The Jump Manual is a program that teaches people how to jump higher and was written by Jacob Hiller.  Now Jacob might not have a degree in anything related to jumping but through his own experiences he has designed a program that will increase anyones vertical leap.

Jumping isn’t as hard to achieve as it once was.  People are now adding 10 inches to their vertical in a matter of weeks so why not be one of those people?  All you have to do is train your muscle properly and you will have great results and become a different type of athlete.

Are you sick of being picked last for basketball or volleyball?  Well it’s time you learn to jump higher fast so that you will become the dominating player on the court.
