External Rotation with Cable
A standing cable exercise that rotates the forearm across the body outward, similar to a backhand motion, to train shoulder stability. It suits beginners adding shoulder health work to their routine.
How to do the external rotation with cable
- Set a cable to elbow height and stand with your side facing the machine.
- Grip the handle with the far hand and press your elbow firmly into your side.
- Position your forearm across your torso with your elbow bent to a right angle to start.
- Rotate your arm outward in a backhand motion, keeping your elbow pinned to your side.
- Return slowly to the starting position, keeping the movement controlled throughout your set.
Original library instructions (4 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.
Common mistakes
- Letting the elbow drift away from the body, which removes the isolation this exercise is meant to provide.
- Using a cable weight too heavy for smooth, controlled rotation.
- Rushing through the return phase instead of lowering back with control.
Sets and reps by goal
| Goal | Sets, reps and rest |
|---|---|
| Strength | 3 sets of 10 to 12 reps per arm, 45 to 60 seconds rest |
| Muscle | 3 sets of 12 to 15 reps per arm, 45 seconds rest |
| Endurance | 2 to 3 sets of 15 to 20 reps per arm, 30 seconds rest |
Ranges, not prescriptions. Start at the low end and add a set or a rep when every set feels controlled.
Tips
- Hold a small pad or rolled towel between your elbow and side to help keep the elbow still.
- Keep the resistance light so you can focus on a clean rotation rather than muscling the weight through.
