Formula is my favorite class at Physique57. It just seems like a perfect combination of legs, arms and abs -- or is it a perfect formula? :) I highly recommend this class to anyone who tried Physique and got discouraged or frustrated by not being able to keep up with all water ski and other unbearable exercises that involve thigh pulsing. formula concentrates on different muscle groups and still works the hell out of your seat and legs.
Chanelle is a great instructor and did I mention that she is the one who designed Formula57? You are up for a treat! Book in advance, her classes get sold out fast!
