How to perform
Stand with a light dumbbell in each hand at your sides, with a slight bend in the elbows.
Raise the dumbbells out to your sides until they reach shoulder height.
Lead with your elbows rather than your hands, and keep your shoulders down.
Lower slowly, resisting the whole way.
The side delts respond to control, not load. Almost everyone uses too much weight here.
Common mistakes: swinging the weight with the hips, shrugging the traps, and raising above shoulder height where the traps take over.
