Do JUMPSOLES really work???

[emmmmy]

I had a pair when I was 16, but i never fully committed to the program. Has anyone actually used them and seen results
They claim to add 5-15inches to your vertical jump

I had them back in the day they worked a little but doing simple machine workouts in the gym will give you better results without the knee issue these are known to cause.

how about http://www.vertical-jump-program.com/ anyone tried this?

people just need to work on their body composition, jumping, olympic lifts, sprints, and explosions. everything else is irrelevant.
