Shoulders
Cable External Rotation
A precise isolation movement designed to improve rotator cuff stability and bulletproof your shoulder health.
How to perform.
Follow the sequence — setup is half the lift.
Set the cable pulley to elbow height and attach a single D-handle grip.
Stand perpendicular to the machine and grasp the handle with your far hand, keeping your elbow tucked against your side at a 90-degree angle.
Place a small rolled towel between your elbow and your ribs to ensure the upper arm remains stationary throughout the set.
Rotate your forearm away from the machine as far as comfortably possible while keeping your elbow pinned to your side.
Pause for a second at the peak of the contraction to feel the tension in the back of your shoulder.
Slowly return the handle to the starting position across your midsection under full control.
Complete the desired repetitions then repeat the process with the opposite arm.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Allowing the elbow to drift away from the torso during the rotation.
- Using excessive weight that forces the torso to twist to complete the rep.
- Performing the movement too quickly and relying on momentum rather than muscle tension.
- Restricting the range of motion by not bringing the arm fully across the body.
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
