can anyone give some cues for doing plyos when jumping over 6-8 inch blocks or cones.An example of the drill will be one when the athlete is doing a two footed jump over cones or blocks. where are shoulders over the hips or directly under. some of the athletes dont seem to get any extention,there leaning forward .
and when doing plyos where the athlete is doing hops over a line ,some of the kids sound like their killing roaches,they seem to be stomping with the toes.
and when going over boxes or blocks that are higher 1-1/12 feet where are the shoulders in relationship to the hips. and should the athlete ever hop over anything that high
