The rotator cuff is four small muscles that stabilize your shoulder. They are often weak and tight, especially in desk workers. These exercises build the rotator cuff strength and mobility that prevents shoulder problems. Get personalized mobility routines: Start your 14-day free trial Why This Matters The rotator cuff keeps your shoulder centered in its socket during movement. Weak or tight rotator cuff muscles allow improper joint mechanics, leading to impingement, tendinitis, and tears. Healthy rotator cuffs mean healthy shoulders.
