Hold your right hand out in front of you, keeping it near your waist. Reach your left hand behind your elbow, pulling your right arm to the left and across your chest. If you feel pain in your shoulder, lower your arm until the pain subsides. The goal is to be able to pull your right arm across your chest without feeling any pain. Hold for 30-60 seconds then relax and repeat with your left arm. Repeat 3-5 times.
