You’ll use a stability ball to enhance the effectiveness of a total body workout. The ball will boost resistance, increase range of motion, enhance core muscles, strengthens the back and improve balance. The first segment is ball aerobics (e.g. torso twists, side steps, knee lifts and kicks). The second segment is toning and floor work (e.g. holding the ball between your knees, crunches, planks). Requires a stability ball, 3-5 lbs. dumbbells and mat.
