The lateral deltoid raise (pictured below) is a great exercise to work the shoulders, and more specifically, the side deltoids. But many times it is done ineffectively.
In order to make the exercise as effective as possible, the first thing you need to remember is to keep a slight bend in your elbow; you don’t want your arm to be locked straight.
Secondly, and more importantly, when performing the movement you want your pinky to be higher than the rest of your hand. Basically you want your hand tilted forward like you’re pouring someone a drink (in which case the pinky is the highest part of the hand) in order to effectively work the muscle group.
