Single Arm Cable Rear Delt Fly
The single arm cable rear delt fly is an isolation exercise that targets the posterior deltoid and upper back. Using a cable allows for constant tension throughout the movement and training one side at a time helps correct muscle imbalances and improves mind-muscle connection.

How to do the Single Arm Cable Rear Delt Fly
- 01
Set a cable pulley to shoulder height and attach a single-handle grip.
- 02
Stand side-on to the machine and grab the handle with the hand furthest from the tower, crossing in front of your body.
- 03
Take a small step back, stagger your stance, and bend slightly at the hips for stability.
- 04
With a slight bend in the elbow, pull the handle out and back in a wide arc until it is in line with your shoulder.
- 05
Squeeze the rear delt at the peak of the movement without shrugging.
- 06
Slowly return the handle across your body under control and repeat for reps before switching sides.
Cues that matter
- Keep the elbow slightly bent and locked in that position so the rear delt does the work, not the triceps.
- Use light weight and focus on contracting the rear delt rather than chasing heavy loads.
- Avoid twisting the torso to generate momentum - the movement should come from the shoulder.
