Which exercise strengthens the rotator cuff?

• A. Bent Arm Internal/External Rotation with an anchored resistance band in hand and elbows tucked into body
• B. Push Up
• C. Lat Pulldown
• D. Upright Row

Answer: (A)

Strengthening the rotator cuff means training the small shoulder muscles that rotate the humerus while keeping the shoulder blade stable. The most effective option uses a resistance band anchored to a fixed point and performed with the elbow tucked into the body, allowing controlled internal and external rotation of the shoulder. This setup isolates the rotator cuff muscles—the subscapularis for internal rotation and the infraspinatus/teres minor for external rotation—and trains them to work together to keep the humeral head centered in the socket during arm movements. Keeping the elbow close to the body reduces momentum and emphasizes the cuff, while using light to moderate resistance and a slow tempo builds endurance and stability without stressing the joint. Push-ups mainly challenge the chest and triceps and involve more shoulder extension and scapular motion rather than isolating the rotator cuff. Lat pulldowns target the large back muscles and can place more load on the shoulder complex rather than strengthening the cuff in isolation. Upright rows engage the deltoids and traps and can risk shoulder pinch or improper alignment, not ideal for directly fortifying the rotator cuff.
