JEET KUNE DO - The Principles

The following are principles that Lee incorporated into Jeet Kune Do. He felt these were universal combat truths that were self evident and would lead to combat success if followed. The "Three Combat Ranges" in particular are what he felt were instrumental in becoming a "total" martial artist. This is also the principle most related to mixed martial arts. Bruce Lee's notes explain THREE RANGES OF COMBAT and can be found both in the Tao of Jeet Kune Do and Jeet Kune Do as edited by John Little. Bruce Lee students such as Ted Wong, Jerry Poteet and others teach THREE ranges of combat. Dan Inosanto has modified these into FOUR ranges of combat, and thus, it is a Jeet Kune Do Concepts addition.

JKD practitioners also subscribe to the notion that the best defense is a strong offense, hence the principle of "Intercepting". Lee believed that in order for an opponent to attack someone they had to move towards them. This provided an opportunity to "intercept" that attack or movement. The principal of interception covers more than just intercepting physical attacks. Lee believed that many non-verbals and telegraphs (subtle movements that an opponent is unaware of) could be perceived or "intercepted" and thus be used to one's advantage. The "5 Ways of Attack" are attacking categories that help Jeet Kune Do practitioners organize their fighting repertoire and comprise the offensive portion of JKD. The concepts of Stop hits & stop kicks and simultaneous parrying & punching were borrowed from western Fencing and comprise the defensive portion of JKD. These concepts were modified for unarmed combat and implemented into the JKD framework by Lee. These concepts also compliment the other principal of interception.



I. Be like water

Lee believed that martial systems should be as flexible as possible. He often used water as an analogy for describing why flexibility is a desired trait in martial arts. Water is infinitely flexible. It can be seen through, and yet at other times it can obscure things from sight. It can split and go around things, rejoining on the other side, or it can crash through things. It can erode the hardest rocks by gently lapping away at them or it can flow past the tiniest pebble. Lee believed that a martial system should have these attributes. JKD students reject traditional systems of training, fighting styles and the Confucian pedagogy used in traditional kung fu schools because of this lack of flexibility. JKD is claimed to be a dynamic concept that is forever changing, thus being extremely flexible. "Absorb what is useful; Disregard that which is useless" is an often quoted Bruce Lee maxim. JKD students are encouraged to study every form of combat possible. This is believed to expand one's knowledge of other fighting systems; to both add to one's arsenal as well as to know how to defend against such tactics.


II. Economy of motion

JKD students are told to waste no time or movement. When it comes to combat JKD practitioners believe the simplest things work best.

A. Stop hits & stop kicks

This means intercepting an opponent's attack with an attack of your own instead of a simple block. JKD practitioners believe that this is the most difficult defensive skill to develop. This strategy can be a feature of some traditional Chinese martial arts.

B. Simultaneous parrying & punching

When confronting an incoming attack; the attack is parried or deflected and a counter attack is delivered at the same time. Not as advanced as a stop hit but more effective than blocking and counter attacking in sequence. This is also practiced by some Chinese martial arts.

C. No high kicks

JKD practitioners believe they should target their kicks to their opponent's shins, knees, thighs, and mid section. These targets are the closest to the foot, provide more stability and are more difficult to defend against. However, as with all other JKD principles nothing is "written in stone". If a target of opportunity presents itself; even a target above the waist one could take advantage of the situation without feeling hampered by this principle.
