So what is btone FITNESS?

No matter your current fitness level, age, size, or mood, btone is customizable, lighting fast, and wildly effective.

btone doesn't fit into any singular group-x description, it is truly a new category of exercise: and one that was formed out of an urgent need for an intelligent and sustainable approach to fitness that wouldn’t eat up 2 hours of your day, and that delivers real results, without destroying your cartilage.

Built around state-of-the-art equipment, our custom-engineered btone FITNESS arkeTONE, which we call TONEy for short, delivers an efficient, modifiable, comfortable, and challenging experience that you'll feel for days after your workout.

It's basically the very best of Personal Training + Yoga + TRX + Pilates.
All in one, 45min package.

btone Fitness is a great studio with fantastic instructors that provide very challenging workouts!

And I love it! I have only been taking classes for a little over 5 weeks (2-3/week) and can already note a huge improvement in my overall strength (upper and lower body and core). I have definitely improved my fitness, trimmed up, and don’t feel pain in my knee any longer.

A big thanks to the great staff and instructors for being so motivating even when I don’t think I can do even one more rep!

btone's Signature TONE Class

Through a unique series of zero-impact, joint loving exercises, this 45-minute class hits every muscle in your body.

Each class leverages our custom-crafted state of the art ArkeTONE Machine, a comfortable platform with 7 sets of springs. You'll experience a smooth, gliding resistance that is 100% customizable leaving you just-the-right-amount of sore. No two classes are ever the same, and all of our expert instructors are ready to give you modifications so your TONE fits you to a T.

You'll build long, lean muscle, that tones and balances your whole body. While the movements are slow, they are challenging and create the perfect atmosphere for heart-rate driving cardio through precision low-impact, high-intensity movements. TONE is a joint-loving, muscle-shaking, surprisingly entertaining experience.

Perfect for all levels, all ages, every body, every day (ok, maybe not EVERY day - 2-3 times/week is more than enough).
