How to do it

Set up

  1. Hinge forward at the hips until your torso is close to parallel with the floor, or lie chest-down on an incline bench.
  2. Hold a light dumbbell in each hand, arms hanging, palms facing each other.
  3. Soft bend in the elbows, held constant.

Perform the rep

  1. Raise the dumbbells out to the sides in a wide arc.
  2. Lead with your elbows, not your hands.
  3. Stop when your arms are level with your torso.
  4. Lower slowly under control.

Common mistakes

  1. Using far too much weight

    The rear delt is small. Heavy dumbbells turn this into a jerky row driven by the traps and lower back.

  2. Squeezing the shoulder blades together

    That recruits the rhomboids and takes work away from the rear delt. Let the shoulder blades stay relatively still and move at the shoulder joint.

  3. Swinging upright to start each rep

    If your torso rises as you lift, you are using momentum. Chest-supported on an incline bench removes the temptation entirely.

How to programme it

15–20reps
45 srest

Go lighter than feels right and focus on the contraction. This is a feel exercise, not a load exercise.

Variations

  • Chest-supported incline rear delt flye: strictest version
  • Cable rear delt flye: constant tension
  • Reverse pec deck: most stable, easiest to overload

Frequently asked questions

Why can I not feel my rear delts?

Almost always too much weight, or squeezing the shoulder blades so the rhomboids take over. Halve the load, lie chest-down on an incline bench, and think about moving your upper arm rather than lifting the dumbbell.
