How to Perform

Adjust incline bench to 45 degrees. Lie face-down with chest supported, feet flat on floor, holding dumbbells with neutral grip hanging straight down.

  2. Exhale and raise dumbbells out to sides in wide arc, leading with elbows.
  3. Squeeze shoulder blades together at top.
  4. Pause briefly to feel contraction in rear delts.
  5. Inhale and lower dumbbells slowly to start position.
  6. Maintain slight elbow bend throughout.
  7. Repeat for reps.
