Do Olympic lifting --> power cleans and power snatches
but to be able to jump a reasonable height, make sure you can squat
a reasonable amount of weight first (at least 2x body weight) ...
so don't neglect the normal weights training routines - back
squats, front squats, split squats, etc
also ... do lots of lower body plyometrics as well
another thing that'll help a lot would be kettlebell training - eg.
KB swings, snatches and push press
