Setup
- Lie face down (prone) on a flat bench with your chest firmly supported and your head just past the edge.
- Hold a dumbbell in each hand using a neutral grip (palms facing each other).
- Plant your toes firmly on the floor or hook your feet under the bench to stabilize your lower body.
- Let your arms hang straight down toward the floor with a slight, fixed bend in the elbows.
How to do it
- Exhale and raise the dumbbells out to your sides in a wide arc until your elbows are level with your shoulders.
- Focus on leading the movement with your elbows, keeping them aligned with your mid-back.
- Squeeze your shoulder blades together at the top of the movement for a one-second peak contraction.
- Inhale as you slowly lower the weights back to the starting position, maintaining tension on the rear delts.
Form checklist
- Keep your chest glued to the bench throughout the set to prevent swinging.
- Maintain a neutral spine by looking slightly down at the floor rather than straight ahead.
- Ensure the movement occurs at the shoulder joint only; do not change the bend in your elbows.
- Avoid shrugging the weights toward your ears; keep your shoulders pulled down.
Pro tips
- Imagine you are trying to touch the side walls with the dumbbells to maximize the lateral arc and rear delt recruitment.
- Think of your hands as hooks; pull with the back of your shoulders rather than gripping the dumbbells too tightly.
Make it harder
- Add a 2-second isometric hold at the top of every repetition to increase time under tension.
- Perform a slow 3-second eccentric (lowering) phase to maximize muscle fiber breakdown.
