They were both fairly good athletes to begin with. I don't think either of them followed the programs, just kinda ran around in them and shit.
The one kid used them during track practice only, he was the one who made the most improvement and went to states in high jump. I remember him telling me about(and seeing him) limping around at school for quite a while when he started using them. He said even the instructions said to walk in them for a little bit a day for the first week or two so you don't injure yourself.
I respond well to jumping/ jump training, I remember when I was in Volleyball I would start out the season barley able to nick the rim, but then by the end of the season, would be able to put a volleyball down and easily hang from the rim jumping off 2 feet and grabbing with 2 hands
. This is more just for fun for me to do, I probably won't start messing with it for another month or so, till golf starts winding down. I'll keep ya'll posted
