Constant tension from bottom to top.
The cable keeps tension even at the bottom, so lead with the elbow and don't let it go slack.
Standing side-on with the cable running across your body means the side delt is loaded from the very bottom of the raise, the exact zone where a dumbbell version has nothing to offer. One arm at a time keeps the reps strict and lets you watch the working delt carry the handle to shoulder height. It earns its place as the constant-tension lateral raise, ideal for building side delt width without heaving weight around.
Tension. A dumbbell is almost weightless at your side and heaviest at the top, while the cable across your body loads the delt through the entire arc, bottom included.
Shoulder height, no higher. Above that the traps take over and the side delt clocks off. Pause at the top, then fight the handle back down slowly.
Leading with the elbow keeps the movement in the shoulder and stops the hand and wrist steering the rep. Think about pushing the elbow out and up, not lifting the handle.
