Cheers Tom no worries at all, as for plyos in gym we will do jump ups to a box, a limted amount of depth jumps either back on to a box or for height or over a hurdle or long jump for distance, we also do a lot of knees to feet jumps both loaded and unloaded also onto rubber mats for height, outside we do a lot of bounding, hopping and 2 feet jumps for distance and time, if you are unfamiliar with any of these there are dozens of videos on you tube, my all time favourite is the Werner Gunthor video, go well, ashley
