Muscle Strengthening Exercises – These exercises improve shoulder muscle strength, relieve pain when done gently, and help to prevent further injury or problems. The level of resistance or weight size can be increased gradually. Some Mild soreness is OK with these exercises, but stop them if sharp or severe pain occurs. Perform 15 to 20 repetitions of each exercise described fairly slowly to avoid strain and jerking, holding for one to two seconds at full extension for each exercise. You can use hand weights or resistance bands for these exercises.
