Jump Manual program was designed by Jacob Hiller, which helps the professionals and athletes in increasing their vertical jump. Jacob Hiller has been a professional quickness and jump trainer for both the Olympians and the NBA players; therefore he seems to know what he is talking about. In the words of Jacob Hiller, Jump Manual is the last word in high jumping and a complete program that incorporates everything you will need in order to jump higher than the rest of your competitors. This program also helps the athletes in improving their quickness because jump and quickness go hand in hand.
