Military press - This is a great bang for buck excersize. You can use it to facilitate strength gains specifically or stimulate muscle hypertrophy, or both. All dependent on how you do it, why you do it, and what your goals are. Best thing about compounds; however is almost always no matter what, you'll get both, and you get the added benefit of core stabilization, shoulder stabilization etc. These don't just isolate any one head of the shoulder, but target the whole thing as a whole, surrounding, secondary, tertiary, and stabilizer muscles, etc. In simple terms, it's just a great overall lift in the beginning when you don't really know how to plan, program your lifts, etc. if you got shoulders, instead of worrying about your rear delt, medial, and front, and execution, you can just hit your compounds, balance out your build as you figure the rest out, because it will all come in time my friend.
