National Academy of Sports Medicine answeredLie on your side on a stability ball with the ball placed under your hips and our feet anchored against a wall. Extend your legs, placing them in a staggered-stance position with your bottom foot placed slightly in front of the other. Cross your arms over your chest, draw-in your navel, contract your glutes and tuck-in your chin. Raise your upper body into a side crunch position and slightly rotate your chest toward the ceiling. Return to the starting position and repeat, rotating in the opposite direction.
