Jeet Kune Do
Jeet Kune Do (way of the intercepting fist) is a martial art created by Bruce Lee during the 1960s. Neither a system nor a method, Bruce Lee didn’t consider his art a style, but an aggregate of principles for developing the martial mind and body.
Jun Fan Gung Fu
Bruce Lee continued to develop in the martial arts, but what he was teaching was no longer Wing Chun. So he named it Jun Fan Gung Fu, named after himself, as it was his system.
Jeet Kune Do’s foundation lies in wing chun theory, but Bruce Lee also borrowed from other kung fu styles: taekwondo, wrestling, fencing and Western boxing.
With the premise of self-knowledge through self-discovery, the JKD practitioner is prompted to absorb what ideas are useful and discard those that are not. The physical goal is development of speed, timing, footwork, coordination and power.
However, after Bruce Lee’s death in 1973, two variations of Jeet Kune Do have evolved: original JKD, which is promoted as the art Bruce Lee practiced; and JKD concepts, which applies Bruce Lee’s concepts to martial arts techniques drawn from various Indonesian, Philippine and Thai styles.
Jun Fan Gung Fu is an actual system, with a structure, techniques, rank structure and progression. It is true to say that this technique “is Jun Fan” and that this technique “is not Jun Fan”. Many people misunderstand Jun Fan Gung Fu or try to go around this system of techniques to go straight to Jeet Kune Do. However, Sifu Inosanto states, “You must study Jun Fan Gung Fu to understand JKD (Jeet Kune Do).
