Why lean away from the support?

Leaning shifts the line of pull so the lateral deltoid is loaded even at the bottom of the rep, which removes the dead zone you get with a standard standing lateral raise.

How heavy should I go?

Light to moderate. A load you can control for 12 to 20 clean reps per arm works best for this isolation movement.

Can I do this on a cable machine?

Yes. A low pulley gives even more constant tension, but the dumbbell version is easier to set up and feels more natural at the top.

How to Perform

Stand next to a squat rack or sturdy upright and grip it with one hand at chest height.
Hold a light dumbbell in the opposite hand with a neutral grip.
Lean away from the support until your arms are straight and your body is at roughly a 20 to 30 degree angle.
Brace your core and keep a slight bend in the working elbow.
Raise the dumbbell out to the side in a wide arc until your arm reaches shoulder height.
Pause briefly at the top and keep your wrist level with your elbow.
Lower the weight slowly under control back to the fully stretched position.
Complete all reps on one side before switching arms.

Common Mistakes

Swinging the body away from the support to generate momentum
Shrugging the shoulder so the upper trap takes over the lift
Using too much weight and cutting the range of motion short
Letting the wrist rise above the elbow and turning it into a front raise
Dropping the dumbbell quickly instead of controlling the negative
