Reverse Pec Deck
Reviewed by Bryan Cortez, MS
Lead with the elbows, stop before the traps take it — small muscle, light weight, high reps.

Setup
- Chest on the pad, handles at shoulder height, soft elbows.
Execution
- Open the arms back in an arc leading with the elbows/pinkies, squeeze the rear delts, and control the return. Don't shrug or let the mid-traps take over.
Common Errors
- Bending the elbows to press it instead of arcing it open
- Shrugging / letting the mid-traps take over
- Going so heavy the range shrinks
- Leading with the hands instead of the elbows
Cues That Work
- Lead with the elbows; reach wide, not back; keep the shoulders away from the ears
No-Fly Zone
under 10 reps (heavy turns it into a mid-trap row)
Programming
Sequence priority
Late
Tiny muscle, low fatigue — a finisher; rear delts recover fast and like frequency.
Progression
Model — Triple
Fallback model — Double
Triple progression: add reps toward ~25, then a pin or micro-plate.
Best program fit
Pull, Push, Upper
Load increments
If it hurts
Pain is information, not a challenge to push through. Stop the set if pain is sharp, worsening, or changes how you move. These are exercise-selection options, not medical diagnosis or rehabilitation advice.
Work down this list in order. Stop at the first change that removes the pain.
Step 1
Setup tweaks
Handle height; grip (pronated emphasises the rear delt); seat height.
Step 2
ROM / tempo / bias
Pause and squeeze; slow eccentric; lead with the pinky to cut trap involvement.
Step 3
Implement swap
Cable reverse fly, face pull, or bent-over dumbbell reverse fly.
Substitutions
Approved fallback
Cable reverse fly, face pull, or bent-over dumbbell reverse fly.
Compare all shoulders optionsThe Evidence
Isolates the rear delts. Does NOT build the side or front delt, or any pressing strength.
