Objective: Increase mobility, stability, and strength between your shoulders and hips. Technique: Lie supine (on your back) on the ball, with your shoulder blades on the ball and your hips raised so that they are parallel to the floor. With your shoulder blades back and down, extend your arms above your chest; place your hands together in a “praying position” or hold a weight plate. Keeping your hips up, turn your shoulders to the right so that they are perpendicular to the ground while your hips stay horizontal. Twist back to the starting position and then to the other side.
