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

  1. Attach a D-handle to a low pulley cable machine and lie face down on a flat bench.
  2. Grasp the D-handle with each hand, palms facing down, and extend your arms straight out in front of you.
  3. Keeping your arms straight, raise them out to the sides until they are parallel to the floor.
  4. Pause for a moment at the top, then slowly lower your arms back down to the starting position.
  5. Repeat for the desired number of repetitions.

Tip: Imagine hugging a barrel rather than pushing a weight.

Muscles worked

Primary

Delts · Shoulders

Rear delt flies work the back of the shoulder as the arms swing wide, and the front delt assists on any chest fly.

Secondary

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.

Where it fits in a workout

Flies are an isolation movement for after the pressing or rowing is done. Pair a chest fly with a rear delt fly for a balanced superset.

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
