Shoulders Exercise · Cable
Cable Seated Shoulder Internal Rotation
Cable internal rotation trains a small but important rotator cuff muscle that almost no compound lift targets directly, rotating the forearm inward against resistance with the elbow pinned to the side. It's typically programmed for shoulder health and injury prevention rather than size or strength, often alongside its counterpart, external rotation. Keeping the elbow fixed against the body is what isolates the rotator cuff instead of turning it into a shoulder press.

- Keep your elbow slightly bent and your shoulder blades pulled back and down.
- Slowly rotate your arm inward, bringing the cable handle toward the center of your body.
- Pause briefly at the end of the movement, then slowly return to the starting position.
- Repeat for the desired number of repetitions, then switch arms.
