About Duality

Duality offers a unique fitness experience that combines high-intensity workouts with mindful yoga classes, promoting constant growth and development. This studio believes in balancing the mind and body, providing services that benefit both. With a variety of classes, including HIIT and yoga, members can experience it all under one roof. The trainers are fun, encouraging, and ensure safe lifting practices, while the facility is well-managed, clean, and inviting. Duality's programming is carefully created to keep workouts engaging and different, with classes like Circuit and ResCon. Members appreciate the welcoming atmosphere, where coaches make an effort to get to know them. The studio's convenient location, adjacent to a coffee shop and cocktail bar, adds to its appeal. Customers praise the exceptional hot yoga classes led by instructor Tim, who creates a motivating environment and encourages students to listen to their bodies. The community at Duality is described as supportive and inclusive, with a "feel-good" vibe that keeps members coming back. The addition of the nearby Side Pony Coffee provides the perfect post-class spot to unwind and socialize with fellow yogis.

I’ve been going to Duality for a minute now and this is long overdue. This is my favorite studio in Denver, hands down. There are so many options to choose from and no matter what I walk away feeling energized. Every single class is a stellar workout and every coach I have worked out with has been fantastic.

Jen N., Jen S., and Keira… y’all have helped me so much in finding my form and staying motivated. The mindfulness you all bring to class has made me a stronger athlete and I feel like I leave working out muscles I didn’t even know I had.

TLDR: Can’t recommend Duality enough!

Duality keeps me going! I had never joined a gym before, but I loved the variety of the classes. Even if it’s the same time every day, it’s different, and that’s what I need to stay engaged. The best part is that they make me feel welcome even though I’m probably oldest one in there by at least 2 decades! Thanks Duality!

Just took my first mat Pilates class here with Anna… immediately signed up for her next class. I loved the cues she was giving & reinforcing importance on the breath. You can tell she comes from a yoga background, which I really appreciated as a yogi myself! Can’t wait for my next class here 🌟
