Tone House 

Where: New York

Often called “The Hardest Workout in New York”, Tone House was founded by a former professional athlete and uses the principles of sports conditioning to work your body in all directions. Each workout begins and ends with a group chant to create that team atmosphere that keeps you pushing through the explosive intervals, complete with active recovery periods, velocity training and resistance training.  While each class is different, you can expect to try out plenty of “fitness toys” like TRX, plyo boxes and training ropes.
