Hold a handle attached to a low cable with one arm and the unloaded shoulder facing the machine. Keeping the trunk braced tightly, lift the handle up to the side with a straight arm to above shoulder height, then lower again under control. Both arms can be done together if you have access to a double cable stack.
 
Purpose
The cable lateral raise strengthens the lateral and anterior delts. The cable variation keeps a more continuous level of tension on the shoulder throughout the range of motion than the dumbbell variations.
 
Programming
Generally sets of 8-20 reps are appropriate.
