One-Arm Rear Delt Raise


Differentiation: Mechanics

This variation of a row is unique. Here is how: you perform reps with one arm for a full set, | then switch the dumbbell to your other arm. Working individual sides allows you to intently focus on one rear deltoid at a time, increasing the overall definition in your rear deltoids. Since you kneel on the bench | and only working one side at a time, | you must engage your entire core to counterbalance the weight on your other side. Using your core increases the overall strength of your core.

8) When all reps are finished, switch the dumbbell to your other hand. Then, perform the same number of reps using your other arm.


Proper Form

Pay special attention to following proper form by...

1092-mm-391.png
Try not to swing the dumbbells up (only use your shoulders).

Keep your elbow above the hand at all times, which will keep constant tension on the rear delt and provide the most benefit.

Keep your head up and back flat.

Keep your upper body stationary. That way your rear delts will do all of the work and receive the utmost benefit.
