About us

what is duality?

We strive to be a house of personal development — a space where being deliberately uncomfortable drives us to seek more. Our studio is a home for safe struggle, welcoming all perspectives on strength and weakness. Each day, we dedicate one hour to releasing intentions and rediscovering them through sweat. We work to remove the idea of limits, fostering freedom and expression over achievement. Our practice serves as a mirror, reflecting mindfulness and insight. Here, we own our challenges, embrace reality, and adapt to constant change by finding balance in our day-to-day.

the steam that moves the engine

At Duality, we're passionate about building a community where you can push limits, feel supported, and enjoy every step of your fitness journey - both in and out of the studio.

Testimonials

the word on duality

"So hot & hard! Music was 🔥. I just moved here and have been exploring lots of studios. Arkady is definitely one of the better/harder instructors I've experienced in Denver so far!"

Anonymous Student Review

"Best Gym I've ever been to. The trainers are super helpful and push you beyond your mental and physical threshold. I love the mix of high-intensity training combined with the stillness and focus of yoga. Extremely clean studio with a fun community. Highly recommend!"

Anonymous Member Review

"Been a member for 2.5 years and it's awesome. One of the best HIIT studios you will find not only in Denver, but anywhere. I've never done the same workout twice -- which I love. The variety, friendliness of the coaches along with their stellar music selection and awesome workout tips make this the place to be. 5/5 stars!"

"Duality is my absolute FAVORITE workout studio in Denver. I’ve been a member for over 2 years and can easily say I’ve found more than just a good workout here. I keep coming back not only for the killer workouts, but for the community and for the amazing people I’ve met."

"I can not recommend Duality enough! I love all of the formats that are offered and all of the coaches truly push you in the best way possible. Taking classes at a gym can be intimidating, but I’ve found Duality to be a super welcoming community that provides its students with well-rounded, challenging workouts :) Very very grateful to have found this amazing gym!!"
