Steps
- Adjust the cable to the same height as your elbow. Stand with your left side to the band a couple of feet away.
- Grasp the handle with your right hand, and keep your elbow pressed firmly to your side. We recommend you hold a pad or foam roll in place with your elbow to keep it firmly in position.
- With your upper arm in position, your elbow should be flexed to 90 degrees with your hand reaching across the front of your torso. This will be your starting position.
- Execute the movement by rotating your arm in a backhand motion, keeping your elbow in place.
Tracking it in OneRep
Add the external rotation with cable to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.
Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.
Where the instructions come from
The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
