TONE classes are a Pilates-based workout infused with cardio and strength training for absolute body transformation! It is the most aggressive and innovative approach to optimal body sculpting. Strengthen, tone and lengthen the entire body in just 45-minutes! It will leave you feeling challenged, shaky and in no time, TONEd.

Indo Row®

Also known as "the PERFECT calorie burn." Working in teams, partners and as one crew, Indo-Row® gives you a transformative total-body workout that challenges the body and focuses the mind. The Indo-Row® on-water team dynamic builds an electric energy in you that is as positive mentally as it is physically exhilarating.

Barre Blast

Your heart beats faster. Legs begin to tremble. Arms turn to jelly. Breath gets heavy. You’re hot, sweaty… Been a while? Time to spice up your workout routine. Ditch the boring treadmill and wasted time at the gym, and redefine the way you sweat. Blast takes your heart on a roller coaster ride with the ultimate barre workout. No tutu required.

Tone N Torch

Think Megaformer meets bootcamp and there you have the TONE N TORCH format. 45 minutes of high intensity training with bursts of intervals on and off the Megaformer. This full body, calorie scorching, muscle quivering class is just what you need to kick it up a notch and see even more results at btone!


These sessions are held two times a week for 30 minutes of high intensity cardio and strength exercises. These classes are not done on our equipment and require a separate sign up. Join our mailing list or email the studio for details on how to join the next session!
