A good exercise for strengthening the shoulders and back muscles.
- Sit with good posture on the stability ball. Hold onto one end of the exercise band and have the middle of the band under the opposite foot. You could also tie the band around something low and sturdy.
- Pull your hand diagonally across your body and up toward the ceiling, keeping your elbow slightly bent and avoiding shrugging your shoulders. Watch your hand throughout this movement.
- Continue pulling the hand across and up toward the ceiling. As you near the end of the movement twist your torso slightly so that you can reach the arm just slightly behind your body.
