Dumbbell Lateral Raise

You swing the dumbbells up with a hip bounce and shrug, so the traps and momentum lift the weight instead of the side delts.

You go above shoulder height with rotated-back palms, which just shifts the load off the delts.

You let the hands rise higher than the elbows, turning the raise into a forward-arm swing.

You drop the weights back down instead of lowering them for a slow count.

Choose a weight light enough that the reps look identical from first to last; the lateral raise rewards strictness over load.

Lead the movement with the elbows and think of pushing the dumbbells away from you, lengthening the arc.

Tilt the pinky slightly up at the top, as if pouring out a jug, to keep the side delt doing the work.
