5 Most Effective Shoulder Building Exercises
 

Military Press. This exercise has been a staple of great workouts for decades on end.
Push Press. Very similar to the military press, but utilizing more of an Olympic lifting-style explosiveness.
Bench Press. Yes, you read that correctly. The bench press is an amazing front delt builder. In fact, if your chest day involves several pressing movements there's a good chance you won't need any direct front delt work on shoulder day.
Seated Behind The Neck Press. Go no deeper than arms perpendicular to the floor, and this is a rock solid choice.
Seated Dumbbell Press. A little easier on the shoulders for many because the dumbbells can be placed in a more natural position.
