BOSU® stands for “Both Sides Up.” The semi-spherical BOSU trainer is an inflated bubble on one side and a hard, plastic surface on the other and is used in this class on both sides. Through dynamic, choreographed exercises and drills using the BOSU half ball platform, you’ll develop functional core strength, flexibility and balance, cardio endurance, and agility.

A Typical Class

Class begins with warm-up exercises. The BOSU workout follows, using the BOSU balance trainer for an intense core workout consisting of sit-ups, crunches, back extensions, standing and balancing. Class ends with cool down exercises and stretching.
