What is Jeet Kune Do?
Over three decades before the advent of "Mixed Martial Arts," "reality-based" self defense programs, and the many hybrid "freestyle" methods that proliferate the martial art world today, Bruce Lee innovated a revolutionary martial art training process that advanced the principles of "totality" in martial art training, "realistic" and scientific training methods, and "complete freedom" for the individual practitioner. Lee named the cutting-edge training process he developed "Jeet Kune Do," which when translated means "The Way of the Intercepting Fist."
The fact of the matter is that there is no universally accepted definition of what "Jeet Kune Do" is. Some people define it as Bruce Lee's personal martial expression or Bruce Lee's martial art. Others refer to it as the art and philosophy of Bruce Lee. Some consider it merely a concept or an idea, while others view it as as a method of research and investigation.
To me, Jeet Kune Do is an art, a science, and a philosophy. Like the Yin/Yang which is the center of the JKD symbol, it's comprised of both a physical component and a mental component. With regard to the physical component, the following is my personal definition of Jeet Kune Do, based upon my over four decades of involvement with it:
"Jeet Kune Do is a non-restrictive, principle-based training process to cultivate the ability to express the human body in combative form without any limitations or restrictions."
Jeet Kune Do is more of an 'inter-disciplinary' art rather than a 'multi-disciplinary' art. It's about cultivating your body as a 'martial instrument' and then expressing your instrument with total freedom and the highest degree of efficiency and effectiveness. It is a rational, well thought-out, dynamic process of "TOTAL" martial art training that is designed to develop every facet of the individual's combative arsenal and encompasses all elements of unarmed combat training.
However, Jeet Kune Do is much more than simply a devastating martial art or a method of fighting. It is a tool for personal liberation. With regard to the mental component:
Jeet Kune Do offers a dynamic, fluid set of operating principles an individual can use to actualize their full potential as a martial artist, as well as all-encompassing philosophy to help them live life to the fullest
in all their capacities.

What is Jun Fan Gung Fu?
Jun Fan Gung Fu is the name identified with Bruce Lee's developments in the martial arts from 1959-1967. It is the name Lee assigned to the art he was teaching after he arrived in Seattle, Washington, and that he taught at the schools he opened in Seattle and Oakland. Each of these non-commercial schools was referred to as "The Jun Fan Gung Fu Institute." (Note -- While Jeet Kune Do may have existed in principle and even in training methods at an earlier date, the name "Jeet Kune Do" was not brought into direct usage by Bruce Lee until July, 1967)
Lee knew that he could not teach under the name "Wing Chun" both out of respect for Ip Man as his Sifu and also because he was not recognized as an instructor in the style. Furthermore, he had already begun making changes in what he was doing.
From the time Lee arrived in Seattle, he began to modify his classical Wing Chun method. He began to adjust the stances, angles and positions of his Wing Chun techniques, also adding longer-range kicking techniques from some of the northern gung fu styles, as well as several other striking techniques from different gung fu styles.
While Jun Fan Gung Fu is considered the precursor to Jeet Kune Do, it cannot and should not be looked at as a separate art because it isn't -- it is simply an earlier stage of Bruce Lee's personal martial art evolution. Jun Fan Gung Fu and Jeet Kune Do are interrelated and connected.
