Helps you jump if done correctly. What you have to do is keep your knees
locked and just jump off the ground about an inch. You can't bend your
knees at all. You should do it for about 1-2 minutes. If you get better
put a ball in your hands and do it for a longer times. It will work if
you keep it up for 2 months and work hard at it.
