Sit upright on an exercise ball with your feet flat on the floor and your core engaged. Raise one arm overhead and bend the elbow so your hand reaches down behind your head toward your upper back. Use your opposite hand to gently pull the bent elbow inward to deepen the stretch. Hold the position while keeping your posture tall and stable, then slowly release and switch sides.
