I call them overhead presses. The other names just don't make sense to me. Im not in the military and I do bench presses, not chest presses.

Im also gunna agree with Alco on this one. Push presses will make your shoulders grow something nasty. The only reason why i do seated presses is because my gym has a stupid rule about have the bar over your head while standing. Ive been asked to leave before for not complying.

As far as hypertrophy, Im gunna cop out and take the "waterbury approach to this one". Ive really never experienced greater amounts of hypertrophy with high reps, Lower reps and a fast speed will cause more growth than moderate weight at higher reps. You wanna grow, work the largest muscle fibers and recruit the most fibers you can, in other words. lift heavy, lift fast.
