Strengthening exercises help make your injured shoulder more stable by making the muscles that support your shoulder stronger. To warm up, do flexibility (stretching) exercises first.
With feet and hands shoulder-width apart, place your palms on the wall, standing about an arm’s length away.
Keeping your knees straight and heels on the floor, bend your elbows and lean forward as far as you comfortably can. Your elbows should be pointing downward. Then push away from the wall to the starting position. Repeat.
Work up to 15 wall pushups.
Note: Wear shoes that keep you from slipping.
