Behind the neck presses are bad bad bad, IMO. Dumbell shoulder presses put your arms in a very similar position, but don't require you to bend your neck forward at the bottom of the movement.
If you want weight exercises to help you hit harder, try pullovers (especially machine pullovers), tricep extensions, forearm/wrist curls, and ab work. I won't get into jumping exercises, other than to say that the higher you jump, the further in front of you you can hit (i.e., make contact with) the ball.
I couldn't disagree more. All hitting power in volleyball is in front of the body. Watch the best hitters and you'll see that their arm never goes behind their head. Even if it looks like they're swinging from behind, they're just arching their back so they can get more of their abs into it.Ivan Danko said:Also for volleyball i would say these are almost a must becuase of serving and spiking movements. In these you come from the posterior anyway i think by not diong them you are setting yourself up for injury.
