This is one of the best studios I have been to in Denver! It is one of few that has both strength/cardio classes as well as hot yoga. It is usually hard to find that combination. I did the circuit class and it was very challenging. The instructors are also very motivating and helpful. Highly recommend!

The Duality coaches are all amazing! I've never taken a class there that I didn't absolutely LOVE. From ResCon to Circuit to Flow, this gym truly has everything you need to feel energized, balanced, and strong! In a difficult time when all of had to adjust to the new normal, the Duality Team found ways to keep the community together (like offering socially distant and free Sloan's Lake HIIT classes) and partnering with Strength in the City to become more involved and present in the Denver fitness community. The owners care deeply about their students, each other, and the greater community and continuously offer up their own time and resources to give back to others. I could not recommend Duality highly enough for those who want a place that truly makes you feel seen and respected and where you can become your best physical and mental self. All the love Duality!

I LOVE DUALITY! It's the best workout ever! I tell everyone about Duality and encourage all to try out a class at every opportunity I get! I joined during the pandemic in spring of 2020 and absolutely loved how they kept fitness and their community alive doing live Instagram workouts and recorded sessions that I could turn to whenever I wanted. The instructors and fellow members create a positive, uplifting atmosphere for all of us to challenge ourselves and reach new heights - both in the studio and outside in the world.I am incredibly grateful for Duality as they helped keep me happy, healthy, and centered during some of the most tumultuous times over the past year and a half. Thank you thank you thank you!!!

This is my fave studio I've ever been to and is actually the only studio I've ever purchased an unlimited membership from, I love it that much. The workouts are amazing - challenging and unique but you can move at your own pace and do what's right for your body. The studio is relaxed and the instructors are cool but also super motivating and helpful (especially when you need to modify because of a recent surgery). You can really tell how passionate the instructors are, which makes all the difference. The rescon class if my fave class I've eve taken - heated, on your mat, some cardio but mostly strengthening, just so fun! And the circuit classes are amazing too, I switch back and forth. Vinyasa is amazing too, I just don't get around to those as much because I'm so addicted to how I feel after rescon and circuit, but flow is great for me on a 'rest' day.I've been a little hesitant to write this review because I don't want to lose my spots, but I know this studio will expand in the near future or get another location because it's just that good.First class is free - you have nothing to lose!

I live in Los Angeles and it goes without saying that my options for health and fitness classes are pretty much unlimited; I have access to some of the best fitness instructors in the world. Recently, I've found myself spending a lot of time in Denver and needed a place to work out. My only complaint about Duality is that I can't take this place back to LA with me; Duality blows every fitness studio I've ever been to out of the water. The classes are thoughtfully curated to be physically and mentally challenging. Jen and her instructors have a knack for pushing you to your absolute peak performance. That last rep that you think you can't possibly push yourself to do? Jen knows exactly what to say to pull two more out of you. I didn't know what my body was capable of until Duality. (Please open a studio in LA, my abs are depending on you)

I’ve experienced a number of gyms and yoga studios in Denver, and Duality ranks at the top. The coaching/teaching team holds itself to a high standard and that’s reflected in a great experience every time. If you have yet to check this place out, quit putting off a great time.

Duality saved my mental health. All of their instructors are amazing in fostering a welcoming environment for everyone on their fitness journey. You will feel supported while being pushed to your limit in the most amazing way. Duality has become an ingrained part of my routine that gives physical and mental strength and I will be a member for life.

I LOVE Duality!! Top quality workouts, equipment, space, and very friendly/welcoming staff and owners. I love that I can go there for intense workouts, and also lower intensity flow classes. If you haven't tried a class here do it NOW

Really knowledgeable instructors, great class formats, and an awesome studio (music, layout, equipment mix, etc.). They accept ClassPass, so I definitely plan on making this part of my regular routine!
