Description

Cable rear delt fly focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Adjust the pulleys to the appropriate height and adjust the weight. The pulleys should be above your head.
  2. Grab the left pulley with your right hand and the right pulley with your left hand, crossing them in front of you. This will be your starting position.
  3. Initiate the movement by moving your arms back and outward, keeping your arms straight as you execute the movement.
  4. Pause at the end of the motion before returning the handles to the start position.

Exercise FAQ

What’s a common form error with this movement?

Letting the hips drift or the ribs flare. Keep everything stacked so the core does the stabilizing.

How long or how many reps is enough?

Stop when you can’t keep alignment. Quality beats duration—shorter sets with perfect form are more effective than long shaky holds. Think of it as flye movement done with repeatable, clean reps.

How do I know I’m using my core and not my lower back?

Your torso should stay steady and your lower back shouldn’t pinch or take over. If it does, shorten the range, reduce difficulty, and brace harder. Think of it as flye movement done with repeatable, clean reps.
