Begin by kneeling on the ground, shoulders relaxed and hands resting atop a resist-a-ball.  Slowly roll ball forward, allowing your body to be suspended, and your entire core muscles to support your weight, until a 45-degree angle is reached.  At that point, without bending your hips or back, keeping core muscles engaged, pull in and return to starting position.
