Pinning yourself face down on a bench leaves the rear delts nowhere to hide: no leg drive, no torso bounce, just the cables pulling from the low pulleys as your arms sweep out. It is stricter than both the bent-over and high crossover cable versions, so the weight will be humbling; count that as the point.
How to do the Lying Cable Rear Delt Fly
- Attach a D-handle to a low pulley cable machine and lie face down on a flat bench.
- Grasp the D-handle with each hand, palms facing down, and extend your arms straight out in front of you.
- Keeping your arms straight, raise them out to the sides until they are parallel to the floor.
- Pause for a moment at the top, then slowly lower your arms back down to the starting position.
- Repeat for the desired number of repetitions.
Tip: Imagine hugging a barrel rather than pushing a weight.
Muscles worked
Common mistakes
- Elbows bending as you tire — this turns a fly into a press; set the elbow angle at the start and keep it constant for the whole set.
- Going too heavy — flies are a stretch and squeeze movement, not a strength lift; you should be able to pause at the bottom without the shoulders rolling forward.
- Stopping short of the stretch — let the arms open until you feel the chest or rear delts lengthen, then bring them back under control.
- Not squeezing at the finish — the last few inches are where the muscle shortens most, so hold the contraction for a count before opening again.
Sets, reps and where it fits
| Goal | Sets × reps | Rest |
|---|---|---|
| Muscle growth | 3–4 × 10–15 | 60–90 s |
| Endurance / finisher | 2–3 × 15–20 | 45 s |
| Strength | Not ideal — pick a compound lift for the same muscle | — |
Flies are an isolation movement for after the pressing or rowing is done. Pair a cable crossover with a cable rear delt fly on the same station, or dumbbell chest flies with dumbbell rear delt flies on the same bench.

Frequently asked questions
What muscles does the Lying Cable Rear Delt Fly work?
The Lying Cable Rear Delt Fly primarily works the delts. It also involves the traps and rhomboids, which assist the movement and stabilise the joints.
Is the Lying Cable Rear Delt Fly good for beginners?
It is rated intermediate, so it suits people who already train regularly. Beginners can still do the Lying Cable Rear Delt Fly with light load and a spotter or coach watching the first few sessions; if it feels awkward, pick an easier variation from the alternatives below first.
What can I do instead of the Lying Cable Rear Delt Fly?
If you cannot do the Lying Cable Rear Delt Fly, try the Incline Bench Dumbbell Rear Delt Fly, the Incline Bench Rotating Grip Dumbbell Rear Delt Fly or the Seated Dumbbell Rear Delt Fly. Each of them trains the delts through a similar movement, so you can swap them in without changing the rest of the workout.
How many sets and reps should I do?
It depends on your goal. For the Lying Cable Rear Delt Fly, a sensible starting point is muscle growth: 3–4 × 10–15 with 60–90 s rest; endurance / finisher: 2–3 × 15–20 with 45 s rest. Do it after your compound lifts. It is a finishing movement, not the main event.
