military press is where your forearms point straight up. So wouldn't that work the front deltoids?
I think if you forearms point down (elbows out) you work your rear deltoids. forearms forwards (elbows back) you work your mid deltoids. Forearms up (elbows down) you work your front deltoids. So if a guy does lateral raises, and goes over their head, and rotates their palms together like jumping jack, then he just worked mid deltoids and then his front deltoids. But if he keeps his palms down as he goes over his head, he could damage some stuff in his shoulder area. Correct me if I'm wrong on this.
