How to do it

Setup

  • Set an incline bench beside a low-to-mid cable
  • Brace the chest on the pad
  • Hold the cable with the far arm
  • Start with a soft elbow and shoulder reaching across

Execution

  • Sweep the upper arm out and back
  • Keep the torso on the bench
  • Stop before the shoulder blade squeeze turns it into a row
  • Return slowly across the body

Common Errors

  • Rotating off the bench
  • Bending the elbow into a row
  • Shrugging
  • Pulling past the controllable shoulder range

Cues That Work

  • Chest stays down; sweep the elbow wide; rear delt finishes before the torso turns

No-Fly Zone

Avoid loads that twist the torso or turn the rep into a row.

Programming

Sequence priority

Late

Supported unilateral isolation fits after compound pulling and exposes side-to-side control without much systemic fatigue.

Progression

Model — Double

Fallback model — Density

Match bench position, arm path, and finish on both sides; add reps before the smallest cable increase.

Best program fit

Pull

Load increments

Standardthe smallest cable increment
Smaller incrementadd reps or a one-second finish
Larger incrementone full stack step after both sides match

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.

  1. Step 1

    Setup tweaks

    Change cable height and bench angle until the cable follows the upper-arm arc.

  2. Step 2

    ROM / tempo / bias

    Use a one-second finish and a three-second return.

  3. Step 3

    Implement swap

    Reverse pec deck or standing dual-cable reverse fly.

Substitutions

Approved fallback

Reverse pec deck or standing dual-cable reverse fly.

The Evidence

This setup improves stability and unilateral control. It does not eliminate upper-back contribution or prove superior rear-delt growth versus every other reverse-fly path.
