How to do the Dumbbell Rear Delt Raise

ShouldersDeltsDumbbellIntermediate

The dumbbell rear delt raise is one of the most effective isolation movements for building the posterior deltoid, a muscle that directly improves shoulder width, posture, and pressing strength. Mastering this lift separates athletes who look complete from every angle from those who only train what they can see in the mirror.

Step-by-step

  1. Hinge at the hips until your torso is nearly parallel to the floor, letting the dumbbells hang directly below your shoulders with a soft bend in your elbows.
  2. Initiate the movement by driving your elbows out and up to shoulder height, leading with the rear delts rather than your hands.
  3. Pause briefly at the top with your arms parallel to the floor, squeezing the posterior deltoids before controlling the descent.
  4. Lower the dumbbells slowly over two to three seconds back to the start position, maintaining your hip hinge throughout the set.

Common mistakes

  • Using too much weight and turning the movement into a body-English shrug — drop the load and keep your traps out of the lift by retracting your shoulder blades only slightly, not excessively.
  • Letting the torso rise during the set, which shifts stress off the rear delts and onto the upper back — lock your hip hinge position before the first rep and hold it for the entire set.
  • Bending the elbows too deeply to make the weight feel lighter, which reduces the lever arm and unloads the target muscle — maintain a fixed, slight elbow bend as if your arms are rigid arcs.

Pro tip — Rotate your pinkies slightly higher than your thumbs at the top of each rep, as this internal shoulder rotation more fully engages the posterior deltoid fibers and delivers a sharper, more productive contraction.
