I have a friend who has big shoulders and the only exercise he does for his shoulders is the military shoulder press---the two versions of it, the behind neck one and the front one.I wonder if only doing shoulder presses covers the entire area of your shoulders, the three deltoids?Thanks.
You could do thator to get faster results i would suggest deadlifting
Military press is a great exercise for front delts. Behind the neck press puts the shoulders in a bad position and can cause joint trouble over time, avoid them. Side laterals are best move for side delts. Most pulling moves - bent rows, pull/chinups. lat machine, etc - work rear delts.
