I went to the "core strength and flexibility" class which replaces the body balance, and it wasn't bad. The girl; taking it, and the one who will be certifing in body balance next month was a different girl! she was good, not as experienced, but i think she will do! The class didn't have quite the same flow as body balance, but there were several yoga position and pilates moves that were in it that i knew. The class also had a lot of work on abs, and i feel it today!
