What is Jeet Kune Do? podcast

Part 1: Style v. Concepts

There are a many arguments about the term Jeet Kune Do (JKD). Some take the position that it is the exact techniques that Bruce Lee practiced before his death. Others say that it is any combination of martial arts that a student uses. People are passionate about the topic but I think some of the controversy is because Bruce Lee used different language about JKD at different times of his life. Here are my thoughts about the subject based on his writings.

Early on he called JKD a “style” and highlighted its connection to Wing Chun. In a February 1965 letter he wrote that he wanted to start his own system of martial arts that is based on simplicity. He said the “root” of martial arts is rhythm, timing, and distance. Wing Chun was the “starting point” but he added the Five Ways of Attack. He concentrated on “irregular rhythm” and to intercept an opponent in the most efficient way (Letters, page. 44). In another letter of the same year he said that rhythm and distance is the foundation of martial arts but simplicity is also a necessary component (Letters, page 43). His style was based on timing and distance and Wing Chun was the “nucleus” (Letters, page 57).

As he continued to develop JKD he incorporated other styles such as boxing and fencing. He stressed the importance of economy of motion and said that JKD was more efficient than Wing Chun (Letters, pages 98, 111). He incorporated boxing but said it had too big a range of motion around the “center line” (Letters p. 75). Although boxing was important to JKD, practicality was even more important (Letters, page 124).

Later in his life he got away from the idea JKD being a style. He said he did not invent a new martial art and wanted people to improve JKD. He was not creating another branch of martial arts because that is when learning stops (Commentaries, Page 327). He did not believe in system or method (Commentaries, Page 329). JKD “uses all ways and is bound by none” and uses any technique to “serve its ends” (Commentaries, Page 55). He even decided to close his martial art schools because he did not want the students to take his curriculum as truth (Commentaries, Page 59).

JKD centered around individualization and self-expression. He didn’t want students to do a technique, but to express themselves through their technique and be like an echo with no “deliberation” (Commentaries, page 87) and is self-expression (Commentaries, page 349). He is after the “root” and not the “branches” where real knowledge equals personal expression while surface knowledge equals “mechanical conditioning” (Commentaries, page 385). He said learning under the Jun Fan System starts with “sticking to the nucleus,” then “liberation from the nucleus,” and finally “returning to the original freedom” (Commentaries, page 299).

In June of 1972, Bruce Lee gave an interview to a Taiwan newspaper called Me and Jeet Kune Do. He says, “I want to emphasize that there is no clear line of distinction between ‘Jeet Kune Do’ and any other kind of Gung Fu. What is Jeet Kune Do? Chinese martial art, definitely! It is a kind of Chinese martial art that does away with distinction of branches, an art that rejects formality, and an art that is liberated from tradition…It is ridiculous to pin down so-and-so’s type of Gang Fu as ‘Bruce Lee’s Jeet Kune Do.’ I call it Jeet Kune Do just because I want to emphasize the notion of deciding at the right moment in order to stop the enemy at the gate. Really there is no rigid form in Jeet Kune Do. All that there is is this understanding: If the enemy is cool, stay cooler than him. If the enemy moves, move faster than him; be concerned with the ends, not the means; master your own manipulation of force, don’t be restricted by your form.” (Words, 126-128).

So where does that leave JKD? I think he first saw JKD as a new style and an extension of Wing Chun. Then it developed beyond Wing Chun incorporating techniques from many other styles including boxing, Wing Chun, Tae Kwon Do, Hapkido, and fencing. He was trying to get to the totality of martial arts and not just any one part or style. The particular style wasn’t important because he wanted the student to focus on practicality, efficiency, and timing. JKD became so centered around individualized self-expression that he shut down his schools to avoid teaching a specific curriculum.

With all that being said, I still think students should learn, explore, and practice the specific martial arts techniques used by Bruce Lee. In my opinion these techniques are practical, effective, efficient, and based on science. Students should then “Absorb what is useful, discard what is not, add what is uniquely your own” (Bruce Lee).

Part 2: Techniques v. Principles

As I’m thinking about what Jeet Kune Do (JKD) actually is, I wanted to identify techniques and principles. In my mind the principles are universal and define what JDK truly is. If you don’t do the principles then you are not doing JKD. Techniques are specific martial arts methods used by Bruce Lee. These should be investigated and the student should, “Absorb what is useful, discard what is not, add what is uniquely your own” (Bruce Lee). Of course this list is not complete and only my thoughts at this moment. This could change over time.

Part 3: The Intangibles (Fluidity, Totality, Simplicity, Rhythm, Timing, and Distance)

Jeet Kune Do (JKD) in Cantonese, means “The Way of the Intercepting Fist.” This is the name Bruce Lee gave to his philosophy and personal approach to martial arts. It emphasizes using timing and rhythm to intercept an opponent’s attack. Click the words below on the JKD image to explore further.

Five Ways of Attack

Simple Direct Attack (SDA), Attack By Combination (ABC), Progressive Indirect Attack (PIA), Hand Immobilizing Attack (HIA), Attack By Drawing (ABD)

Timing, Rhythm, and Distance

Timing was very important to Lee. He wanted to be able to anticipate when an opponent might strike and notice patterns to the opponent’s attacks. Broken rhythm involves starting with a pattern of attack against an opponent and then changing the pattern to confuse the opponent. For example, you might do a jab and punch combination several times. On the fourth time you throw a jab and then an uppercut to see if you can make contact with the opponent. Distance: It can be helpful to think about a fight using ranges. The long range involves kicking attacks, medium range includes kicking and punching attacks, and short/close range includes short kicking, punching, trapping, and grappling. It helps to notice which range you excel at and which range your need to practice.

Fluidity

Lee is well known for his quote to “Be like water.” Water is fluid and moves around obstacles. In the same way his fighting philosophy emphasizes adapting to the opponent. Don’t box a boxer or wrestle a grappler. Consider the size of yourself and your opponent and make sure to choose the best type of attack that works in your particular situation.

Simplicity: (Economy of Motion) All attacks and defenses should be done as simple as possible. They should be the most efficient and direct as possible. Totality: Bruce Lee did not believe in being constrained to one traditional martial arts style. All the styles are parts of a total defense system using all parts of the body including fists, feet, knees, and elbows.
