Jeet Kune Do -截拳道-

~The Way of the Intercepting Fist~

What is Jeet Kune Do?

Jeet Kune Do is an empty-handed martial art founded by martial artist Bruce Lee.


In 1964, Bruce Lee experienced a no-rule fight which took a surprisingly long time for him to win. This experience motivated Bruce Lee to re-examine his own martial arts. In 1967, as a result of Bruce Lee’s continuous research and experimentation, he named his style of martial arts “Jeet Kune Do”.


To become more efficient, Bruce Lee had continually modified and evolved Jeet Kune Do with workout-partner Ted Wong until he passed away suddenly in 1973.


Jeet Kune Do has a unique technical system. The system’s foundation consists of not only Bruce Lee’s analysis of eastern techniques but also extends to his study of boxing and fencing history. Those particular structures, principles, tactics, etc., allowed Bruce Lee to draw from a great number of inspirations.


In other words, Bruce Lee pursued “the best method” to exercise two sets of arms and legs.


This style of martial arts is established based on scientific principles and applied physical laws.


This is also a non-classical martial art which is called the “Scientific Street Fighting”.

The History of Jeet Kune Do《Late 1964》
■The origin of Jeet Kune Do

·Bruce Lee held a no-rule fight with Fujian White Crane master Wong Jack Man at the Jun Fan Gun Fu Institute in Oakland. 


·The fight was expected to end instantly, but it took 3 minutes because Bruce Lee’s opponent fled from place to place.


·After the fight, a doubt of traditional Wing Chun’s practicability and adequacy of physical agility and cardiorespiratory-function emerged.


·Bruce Lee then began to study martial-arts/combative-sports from all ages and countries.

■Establishment of Complete Jeet Kune Do Techniques

·Bruce Lee began to use the name “Jeet Kune Do” from July 1967.


·Further considerations of the scientific principles of fighting:


 “The human body, body weight, techniques/tactics, physical laws, and philosophical principles/rules are the elements of fighting. The question is how to adopt these elements in the real live fighting most effectively and efficiently.”


·Bruce Lee then accumulated the technique experiments with Ted Wong who was both a private student and a workout/sparring partner from August 1967.
