Rotary Cuff Shoulder Exercises
The group of small muscles and tendons responsible for connecting your upper arm to your shoulder and stabilizing your shoulder joint are collectively called the rotator cuff. Heavy lifting and repetitive arm movements can injure these muscles, causing pain, stiffness, limited range of motion in the shoulder and shoulder weakness, says MayoClinic.com. Regularly exercising the muscles of your shoulder and rotator cuff reduces your risk of developing a rotator cuff injury.
