Pilates: Footwork on Ball

Lie faceup, arms by your sides, palms facing down. Bend your knees and place the balls of your feet on top of the ball, heels together and toes pointing slightly outward in a small V shape. Engage your core and contract your glutes to lift your hips an inch off the floor, then roll the ball away from you until your heels are on the ball. Pause, then bend your knees to roll the ball back to the starting position. That's one rep.
