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.

Great workouts

Btone is a great workout. I have been attending classes for over 6 months now and I love it!

Lindsey, December 4, 2019

BTone was an amazing workout! It challenges your balance throughout, and while not feeling impossible at the time, every single muscle was sore (in a good way) the next day. Loved it!

Sarah, December 1, 2019

different way of working out than I’ve ever experience! Fun, upbeat pace, and easy enough to catch on during your first class

Michaela, November 22, 2019

Friendly and knowledgeable staff

good workout

Zakia, October 9, 2019

Very nice studio and great staff. Love the workout, the “slow” movements that isolate your muscles really work! Recommended

Great workout and instructor

Morissa, August 29, 2019

A great workout that’s easy on the joints but sure does make you break a sweat. Love the upbeat music, the instructors and the alternative moves offered for beginners.

BTone is great! So fun! I had a great time taking classes there and would definitely do it again.

Sylvia, July 29, 2019

Great class! Interesting and fun to try something new!

Kiley, July 28, 2019

Modern and clean studio. Very friendly and encouraging environment! Great workout!

Jenny, July 13, 2019

I had a great workout! I was dripping sweat. The whole day I felt great and now the next day I'm waking up a tad sore, I'm sure tomorrow I'll be feeling it even more. The machine was easy to get used to and the instructor was helpful and kind. I had to buy some grippy socks for safety, that have a lot to choose from. The reason why I don't recommend is because of cost. I love having the opportunity to take some free classes, but $30/class or even $25 as a bundle is a bit much for me.

Great workout

I enjoyed the social environment of the class.

Duojin, June 9, 2019

Amazing class! Will definitely be back!

Kate, May 20, 2019

The btone Waltham studio is terrific. It's a beautiful, clean studio. The 45-minute workout went by fast but you worked every muscle group. I would go back again.

Erin, May 19, 2019

Good work out. Be ready!

Deborah, May 9, 2019

I really enjoyed Btone - enough that I plan to make it a regular part of my week! It’s a totally different kind of workout, all about toning, using slow deliberate movements on reformers similar to the ones used in Pilates. You can feel it working!
