The jump manual is a program created by Jacob Hiller who is a jump trainer. It is a manual jump increasing program for athletes who need at the very least a 10 inch gain. The program concentrates on little known physical exercises that increase the vertical jump through strength and speed. The good thing is if you do not gain at least 10 inches you get double your money back. 

The jump Manual contains important nutrition for athletes especially as their bodies metabolize faster thus requiring different diets. It focuses on nine different elements of vertical jumping that coaches often fail to mention. 

In only twelve weeks any athlete can develop a vertical jump explosion of 10 inches. The capabilities, strength and performance are developed and build on cumulative improvements for the athlete. The athletes are also taught how to train to maximize and improve balance, flexibility form and confidence in their sports.
