Combines Pilates-inspired movements with classic abdominal toning. You'll increase the strength and flexibility of your “core” muscles, the muscles that support and stabilize your entire body. Karen's unique complementary design optimizes safety and effectiveness. For example, a contracting movement is followed by a lengthening motion. Or a back-muscle move is followed by an ab routine (usually integrating the legs and arms to vary the intensity). Lots of modifications, exquisite cuing and quiet instrumental music. ©2000.
