Sit comfortably in an upright position. Your right arm is lifted in front of you. Your arm is parallel to the floor and your elbow is bent to 90 degrees. Place your left palm on the outside of your right elbow with your left fingers resting on top of your right elbow. Drag your right arm across your body. You'll feel a stretch in the outside of your right shoulder. Relax and return to the starting position. Repeat on the other side.
