Cable Seated Shoulder Internal Rotation
Cable Seated Shoulder Internal Rotation Exercise Description
The cable seated shoulder internal rotation trains the shoulder’s internal rotators with the arm by your side and the elbow bent to 90 degrees. It primarily targets the subscapularis, with assistance from the pectoralis major, latissimus dorsi, and teres major as secondary internal rotators. The cable provides continuous tension and a consistent line of pull, helping you focus on smooth humeral rotation without compensations. Seated positioning encourages a neutral spine and quiet scapula, emphasizing control over range. Work through a comfortable motion while keeping the upper arm anchored and the wrist neutral for efficient, shoulder-friendly mechanics.

How To Do The Cable Seated Shoulder Internal Rotation Exercise
‘- Set a single handle on a low pulley at roughly elbow height when seated.
– Place a bench perpendicular to the machine and sit sideways with the working shoulder closest to the cable.
– Feet flat, ribs stacked over pelvis, neutral spine; gently set the shoulder blade (slight retraction and depression).
– Grip the handle with the working hand, palm facing inward. Elbow at 90 degrees, upper arm resting lightly against your torso. Optional: hold a small towel between elbow and side to keep position.
– Start with the forearm rotated outward (away from your body) so the cable has light tension; keep the wrist straight.
– Without moving your elbow or torso, rotate your forearm across your abdomen to internally rotate the shoulder.
– Pause briefly, keeping the shoulder down and the scapula quiet (no shrugging or protraction).
– Reverse the motion under control until the forearm returns to the start without the elbow drifting.
– Throughout: maintain steady breathing, a neutral wrist, and avoid trunk rotation or leaning.
Cable Seated Shoulder Internal Rotation Tips
‘- Set the cable handle at about elbow height when you’re seated to keep the line of pull consistent.
– Sit sideways with the working shoulder closest to the cable, feet flat and ribs stacked over your pelvis.
– Gently set your shoulder blade with slight retraction and depression before you start.
– Keep your elbow bent to 90 degrees and resting lightly against your torso; use a small towel if needed to maintain this contact.
– Start with your forearm rotated outward so the cable has light tension while keeping your wrist straight.
– Rotate your forearm across your abdomen without letting your elbow move away from your side or drift forward/back.
– Keep the shoulder down and the scapula “quiet,” avoiding shrugging or letting the shoulder roll forward.
– Reverse the motion under control, returning only as far as you can without elbow drift or torso movement.
– Maintain a neutral spine, avoid trunk rotation or leaning, and keep your breathing steady throughout.
Cable Seated Shoulder Internal Rotation Beginner Introduction
The cable seated shoulder internal rotation is a cable-based isolation move for the inner rotator cuff, performed with the arm resting by the side and the elbow bent to a right angle. Seated positioning near a low pulley creates a stable base, while the cable’s steady resistance guides a smooth turning motion of the upper arm. This setup highlights the muscles deep in the front of the shoulder, with support from the chest and upper back, as the arm rotates inward.
During this exercise, the upper arm stays gently against the torso while the forearm sweeps across the midsection in a controlled arc. The trunk remains upright and quiet, encouraging a natural spine position and a steady shoulder blade rather than extra shrugging or twisting. The emphasis is on calm, deliberate rotation within a comfortable range, with the wrist held in line with the forearm and breathing kept regular. This creates a focused way to work the shoulder’s internal rotators under constant load, with attention on smooth mechanics and shoulder-friendly control.
