Question
hey
  can u tell me what r the major muscles involved when spiking the ball? i'd like to work on them a lot.
   thanks

Answer
upper body strength is important. abs, back, and arms...very important. It is important to work the muscles evenly to avoid possible injuries. You should try to work with a trainer to insure you are working all of the muscles properly. A bad strength program is worse than no program at all. Injuries will come from not working out properly.
