I could physically jump vertically more than 10 feet in the air with or without use of chi energy? I've been studying martial arts, and I've come to an interest in Ninjutsu. Unfortunately, there are no Ninjutsu dojos in my area (or anywhere close for that matter), and I'm already doing Taekwondo. Any info on how to use chi for jump height, or leg exercises for jump height? I don't know if I already posted this or not, but just in case.
