouts fresh and challenging. You can tell they've poured their hearts into this.
Every exercise has at least two modified versions, making Sweat Den accessible for every BODY and fitness level. The instructors genuinely care about each member, taking the time to learn your name and check in, and build you up throughout class. You'll also find yourself sweating alongside some truly amazing humans – from fellow parents to local business owners and other professionals. It's a humbling reminder that everyone is on their own fitness journey, and we're all in it together at Sweat Den.
TLDR: Sweat Den has transformed how I feel. I'm stronger, more capable, and truly feel like I belong to something bigger than myself. If you're looking for a workout that pushes you, supports you, and feels like more than just exercise, Sweat Den is it.
I have been training with Kelsey and Ross on their online platform for most of the last 4 years. After years of participating in competitive sports where we didn’t focus a ton on lifting (not great…), I was desperate for a training program that taught me proper form, ultimately protecting me from injury. As a result of joining Sweat Den, I’ve developed more strength in a safe and strategic way. I’m so grateful to Kelsie and Ross for their expertise and guidance. I think lots of people can benefit from their workouts and overall approach to tackling each day!
This is by far the best studio in Denver! Gorgeous studio with the best community of like minded individuals getting after shaping their mind, body and soul. Kelsey and Ross are the most welcoming owners who thoughtfully curate every single workout. Can not recommend this place enough 10/10
Where do I begin...
Hands down the best and kindest trainers I've ever had the pleasure of working out with. Their investment in everyone's fitness journey is obvious and genuine. The workouts are consistently challenging, and there is a format for everyone's preferences, though rotating through them all weekly keeps my interest, and I am able to balance all aspects of upper body, lower body and core. Sweat Den is a community that is encouraging and kind, not competitive and intimidating. But I think the thing I like most about what they have built - they focus on fitness, but also on health and wellness. They encourage you to take what you need to ensure you are your best self, including rest, breathwork, nutrition, mental health, appreciation for the body and how lucky we are to be able to move.
12/10 would recommend trying a class, or 5!
During the peak of the pandemic, my family and I embarked on a transformative journey with the Sweat Den. With the closure of schools and a rigorous work schedule that stretched from 7 am until 11 pm, our physical and psychological well-being was severely tested. Like countless families across the globe, we were faced with tremendous challenges that seemed insurmountable. However, amidst the chaos and uncertainty that engulfed us, Ross and Kelsey stood tall as beacons of hope and resilience.
Their unwavering commitment to promoting physical wellness and psychological first aid was nothing short of revolutionary. They offered complimentary online classes that not only helped me minimize trauma but also provided an avenue of creative expression for my kids. Their online community and platform became a sanctuary where we could play and move to the music, fostering a sense of connectedness that we desperately needed.
Through their selfless efforts, Ross and Kelsey made an indelible impact on the global community at a time when the world shut down, and people needed it most. Over the years, Sweat Den has grown alongside our family, providing us with constant support and nourishment. As we continue on our journey of recovery and healing from the stresses of everyday life as professionals and parents, Sweat Den remains a steadfast source of inspiration.
We believe in the power of Kelsey and Ross's hearts, which long to serve and grow in the community through wellness. Their compassionate leadership and unwavering dedication to promoting physical and psychological well-being have transformed our lives in ways that are impossible to quantify. For that, we are eternally grateful.
I joined Sweat Den in October 2023 when their new location opened & have been completely blown away by their studio. The instructors, programming, community - 10/10.
I honestly don’t feel like I have adequate words to describe how impactful this place has been for me. Since its flagship studio opening in October, I have seen the most positive changes to my body, mental health, and overall resiliency both physically and emotionally. I have never seen my body respond so quickly and drastically to programming before. And while I will always keep coming back for the workout, it’s community of instructors and members that have made the difference in my experience. This is one of the few spaces I feel like I can show up exactly as I am and walk out feeling stronger, empowered, and supported. Like I told one of the founders recently, I don’t want to live in a city where Sweat Den doesn’t exist. This place is life changing. Dramatic? Maybe. Accurate? 100%.
Truly the best founders, instructors, programming, values, energy, members, and space.
By far the best workouts I have ever done. So thoughtfully constructed and taught. Kelsey and Ross have built such an amazing, inclusive community. They are incredibly supportive and motivating and lead by example. All of the instructors are the best at what they do. I feel stronger and more focused after every class. I am so grateful to be part of the Sweat Den community!
SweatDEN is an awesome fitness community! Everyone on their team makes you feel welcome and inspired and the workouts are fire!
there’s a reason sweat den has the reputation it does! the community is great, workouts are perfectly programmed, and you leave with a sense of gratitude to start the day. Getting to focus on yourself in the space Kelsey and Ross and the team have created is incredible.
Sweat Den has become such an important staple in my life. Not only do they offer well rounded classes that challenge you but are also fun, but the community that they have created is amazing! I have made many friends in my different classes and love to cheer each other on as we hit each milestone. No other group fitness offers the programming they do and it can't be beat. Forever grateful they opened when they did!
I have belonged to boutique fitness studios for over ten years but nothing compares to Sweat Den. The workout, the community, the joy, the push, everything about it makes you want to show up every week. It pushes you but you want to be pushed. I had two spinal surgeries and couldn't lift 3 lbs in October. I'm now lifting 25 lbs and have zero back pain for the first time in 4 years. That speaks for itself. Come try it - you won't regret it!!
Seriously just go and join! I love that SD is a real community, the classes are so hard but a freaking blast, the music is always on point and the vibes are high. I had a hard time finding a gym where I would not only like the workout, but actually want to go regularly. The different formats keep the workouts fresh and the instructors are very attentive to form and ensuring people don’t injure themselves. Love this gym and the way they bring people together!
Absolutely LOVED this workout. So challenging but fun. Wendy is the best and kicks your booty in the best way possible!
Even from afar every workout has been simply amazing. Every time I turned on the workout I felt like I was right there or they were talking directly to me when I wanted to give up or give in. Ross and Kelsey do an amazing job at building and creating this community to empower and push further than most would at home!
Every moment with Kelsey and Ross and the entire Sweat Den crew is a challenge and a blessing. The variety of workouts challenge you in the most amazing ways and they always have so many modifications for all levels and abilities. Kelsey and Ross are the real deal with so much knowledge and experience while still being completely down to earth and genuinely caring about their members and community. Whether you are in the Den or joining virtually, you will not regret the time you spend with them…and your body will thank you for it!


I have known and been working out with Kelsey and Ross for just shy of a decade. They are MY FAVORITE! Positive encouragement through challenging workouts. Love these two.
The best of the best. Their knowledge of and passion for fitness, health, nutrition, and optimizing your days is contagious and infectious. Their programs are challenging, efficient, and fun. No matter where you are or how much time you have, there's a Sweat Den workout for you. Masters of their craft!
5 stars is truly not enough!!! I've tried multiple workout platforms over the years and nothing really stuck long-term. After doing some of Kelsey's iFit running series, I came across the Sweat Den on-demand and was absolutely hooked from day 1. Working out used to feel like a chore and I did it just to check it off the list; now, I honestly can't wait to work out and look forward to it every day!! The series are so well structured and I've noticed such a huge difference in my physical and mental well being. Kelsey and Ross are so encouraging and fun - it feels like I'm working out with friends :) Cannot say enough good things about it!!!
5 stars isn’t enough to describe how amazing Sweat Den is for the body, mind and soul. Kelsey and Ross create such a unique environment and community that can’t be found anywhere else! They inspire strength, mobility and above the mindset that anything can be achieved. My life wouldn’t be the same without the Den.
I swam competitively in college and missed having a consistent challenging program. I appreciate the variety and thoughtfulness behind the workouts. There are a lot of programs out there, but you really get quality with Sweat Den. Post two babies now it has given me the confidence and strength to get back into triathlons.
I have been training online with Sweat Den since 2021, after working out with Kelsey’s running and strength programs on iFit . It truly is the best online community and platform I have known. Kelsey and Ross are engaging, fully knowledgeable and know just how to motivate you to become the best you can be physically and spiritually. The thoughtfully tailored strength programs, live classes and immense video library (strength, tempo, sweat, sculpt, mobility, and much more) make it so easy to get my workout done at any time I need, in the comfort of my home. Kelsey and Ross encourage their community to interact amongst ourselves, making friends, encouraging and helping one another to strive for our best. Thanks Sweat Den!
Sweat Den is the absolute best! The workouts are incredible, Ross and Kelsey are so inspiring and their workouts have helped me to be the strongest version of myself! 10/10 recommend!!
I can’t say enough about Sweat Den! This community is built on so much then just a workout. Kels and Ross think about you as a whole!! They think about your mind, body and soul! I am a Sweat Den member for life!
I feel fortunate to have experienced Sweat Den in both an in-person training environment and virtual environment. The energy, vibe, workout and coaching are exceptional to say the least. I strongly recommend this business to anyone and everyone for more reasons than I have time to list!
Such a great gym and the best trainers / staff! 10/10 recommend checking this place out 🤗
I’ve been training with Kelsey and Ross nearly since the start of Sweat Den, both in person and the online platform, and I can say there’s no better workout or community. The energy that Kelsey and Ross bring to every workout is so positive, motivating, and leaves me feeling so encouraged. They do a great job at pairing challenging workouts with mindfulness, allowing both body and mind to become stronger and more present.
I started with Sweat Den early on during the pandemic. I had just had a baby and not only did SweatDen get me moving again, but Kelsey and Ross made me smile and laugh while working out. The best part was how much I built strength not just physically but emotionally and mentally! The community is a special, unique one and I am honored to be a part of it.
Ross and Kelsey rock! I am so happy I found them almost a year ago now! They know their stuff! They are fun! They are inspirational! They are motivating! And, above all, their positivity wraps it all up like a pretty little bow! Do yourself a favor and sign up now!!
I've never liked instructors or classes before I found Sweat Den. Kelsey and Ross create a down-to-earth, no pressure atmosphere yet you always feel so encouraged and energized by them. The workouts are addicting and the results are real.
I started Sweat Den this year to focus on building muscles after having two babies in 18 months. I love the online platform and the ability to follow a thoughtfully designed strength training program that lets you progress week to week. Kelsey and Ross are so motivating in their videos, it actually makes me want to stick with the routine. I just wish I lived in Denver so I could join their soon to be brick and mortar gym!
I started doing Sweat Den in 2020 and have been hooked ever since - Kelsey and Ross are the perfect duo to encourage you, push you and keep you accountable. The programs and different workout formats have helped me achieve so many fitness goals and I feel stronger than ever (I keep having to buy new weights!). So thankful I found this community, it’s truly become a staple in my routine and a key to overall well-being.
I've been training with Sweat Den roughly 5 years now. Both in the Den and online through their virtual platform. There is nothing like the energy that Kelsey and Ross bring to the table. Every time i would leave training sessions I couldn't believe how far I was able to push my body and how great I felt mentally. I relocated to Georgia, but continue to train with them virtually. Their programs have been a staple getting me wedding ready, through pregnancy, and now post-partum. No matter the phase of life you are in Sweat Den is it. LOVE LOVE LOVE!!!
Wish I could give more than 5 stars. Sweat Den is the best - it has gotten me into the best shape I've ever been. But more than that, it has made me love to work out - I look forward to my workout each day. Kelsey and Ross are so positive, they keep me motivated in the gym but also inspired outside of the gym to be my best self. I am so thankful for Sweat Den!
I have been training at Sweat Den for 3.5 years and it has absolutely transformed my physical and mental health. Kelsey and Ross are incredibly knowledgeable fitness professionals who truly pour so much time and energy into their platform and community. They offer a huge variety of class formats with modifications and variations in every exercise to suit each individual's fitness level - over my years of training with them I used their programs through my entire pregnancy as well as postpartum and onwards. I cannot recommend their studio enough!
I've been training with Kelsey and Ross since 2017 and haven't looked back! Both in studio and at home, they bring knowledge and energy that is unmatched. They offer a variety of thoughtfully programmed workouts- all just as challenging as the next. Don't sleep on Sweat Den! They are the best of the best!
Kelsey and Ross are amazing! I had struggled for years to get back in shape and the Sweat Den programs are what finally got me there. They are fun, engaging and as challenging as you want to make them.
I was first exposed to Kelsey from one of her iFIT running programs where she enthusiastically coached me back into running. However, what really made the difference was adding the Sweat Den programs to the cardio. Not only did I lose pounds but I lost inches and am in the best overall conditioning of my life!
Everyone needs to know about Sweat Den. I joined in 2020 when I was pregnant for the first time, and was able to do every workout during my pregnancy. Kelsey and Ross provide modifications to meet you wherever you are in your fitness journey, making the workouts accessible for everybody. I am now on my third pregnancy, and can say that Sweat Den is the gold standard of workout platforms.
When I was cleared to workout postpartum, I didn't feel like I was starting over. I had gotten stronger by following the Sweat Den programs and, with a lot of modifications, was able to jump back into my routine.
The virtual/on demand workouts have been a lifesaver during this phase of life. As a busy mom of young kids, my schedule is unpredictable. Being able to squeeze in a 30 minute workout at home is an invaluable piece of maintaining my sanity.
Finally, the workouts pack a serious punch. 30 minutes or "low impact" does not mean easy. They are HARD. It is truly like having a personal trainer in your home. Kelsey and Ross are extremely knowledgable in anatomy and the process of building and maintaining lean muscle. So not only are the workouts safe, but they are designed to push you to get stronger. I have learned so much about building muscle just from listening to them during the workouts. They always say that "we are the lucky ones", so if you're able to workout, you should take advantage of a Sweat Den class ASAP!
Sweat Den is a game changer for sure! If you’re looking for challenging workouts of all varieties, trying to get back into a fitness routine, or brand new and looking for guidance…
Kelsey and Ross know how to bring it and have built an amazing community. Give it a month and tell me you’re not hooked- I dare you!
Sweat Den is the best! The workouts are for all levels and the energy and banter Kelsey and Ross give off is infectious. And when you’re convinced you can’t go anymore, you hear the best words “last set, best set” and you have to power through because, why not?! The work outs range from 20 minutes to 45 minutes, so you can make it fit into your day. And with Swear Den, it isn’t about the quantity of time, just the quality of the workout. Kelsey and Ross are not only amazing and inspiring, but they are so down to earth and understand real life. Not only are they the best, but the entire Sweat Den community is absolutely amazing!
Sweat Den has been a complete game-changer for my workout routine — I feel stronger than I ever have, both physically and mentally. Kelsey and Ross are so upbeat, motivating and intentional with their programming and cues. I'm always excited for new programs and the variety of workouts keeps me engaged.
Joining the Sweat Den community has been one of the best things I’ve done for myself! Kelsey and Ross are so knowledgeable and have used their skills to curate a fun, results-driven platform that is truly unmatched. The programs target a variety of specific goals— I have even used them through pregnancy and postpartum.
I have never felt stronger, and it’s all thanks to their motivation and workouts that make me feel great physically AND mentally. They go above and beyond to support each member. They have built an incredible community that is all about helping each other strive to be the best version of themselves. Thank you Kelsey and Ross for providing this platform!
Kelsey and Ross put together high quality workouts with a focus on building muscle, being present, and striving to be your best self!
No membership out there is going to compare to Sweat Den! The community Kelsey and Ross have built is extremely uplifting and authentic. The workouts are challenging, time sensitive, and diverse, making it a worthwhile commitment that your body will thank you for! I LOVEEEE ME SOME SWEAT DEN <3
I joined Sweat Den in 2020 and have seen incredible changes in both my physical and mental strength over the past 3 years. The workouts are dynamic, high energy, results driven, and will leave you wanting more! Sweat Den takes a holistic approach to fitness and has helped me become the healthiest and strongest version of myself. It’s truly one of a kind!
My cousin, Brittany, got me into Sweat Den post having Lumbar Spinal Fusion Surgery. The workout is as intense as you want to make it with a main focus on form, stability, and confidence, which really helped me reach my fitness goals post surgery. Kelsey and Ross are so fun and energetic there is absolutely never a dull moment in these workouts. I honestly cannot recommend Sweat Den enough!
Ps. The merch slaps
Best of the best! I’ve been training with sweatden for over 3 years and it’s my holy grail!! Workouts are hard but they motivate and push you while putting tons of emphasis on form. It really feels like a personal training session every class. Cannot recommend enough!!
I’m a longtime-group fitness client and barre instructor, have tried tons of classes and online workouts, and hands down Sweat Den is the BEST training. Such enthusiastic, expert workouts that are thoughtfully programmed. And so many options!
I have been training via the Sweat Den Method for over 5 years now and I have yet to find any other approach/method as intentional, tailored, and results-driven as Sweat Den. I simply cannot recommend this studio enough!
I have tried numerous online forums; none even come close to Sweat Den. Ross and Kelsey are the only workout instructors that show modifications for beginners through advanced, meaning I could safely work out through pregnancy and postpartum. I look forward to new programs. My only compliant is that I would like them to release more clothing items,
Kelsey and Ross are inspiring and so positive! Be careful - you have to work hard at Sweat Den but the results are so worth it! Can’t wait for the new studio to open!
I started working out with Kelsey in 2018 when she was teaching pilates in Cherry Creek, and then I joined the virtual Sweat Den community during COVID (with my 70yo mother-in-law!). She and Ross are the absolute best. The workouts are hard but fun, and they do a great job of keeping you motivated. Would highly recommend them to anyone regardless of your fitness level or age.
Love the energy and balanced approach. The online library saves me, and the new programs always feel fresh and like a nice change of pace.
I have found my workout home! Kelsey, Ross and everyone that they have brought on are all SO motivating, SO knowledgeable, SO kind and effortlessly cool. You will understand once you see this chic space and hear the playlists. I have been working out for decades, and I think this is the first place that I look forward to going to class. It's hard, it's fun and it is filled with people who you want to be around. Thank you for creating this little workout heaven.
Loved this studio, the energy, the music, the workout! I was in town for work and decided to venture out from my normal hotel radius. Exploring platt park was great and the Sweat Den did not disappoint. The workout was hard, but could totally modify. The instructor was very helpful and motivating. She even gave me a shoutout for doing so well my first class :) I wish there was something like this with this vibe in St. Louis. There is a super cute coffee shop across the street too (it’s super craft coffee though so takes longer than your usual coffee stop). Take advantage of their 1st class free if it’s still available!!! 10/10 will be back next time I’m in town.
I wish I could give this place 10 stars. I've been taking fitness classes for 15+ years and this is the first studio I've found in Denver that infuses their classes with positive and inspirational energy each and every day. I took one class out of curiosity and have since returned every morning since, taking 5-6X per week. In the past 3 months since joining Sweat Den, I've felt a true shift in my body and mindset and honestly feel sad when I have to miss a class. The founders, Kelsey and Ross are both incredible motivators but so are the other teachers they hire! It's rare to find a studio where I'd be happy to take from any teacher on the schedule and I truly feel that way. Keep it up Sweat Den and thank you for bringing your passion and grit to the Denver community.
Love this great addition to the Platt Park neighborhood. Excellent workout, positive energy and fun! I hope to be back again really soon.
What a special place! The atmosphere and energy you get here is unlike any other. Coming to a workout when you’re 7 months pregnant is definitely intimidating to say the least, but not when you’re working out at SweatDen. Kelsey & Ross are so incredible and made me feel welcome every single time I walked onto my mat. They never failed to make sure that I was feeling good and were there to make sure I felt 100% with the modifications. What really stood out to me is Kelsey giving me a specific modification during class and she took the time to hang right next to me and do it with me. There’s not many coaches like this. You can just tell the amount of love that has been poured into this place. Sign up for a class, even if you’re in a place and feeling like “you don’t know where to start.” This is the place to start. You will not regret it.
Kelsey and Ross are simply the best. They have worked tirelessly to build a culture of health, support, motivation, and inspiration that truly holds water with Sweat Den. I am healthier and happier after having spent years training with them - both virtually and in-person. They actually live their mantra that “EACH DAY IS A BONUS” and they exude that feeling to all who are lucky enough to train with them. Simply awesome humans running Sweat Den!
The Sweat Den’s atmosphere is welcoming, non-judgmental, positive, encouraging and the workout is SO good! I love that each class offers different ways of training your muscles, hitting them at every angle in smart, proper movements. Every class is thought out to keep your mind and body on point and engaged. Classes are mindful, energetic, focused and challenging, I feel the burn 🔥 every time!!!
I cannot say it enough….but Sweat Den is IT! Kelsey and Ross have built not just an amazing work out platform but a community where you can leave it all on the mat. I am a breast cancer survivor, and after multiple surgeries and 12 rounds of chemo, I feel grateful to have a space where I can move my body and push myself to lift weights I never thought I would be able lift. I am 70 classes in and I feel stronger than I have ever felt. If you haven’t tried a SD class yet….sign up now!!
Sweat Den has created a space unlike any other that I have come across. They actually incorporate the key elements together that others just speak to… and they lead by example. Commmunity is real, workouts are challenging, yet my body feels the best it has ever felt. The Breathwork and mindfulness classes are the cherry on top to an already stand out place.

There are no words to explain the gratitude and love I feel for Sweat Den since I started as a client of Kelsey’s almost 10 years ago. It’s more than fitness. It’s a lifestyle of positivity and fitness for your mind body and spirit. Even after sadly moving across the country I can still feel their energy and I will hold their guidance and energy with me forever. I will to continue to plan my trips to Denver around the studios schedule!
I find the sweat classes to be a great complement to my other exercise and activities because it encompasses a range of movements that are different. Good vibe in the room - the music and the instructors make it fun!
Kels and Ross are absolute gems....they motivate you and support you all at the same time. You won't find a better group of people with more passion for helping others than you will find at Sweat Den.
I am so thankful I found SweatDen! It is hands down the best virtual platform I have ever used. Kelsey & Ross are intentional and thoughtful with their programming. I cannot recommend them enough!
Awesome program. Perfect amount of time and 4 days a week is great. Big fan of sweat den!
Denver resident since 2005, I have tried numerous locally owned gyms and classes. I am truly loving the simplicity, energy and effectiveness of SweatDen. Great space, team and clientele. Highly recommend!
I found Sweat Den during the uncertain times of COVID and it quickly became my go-to for daily workouts. Since then, I've never looked back. Each class is carefully planned, delivering a unique and effective workout every time I hit play. Kelsey and Ross infuse each class with their expertise, positivity and wit. What sets Sweat Den apart is their dedication to their community. While I love my virtual workouts, I can't wait to experience the energy of an in-person class. If you're considering joining Sweat Den, don't hesitate – you won't regret it.
I’ve been a Sweat Den member since the pandemic and started working out from home virtually! This was the best thing to happen to me during this time!! It changed me physically and mentally. Kelsey and Ross are two of the most motivating individuals I’ve met in the industry. They are both the best at what they do! I can’t say enough good things about them and what they have created. I’ve recommended to several friends who agree. Highly recommended. Thank you Sweat Den!
THE BEST WORKOUT in Denver. . . every single time! Great energy, knowledge and results!
I've been using Sweat Den's online platform for the past 2 years on and off, and the experience goes beyond logging in and participating on-demand workouts.
I wish I still lived in Denver so I could be a part of their in-person studio; they bring a contagious sort of magic into their workouts and programming that is hard to find anywhere else!
The Sweat Den team personally responds to questions via email about specific modifications (fertility, IVF, and pregnancy) and provides additional resources like nutrition recommendations and education on the "whys" of the training methodologies that they employ in their classes. I truly feel like they embody the "each day is a bonus" mantra that they often reference in their on-demand videos.
I've been an on-demand member since 2022. I've tried countless online classes and programs and none of them compared to Sweat Den! Ross and Kelsey push me to be the best version of myself and they’ve changed my life for the better! Sweat Den is so much for than just a killer workout, it’s a lifestyle, and the daily lessons it teaches me is immeasurable. Do yourself a favor and try Sweat Den, you won't be disappointed!
I joined Sweat Den this year after a fitness studio that I worked at had closed down. Fitness was my way to not only make me physically feel better but also mentally. I lost my way for a little bit until I stumbled into the Den. Not only did I love the workouts but Kelsey, Ross, and their team went out of their way to get to know me and my story and I immediately felt at home. Not only has my body composition completely changed from their programmed workouts but my mindset has completely shifted for the better (and I am in graduate school so sometimes it can be tough but I know at the end of the day, Sweat Den is exactly where I want to be after a rough day). All this to say I couldn't be more grateful I walked into the Den. Sweat Den made me fall in love with fitness and wellness all over again. Nothing beats the community of people I am surrounded by, the workouts, and the team. I highly recommend checking them out if you haven't yet! You won't regret it!!
Sweat Den is the best! I became a member a few months ago and have nothing but positive things to say. Exercise has always been important to me, but finding the time for effective and efficient workouts had become a challenge. Sweat Den is what I was missing! The instructors, workouts, and members simply rock! (Not to mention the on demand content is amazing, too!)
The energy, the people, the way I feel after leaving this place is all that needs to be said. Sweat den leaving us all in a better place because who wants to be average~
I started the Sweat Den program about a year after having my first baby. I had been going to pilates, but I wasn't consistent. I was looking for a program that aligned to my busy schedule while also helping me to achieve a stronger, toned body. Sweat Den was it for me. Kelsey and Ross know all about the body, they create programs that are motivating and entertaining! Thanks to them my body was in the best shape it's ever been in (even before having a baby!), I was consistent with my workouts and I was actually lifting weights, which I had never done before. I also love that they're local.
Sweat Den has my heart, and I’m a proud founding member as of December 2023. After ten years of bouncing around Denver's fitness scene, the trendy but repetitive workouts left me burnt out, especially as a mom navigating my postpartum body.
Sweat Den is different. Every detail, from the meticulously timed and stacked exercises to the mirror placement, is 100% intentional. It's a testament to the brilliant minds of Kelsey and Ross. Their program and class formats cycle through different phases, keeping workouts fresh and challenging. You can tell they've poured their hearts into this.
Every exercise has at least two modified versions, making Sweat Den accessible for every BODY and fitness level. The instructors genuinely care about each member, taking the time to learn your name and check in, and build you up throughout class. You'll also find yourself sweating alongside some truly amazing humans – from fellow parents to local business owners and other professionals. It's a humbling reminder that everyone is on their own fitness journey, and we're all in it together at Sweat Den.
TLDR: Sweat Den has transformed how I feel. I'm stronger, more capable, and truly feel like I belong to something bigger than myself. If you're looking for a workout that pushes you, supports you, and feels like more than just exercise, Sweat Den is it.
I have been training with Kelsey and Ross on their online platform for most of the last 4 years. After years of participating in competitive sports where we didn’t focus a ton on lifting (not great…), I was desperate for a training program that taught me proper form, ultimately protecting me from injury. As a result of joining Sweat Den, I’ve developed more strength in a safe and strategic way. I’m so grateful to Kelsie and Ross for their expertise and guidance. I think lots of people can benefit from their workouts and overall approach to tackling each day!
This is by far the best studio in Denver! Gorgeous studio with the best community of like minded individuals getting after shaping their mind, body and soul. Kelsey and Ross are the most welcoming owners who thoughtfully curate every single workout. Can not recommend this place enough 10/10
Where do I begin...
Hands down the best and kindest trainers I've ever had the pleasure of working out with. Their investment in everyone's fitness journey is obvious and genuine. The workouts are consistently challenging, and there is a format for everyone's preferences, though rotating through them all weekly keeps my interest, and I am able to balance all aspects of upper body, lower body and core. Sweat Den is a community that is encouraging and kind, not competitive and intimidating. But I think the thing I like most about what they have built - they focus on fitness, but also on health and wellness. They encourage you to take what you need to ensure you are your best self, including rest, breathwork, nutrition, mental health, appreciation for the body and how lucky we are to be able to move.
12/10 would recommend trying a class, or 5!
During the peak of the pandemic, my family and I embarked on a transformative journey with the Sweat Den. With the closure of schools and a rigorous work schedule that stretched from 7 am until 11 pm, our physical and psychological well-being was severely tested. Like countless families across the globe, we were faced with tremendous challenges that seemed insurmountable. However, amidst the chaos and uncertainty that engulfed us, Ross and Kelsey stood tall as beacons of hope and resilience.
Their unwavering commitment to promoting physical wellness and psychological first aid was nothing short of revolutionary. They offered complimentary online classes that not only helped me minimize trauma but also provided an avenue of creative expression for my kids. Their online community and platform became a sanctuary where we could play and move to the music, fostering a sense of connectedness that we desperately needed.
Through their selfless efforts, Ross and Kelsey made an indelible impact on the global community at a time when the world shut down, and people needed it most. Over the years, Sweat Den has grown alongside our family, providing us with constant support and nourishment. As we continue on our journey of recovery and healing from the stresses of everyday life as professionals and parents, Sweat Den remains a steadfast source of inspiration.
We believe in the power of Kelsey and Ross's hearts, which long to serve and grow in the community through wellness. Their compassionate leadership and unwavering dedication to promoting physical and psychological well-being have transformed our lives in ways that are impossible to quantify. For that, we are eternally grateful.
I joined Sweat Den in October 2023 when their new location opened & have been completely blown away by their studio. The instructors, programming, community - 10/10.
I honestly don’t feel like I have adequate words to describe how impactful this place has been for me. Since its flagship studio opening in October, I have seen the most positive changes to my body, mental health, and overall resiliency both physically and emotionally. I have never seen my body respond so quickly and drastically to programming before. And while I will always keep coming back for the workout, it’s community of instructors and members that have made the difference in my experience. This is one of the few spaces I feel like I can show up exactly as I am and walk out feeling stronger, empowered, and supported. Like I told one of the founders recently, I don’t want to live in a city where Sweat Den doesn’t exist. This place is life changing. Dramatic? Maybe. Accurate? 100%.
Truly the best founders, instructors, programming, values, energy, members, and space.
By far the best workouts I have ever done. So thoughtfully constructed and taught. Kelsey and Ross have built such an amazing, inclusive community. They are incredibly supportive and motivating and lead by example. All of the instructors are the best at what they do. I feel stronger and more focused after every class. I am so grateful to be part of the Sweat Den community!
SweatDEN is an awesome fitness community! Everyone on their team makes you feel welcome and inspired and the workouts are fire!
there’s a reason sweat den has the reputation it does! the community is great, workouts are perfectly programmed, and you leave with a sense of gratitude to start the day. Getting to focus on yourself in the space Kelsey and Ross and the team have created is incredible.
Sweat Den has become such an important staple in my life. Not only do they offer well rounded classes that challenge you but are also fun, but the community that they have created is amazing! I have made many friends in my different classes and love to cheer each other on as we hit each milestone. No other group fitness offers the programming they do and it can't be beat. Forever grateful they opened when they did!
I have belonged to boutique fitness studios for over ten years but nothing compares to Sweat Den. The workout, the community, the joy, the push, everything about it makes you want to show up every week. It pushes you but you want to be pushed. I had two spinal surgeries and couldn't lift 3 lbs in October. I'm now lifting 25 lbs and have zero back pain for the first time in 4 years. That speaks for itself. Come try it - you won't regret it!!
Seriously just go and join! I love that SD is a real community, the classes are so hard but a freaking blast, the music is always on point and the vibes are high. I had a hard time finding a gym where I would not only like the workout, but actually want to go regularly. The different formats keep the workouts fresh and the instructors are very attentive to form and ensuring people don’t injure themselves. Love this gym and the way they bring people together!
Absolutely LOVED this workout. So challenging but fun. Wendy is the best and kicks your booty in the best way possible!
Even from afar every workout has been simply amazing. Every time I turned on the workout I felt like I was right there or they were talking directly to me when I wanted to give up or give in. Ross and Kelsey do an amazing job at building and creating this community to empower and push further than most would at home!
Every moment with Kelsey and Ross and the entire Sweat Den crew is a challenge and a blessing. The variety of workouts challenge you in the most amazing ways and they always have so many modifications for all levels and abilities. Kelsey and Ross are the real deal with so much knowledge and experience while still being completely down to earth and genuinely caring about their members and community. Whether you are in the Den or joining virtually, you will not regret the time you spend with them…and your body will thank you for it!


I have known and been working out with Kelsey and Ross for just shy of a decade. They are MY FAVORITE! Positive encouragement through challenging workouts. Love these two.
The best of the best. Their knowledge of and passion for fitness, health, nutrition, and optimizing your days is contagious and infectious. Their programs are challenging, efficient, and fun. No matter where you are or how much time you have, there's a Sweat Den workout for you. Masters of their craft!
5 stars is truly not enough!!! I've tried multiple workout platforms over the years and nothing really stuck long-term. After doing some of Kelsey's iFit running series, I came across the Sweat Den on-demand and was absolutely hooked from day 1. Working out used to feel like a chore and I did it just to check it off the list; now, I honestly can't wait to work out and look forward to it every day!! The series are so well structured and I've noticed such a huge difference in my physical and mental well being. Kelsey and Ross are so encouraging and fun - it feels like I'm working out with friends :) Cannot say enough good things about it!!!
5 stars isn’t enough to describe how amazing Sweat Den is for the body, mind and soul. Kelsey and Ross create such a unique environment and community that can’t be found anywhere else! They inspire strength, mobility and above the mindset that anything can be achieved. My life wouldn’t be the same without the Den.
I swam competitively in college and missed having a consistent challenging program. I appreciate the variety and thoughtfulness behind the workouts. There are a lot of programs out there, but you really get quality with Sweat Den. Post two babies now it has given me the confidence and strength to get back into triathlons.
I have been training online with Sweat Den since 2021, after working out with Kelsey’s running and strength programs on iFit . It truly is the best online community and platform I have known. Kelsey and Ross are engaging, fully knowledgeable and know just how to motivate you to become the best you can be physically and spiritually. The thoughtfully tailored strength programs, live classes and immense video library (strength, tempo, sweat, sculpt, mobility, and much more) make it so easy to get my workout done at any time I need, in the comfort of my home. Kelsey and Ross encourage their community to interact amongst ourselves, making friends, encouraging and helping one another to strive for our best. Thanks Sweat Den!
Sweat Den is the absolute best! The workouts are incredible, Ross and Kelsey are so inspiring and their workouts have helped me to be the strongest version of myself! 10/10 recommend!!
I can’t say enough about Sweat Den! This community is built on so much then just a workout. Kels and Ross think about you as a whole!! They think about your mind, body and soul! I am a Sweat Den member for life!
I feel fortunate to have experienced Sweat Den in both an in-person training environment and virtual environment. The energy, vibe, workout and coaching are exceptional to say the least. I strongly recommend this business to anyone and everyone for more reasons than I have time to list!
Such a great gym and the best trainers / staff! 10/10 recommend checking this place out 🤗
I’ve been training with Kelsey and Ross nearly since the start of Sweat Den, both in person and the online platform, and I can say there’s no better workout or community. The energy that Kelsey and Ross bring to every workout is so positive, motivating, and leaves me feeling so encouraged. They do a great job at pairing challenging workouts with mindfulness, allowing both body and mind to become stronger and more present.
I started with Sweat Den early on during the pandemic. I had just had a baby and not only did SweatDen get me moving again, but Kelsey and Ross made me smile and laugh while working out. The best part was how much I built strength not just physically but emotionally and mentally! The community is a special, unique one and I am honored to be a part of it.
Ross and Kelsey rock! I am so happy I found them almost a year ago now! They know their stuff! They are fun! They are inspirational! They are motivating! And, above all, their positivity wraps it all up like a pretty little bow! Do yourself a favor and sign up now!!
I've never liked instructors or classes before I found Sweat Den. Kelsey and Ross create a down-to-earth, no pressure atmosphere yet you always feel so encouraged and energized by them. The workouts are addicting and the results are real.
I started Sweat Den this year to focus on building muscles after having two babies in 18 months. I love the online platform and the ability to follow a thoughtfully designed strength training program that lets you progress week to week. Kelsey and Ross are so motivating in their videos, it actually makes me want to stick with the routine. I just wish I lived in Denver so I could join their soon to be brick and mortar gym!
I started doing Sweat Den in 2020 and have been hooked ever since - Kelsey and Ross are the perfect duo to encourage you, push you and keep you accountable. The programs and different workout formats have helped me achieve so many fitness goals and I feel stronger than ever (I keep having to buy new weights!). So thankful I found this community, it’s truly become a staple in my routine and a key to overall well-being.
I've been training with Sweat Den roughly 5 years now. Both in the Den and online through their virtual platform. There is nothing like the energy that Kelsey and Ross bring to the table. Every time i would leave training sessions I couldn't believe how far I was able to push my body and how great I felt mentally. I relocated to Georgia, but continue to train with them virtually. Their programs have been a staple getting me wedding ready, through pregnancy, and now post-partum. No matter the phase of life you are in Sweat Den is it. LOVE LOVE LOVE!!!
Wish I could give more than 5 stars. Sweat Den is the best - it has gotten me into the best shape I've ever been. But more than that, it has made me love to work out - I look forward to my workout each day. Kelsey and Ross are so positive, they keep me motivated in the gym but also inspired outside of the gym to be my best self. I am so thankful for Sweat Den!
I have been training at Sweat Den for 3.5 years and it has absolutely transformed my physical and mental health. Kelsey and Ross are incredibly knowledgeable fitness professionals who truly pour so much time and energy into their platform and community. They offer a huge variety of class formats with modifications and variations in every exercise to suit each individual's fitness level - over my years of training with them I used their programs through my entire pregnancy as well as postpartum and onwards. I cannot recommend their studio enough!
I've been training with Kelsey and Ross since 2017 and haven't looked back! Both in studio and at home, they bring knowledge and energy that is unmatched. They offer a variety of thoughtfully programmed workouts- all just as challenging as the next. Don't sleep on Sweat Den! They are the best of the best!
Kelsey and Ross are amazing! I had struggled for years to get back in shape and the Sweat Den programs are what finally got me there. They are fun, engaging and as challenging as you want to make them.
I was first exposed to Kelsey from one of her iFIT running programs where she enthusiastically coached me back into running. However, what really made the difference was adding the Sweat Den programs to the cardio. Not only did I lose pounds but I lost inches and am in the best overall conditioning of my life!
Everyone needs to know about Sweat Den. I joined in 2020 when I was pregnant for the first time, and was able to do every workout during my pregnancy. Kelsey and Ross provide modifications to meet you wherever you are in your fitness journey, making the workouts accessible for everybody. I am now on my third pregnancy, and can say that Sweat Den is the gold standard of workout platforms.
When I was cleared to workout postpartum, I didn't feel like I was starting over. I had gotten stronger by following the Sweat Den programs and, with a lot of modifications, was able to jump back into my routine.
The virtual/on demand workouts have been a lifesaver during this phase of life. As a busy mom of young kids, my schedule is unpredictable. Being able to squeeze in a 30 minute workout at home is an invaluable piece of maintaining my sanity.
Finally, the workouts pack a serious punch. 30 minutes or "low impact" does not mean easy. They are HARD. It is truly like having a personal trainer in your home. Kelsey and Ross are extremely knowledgable in anatomy and the process of building and maintaining lean muscle. So not only are the workouts safe, but they are designed to push you to get stronger. I have learned so much about building muscle just from listening to them during the workouts. They always say that "we are the lucky ones", so if you're able to workout, you should take advantage of a Sweat Den class ASAP!
Sweat Den is a game changer for sure! If you’re looking for challenging workouts of all varieties, trying to get back into a fitness routine, or brand new and looking for guidance…
Kelsey and Ross know how to bring it and have built an amazing community. Give it a month and tell me you’re not hooked- I dare you!
Sweat Den is the best! The workouts are for all levels and the energy and banter Kelsey and Ross give off is infectious. And when you’re convinced you can’t go anymore, you hear the best words “last set, best set” and you have to power through because, why not?! The work outs range from 20 minutes to 45 minutes, so you can make it fit into your day. And with Swear Den, it isn’t about the quantity of time, just the quality of the workout. Kelsey and Ross are not only amazing and inspiring, but they are so down to earth and understand real life. Not only are they the best, but the entire Sweat Den community is absolutely amazing!
Sweat Den has been a complete game-changer for my workout routine — I feel stronger than I ever have, both physically and mentally. Kelsey and Ross are so upbeat, motivating and intentional with their programming and cues. I'm always excited for new programs and the variety of workouts keeps me engaged.
Joining the Sweat Den community has been one of the best things I’ve done for myself! Kelsey and Ross are so knowledgeable and have used their skills to curate a fun, results-driven platform that is truly unmatched. The programs target a variety of specific goals— I have even used them through pregnancy and postpartum.
I have never felt stronger, and it’s all thanks to their motivation and workouts that make me feel great physically AND mentally. They go above and beyond to support each member. They have built an incredible community that is all about helping each other strive to be the best version of themselves. Thank you Kelsey and Ross for providing this platform!
Kelsey and Ross put together high quality workouts with a focus on building muscle, being present, and striving to be your best self!
No membership out there is going to compare to Sweat Den! The community Kelsey and Ross have built is extremely uplifting and authentic. The workouts are challenging, time sensitive, and diverse, making it a worthwhile commitment that your body will thank you for! I LOVEEEE ME SOME SWEAT DEN <3
I joined Sweat Den in 2020 and have seen incredible changes in both my physical and mental strength over the past 3 years. The workouts are dynamic, high energy, results driven, and will leave you wanting more! Sweat Den takes a holistic approach to fitness and has helped me become the healthiest and strongest version of myself. It’s truly one of a kind!
My cousin, Brittany, got me into Sweat Den post having Lumbar Spinal Fusion Surgery. The workout is as intense as you want to make it with a main focus on form, stability, and confidence, which really helped me reach my fitness goals post surgery. Kelsey and Ross are so fun and energetic there is absolutely never a dull moment in these workouts. I honestly cannot recommend Sweat Den enough!
Ps. The merch slaps
Best of the best! I’ve been training with sweatden for over 3 years and it’s my holy grail!! Workouts are hard but they motivate and push you while putting tons of emphasis on form. It really feels like a personal training session every class. Cannot recommend enough!!
I’m a longtime-group fitness client and barre instructor, have tried tons of classes and online workouts, and hands down Sweat Den is the BEST training. Such enthusiastic, expert workouts that are thoughtfully programmed. And so many options!
I have been training via the Sweat Den Method for over 5 years now and I have yet to find any other approach/method as intentional, tailored, and results-driven as Sweat Den. I simply cannot recommend this studio enough!
I have tried numerous online forums; none even come close to Sweat Den. Ross and Kelsey are the only workout instructors that show modifications for beginners through advanced, meaning I could safely work out through pregnancy and postpartum. I look forward to new programs. My only compliant is that I would like them to release more clothing items,
Kelsey and Ross are inspiring and so positive! Be careful - you have to work hard at Sweat Den but the results are so worth it! Can’t wait for the new studio to open!
I started working out with Kelsey in 2018 when she was teaching pilates in Cherry Creek, and then I joined the virtual Sweat Den community during COVID (with my 70yo mother-in-law!). She and Ross are the absolute best. The workouts are hard but fun, and they do a great job of keeping you motivated. Would highly recommend them to anyone regardless of your fitness level or age.
Love the energy and balanced approach. The online library saves me, and the new programs always feel fresh and like a nice change of pace.
I have found my workout home! Kelsey, Ross and everyone that they have brought on are all SO motivating, SO knowledgeable, SO kind and effortlessly cool. You will understand once you see this chic space and hear the playlists. I have been working out for decades, and I think this is the first place that I look forward to going to class. It's hard, it's fun and it is filled with people who you want to be around. Thank you for creating this little workout heaven.
Loved this studio, the energy, the music, the workout! I was in town for work and decided to venture out from my normal hotel radius. Exploring platt park was great and the Sweat Den did not disappoint. The workout was hard, but could totally modify. The instructor was very helpful and motivating. She even gave me a shoutout for doing so well my first class :) I wish there was something like this with this vibe in St. Louis. There is a super cute coffee shop across the street too (it’s super craft coffee though so takes longer than your usual coffee stop). Take advantage of their 1st class free if it’s still available!!! 10/10 will be back next time I’m in town.
I wish I could give this place 10 stars. I've been taking fitness classes for 15+ years and this is the first studio I've found in Denver that infuses their classes with positive and inspirational energy each and every day. I took one class out of curiosity and have since returned every morning since, taking 5-6X per week. In the past 3 months since joining Sweat Den, I've felt a true shift in my body and mindset and honestly feel sad when I have to miss a class. The founders, Kelsey and Ross are both incredible motivators but so are the other teachers they hire! It's rare to find a studio where I'd be happy to take from any teacher on the schedule and I truly feel that way. Keep it up Sweat Den and thank you for bringing your passion and grit to the Denver community.
Love this great addition to the Platt Park neighborhood. Excellent workout, positive energy and fun! I hope to be back again really soon.
What a special place! The atmosphere and energy you get here is unlike any other. Coming to a workout when you’re 7 months pregnant is definitely intimidating to say the least, but not when you’re working out at SweatDen. Kelsey & Ross are so incredible and made me feel welcome every single time I walked onto my mat. They never failed to make sure that I was feeling good and were there to make sure I felt 100% with the modifications. What really stood out to me is Kelsey giving me a specific modification during class and she took the time to hang right next to me and do it with me. There’s not many coaches like this. You can just tell the amount of love that has been poured into this place. Sign up for a class, even if you’re in a place and feeling like “you don’t know where to start.” This is the place to start. You will not regret it.
Kelsey and Ross are simply the best. They have worked tirelessly to build a culture of health, support, motivation, and inspiration that truly holds water with Sweat Den. I am healthier and happier after having spent years training with them - both virtually and in-person. They actually live their mantra that “EACH DAY IS A BONUS” and they exude that feeling to all who are lucky enough to train with them. Simply awesome humans running Sweat Den!
The Sweat Den’s atmosphere is welcoming, non-judgmental, positive, encouraging and the workout is SO good! I love that each class offers different ways of training your muscles, hitting them at every angle in smart, proper movements. Every class is thought out to keep your mind and body on point and engaged. Classes are mindful, energetic, focused and challenging, I feel the burn 🔥 every time!!!
I cannot say it enough….but Sweat Den is IT! Kelsey and Ross have built not just an amazing work out platform but a community where you can leave it all on the mat. I am a breast cancer survivor, and after multiple surgeries and 12 rounds of chemo, I feel grateful to have a space where I can move my body and push myself to lift weights I never thought I would be able lift. I am 70 classes in and I feel stronger than I have ever felt. If you haven’t tried a SD class yet….sign up now!!
Sweat Den has created a space unlike any other that I have come across. They actually incorporate the key elements together that others just speak to… and they lead by example. Commmunity is real, workouts are challenging, yet my body feels the best it has ever felt. The Breathwork and mindfulness classes are the cherry on top to an already stand out place.

There are no words to explain the gratitude and love I feel for Sweat Den since I started as a client of Kelsey’s almost 10 years ago. It’s more than fitness. It’s a lifestyle of positivity and fitness for your mind body and spirit. Even after sadly moving across the country I can still feel their energy and I will hold their guidance and energy with me forever. I will to continue to plan my trips to Denver around the studios schedule!
I find the sweat classes to be a great complement to my other exercise and activities because it encompasses a range of movements that are different. Good vibe in the room - the music and the instructors make it fun!
Kels and Ross are absolute gems....they motivate you and support you all at the same time. You won't find a better group of people with more passion for helping others than you will find at Sweat Den.
I am so thankful I found SweatDen! It is hands down the best virtual platform I have ever used. Kelsey & Ross are intentional and thoughtful with their programming. I cannot recommend them enough!
Awesome program. Perfect amount of time and 4 days a week is great. Big fan of sweat den!
