How to do it

  1. 1Hold a pair of dumbbells and hinge forward with a soft bend in your knees.
  2. 2Let the weights hang below your shoulders with a slight bend in the elbows.
  3. 3Raise the dumbbells out to the sides in a wide arc until your arms are about in line with your shoulders.
  4. 4Pause briefly while squeezing the rear delts and upper back.
  5. 5Lower the weights back down under control and repeat.

Tips & tricks

  • Lead with the elbows and think about moving wide, not backward like a row.
  • Keep the neck relaxed and shoulders away from the ears.
  • Use lighter weights than you think so the rear delts stay in charge.

Common mistakes

  • Turning the movement into a row by pulling the elbows too far back.
  • Shrugging the shoulders up toward the ears.
  • Using momentum and torso swing to lift the dumbbells.
