How to make my shoulder stronger?!

Best Answer - Chosen by Voters

Here are a few sites that discuss physical therapy for the shoulder:

PURPOSE:
To relax the muscles in your shoulder. To relieve pain and increase motion.
POSITION:
Lie on your stomach close to the edge of the bed. Let your weak arm hang over the edge of the bed. Relax your shoulder, arm and hand. Let your shoulder blade relax and drop down.
ACTION:
Slowly and gently swing your arm forward and back. Do not use your neck muscles. Relax them. It might be easier to have someone else gently start swinging your arm. As pain decreases, increase your swing. Initially arm swing should begin at 15 degree angles and eventually progress to 30-45 degree angles as pain subsides within time. The duration of the swing should initially be 15 seconds and eventually progress to 3-5 minutes.

PURPOSE:
To relax the muscles in your shoulder, in order to relieve pain and to increase motion.
POSITION:
Stand and hold onto a sturdy chair with your good arm. Bend forward at the waist and bend your knees to help protect your back. Relax your weak arm, let it hang limp. Relax your shoulder blade and let it drop.
ACTION:
Keep your shoulder relaxed and use body motion to swing your arm in small circles. Stand tall and relaxed. Repeat motion and change direction of circles. The duration of the circles should initially be 30 seconds and eventually progress to 3-5 minutes.
