External Rotation with Cable
The cable version of shoulder external rotation: pulley set at elbow height, elbow pinned to the ribs, forearm swept outward against constant tension. Unlike a dumbbell it loads every degree of the range equally, and unlike a band it lets you add 1-2 kg at a time and actually log the progression.
Own the movement
Set up first, then execute. Every cue below is something you can check on your next set.
Before the first rep
- Set the pulley to the height of your elbow when your arm hangs at your side, and clip on a single handle.
- Stand side-on with the working arm on the outside, far from the machine, roughly a metre away.
- Reach across your body and take the handle with the working hand, palm facing in.
- Trap a rolled towel between your upper arm and your ribs to hold the elbow at your side.
- Set the elbow at a hard 90 degrees, forearm across your stomach, and take the slack out of the cable before rep one.
Every rep
Breathing & tempo — Exhale on the outward sweep, inhale on the return. Two seconds out, one second held, three seconds back against the stack.
Sets, reps & load
Where to start, and what to change when it stops being hard.
Start on the lightest plate — often 2.5-5 kg on a standard stack — and expect to stay in single digits for a long time. Fifteen reps per side with the elbow pinned, no shrug and a one-second hold at end range is the marker for adding the next increment. Adding a plate before that just recruits the lat.
What goes wrong
The errors that show up most often, and the cue that fixes each one.
Move the pin down to elbow height before every set. A high pulley pulls the elbow off your ribs and turns the movement into an awkward rear-delt fly.
Take it back to the lightest plate on the stack and add 1-2 kg only when 15 reps per side are clean with a one-second end-range hold. Cuff work is not judged by the pin position.
Set your shoulder blade down and back before the rep and keep the neck long. If the shrug still happens, cut the weight in half and slow the movement down.
Step out until the stack stays lifted for the whole rep. Slack means the muscle stopped working, which is exactly the phase you were trying to load.
Why bother
A cable pulls with the same force at the start of the arc as at the end. A side-lying dumbbell gives you almost nothing at the bottom and everything at the top; a band gives you the reverse-ish, ramping towards end range. For a muscle group this small, even tension across the whole sweep is the most efficient way to accumulate work.
The other advantage is the weight stack. Cuff progress happens in 1-2 kg steps, and band colours and dumbbell racks often jump far more than that. Being able to add the smallest plate is what turns rotator cuff work from a ritual into something you can actually progress.
Where it fits
End of an upper-body day, 2-3 sets of 12-15 per arm, two or three times a week. It pairs naturally with face pulls and rear-delt work in a single block of posterior shoulder training. Keep it after your pressing, not before — a pre-fatigued cuff makes a heavy bench less stable, not more.

Asked and answered
What height should the cable be set to?
Level with your elbow when the arm hangs at your side. That makes the line of pull horizontal and square to the rotation. Set it higher and the cable drags the elbow away from the ribs; set it lower and it pulls the arm down and forward.
Should I also train internal rotation?
Rarely as a priority. Every press, row, pulldown and chin-up already loads the internal rotators heavily, so the external side is the one that needs deliberate work. Direct internal rotation is worth adding only if a clinician has identified a specific weakness.
How do I know the cuff is doing the work and not my rear delt?
The elbow. If it stays welded to your ribs at 90 degrees and the forearm stays level, the rotation has to come from the cuff. As soon as the elbow lifts away from the body, the rear delt has taken over and you are doing a bad fly.
Is it worth doing this if my shoulders do not hurt?
Yes, and that is the best time to do it. Six minutes a week keeps the external rotators contributing to a joint that everything else in your programme trains in the opposite direction. It is far cheaper than rehabbing the shoulder later.
