How to Perform

  1. Hinge forward at the hips about 45-60 degrees, or lie face down on an incline bench
  2. Let dumbbells hang straight down with a slight elbow bend
  3. Raise arms out to the sides in a wide arc, squeezing your rear delts at the top
  4. Hold for 1 second at the top
  5. Lower with control over 2-3 seconds

Tips

  • Keep a slight bend in your elbows locked throughout — straightening your arms shifts work to the traps
  • No dumbbells? Reverse pec deck, cable reverse flys, or resistance band pull-aparts all hit the rear delts
  • Use a slow 2-1-3 tempo (2 up, 1 squeeze, 3 down) — rear delts respond better to control than heavy weight
  • Lifting too heavy and using body momentum is the most common mistake — rear delts are small, so go lighter than you think
  • Focus on squeezing the muscle at the back of your shoulder — you should feel a burn right behind the shoulder joint
