btone doesn't fit neatly into any category. It is not Pilates, or barre or yoga or TRX...btone is its own wild genus of exercise: and one that was formed out of a deep, universal need for an intelligent, sustainable approach to fitness that delivers real results, in THIS lifetime. Whether you're 19 or 91, the need for a workout that spares the joints, and transforms the body is the holy grail. btone is built around state-of-the-art equipment. Our custom-engineered btone FITNESS arkeTONE, which we call TONEy for short, delivers a challenging, completely adjustable, and endlessly engaging experience that you'll feel for days after the workout... And that's the point, and the Method. The science behind the post-class shakes Cultivating micro-tears in the deepest layer of muscles helps you grow non-bulky lean muscle mass, and a longer, leaner form — all while sparing your joints and your sanity. That shake-tremble, subtle-soreness you'll feel after class is proof that you're getting stronger, more resilient, and fitter — faster.

Beautiful facility. The instructor was great. I was a total rookie and she was able to manage my awkwardness without slowing down the others in the class. I definitely got a great workout!

It took one class to really get comfortable using the megaformer machine, but after that I got a great, challenging workout from my btone classes.

BTone is awesome! it's low-impact but intense! the instructors are all really patient and helpful and the moves are easy to follow, but work so many muscles.

Instructor was very friendly, helpful and attentive. Place was clean and modern looking.

CINDY, November 10, 2017

The classes were challenging, but several modifications were offered for various movements. All three classes incorporated different exercises, so it keeps you on your feet!

Haven't gone yet, but it's exactly what I was looking for! Thanks!

Bianca, June 13, 2017

so far i have gotten three nift coupons for three different place around Boston that i typically wouldn't try. One was to the blackmor which i loved and now live near. Another a liquor store which i mean how could you go wrong with that! The last btone i have been wanting to try but didn't want to spend the money seeing as i already belong to the equinox and its two hefty expenses.
