As a former 'JKD guy', I think it's probably best to leave these kind of discussions to JKD people, instead of looking for answers from TKD people, Karate people, Jujutsu people, Wing Chun people, Kali people, Muay Thai people, MMA people, etc. etc. I no longer consider myself a 'JKD guy', by the way. I'm now what you might call a 'MMA guy', and I'll explain why in just a moment. What's important to note is that I am in fact a former 'JKD guy', so you can trust what I'm about to tell you concerning JKD. Jeet Kune Do, or the 'Way of the Intercepting Fist' in Cantonese, was Bruce Lee's art and philosophy before he passed away. Jeet Kune Do is not to be confused with Wing Chun Gung Fu, nor is it to be confused with Jun Fan Gung Fu, as these are two entirely different systems. Nor should you confuse JKD with MMA, which is also something entirely different. Jeet Kune Do has a definate structure, just like any other martial art, and so it should not be confused with TKD or MMA, or anything else for that matter. JKD is JKD, so to find out how JKD people train, you have to ask a JKD person. The first thing most people want to know are your references. I used to train in Jeet Kune Do under a certified instructor who prefers to remain anonymous. Through him, I was able to train with several original students of Bruce Lee, either directly or indirectly. Among their names are Dan Inosanto, Taky Kimura, Daniel Lee, Ted Wong, Larry Hartsell and others. I also learned a few things from Jesse Glover, but that's a totally different system. Jesse Glover is not a 'JKD guy', and he will tell you that himself. There has been some confusion in the MAP community regarding Dan Inosanto's JKDC methods, and Ted Wong's OJKD methods, but the truth is that both men actually learned from the same person, and both of them taught the same thing. Ted Wong actually got his certificate from Dan Inosanto, so the argument is pointless. There is no such thing as JKDC and OJKD, those are just names created by people from the MMA community who did not fully understand Bruce Lee's art and philosophy. There is only one Jeet Kune Do, and anything apart from that should not be confused with JKD. I will admit, when I first heard about JKDC and what people were saying, I started to have my doubts about what Dan Inosanto was teaching. But after I finally got to know the guy, I realized that he wasn't teaching anything different from what other 'JKD guys' were teaching. There is no such thing as JKDC, just as there is no such thing as OJKD, and it often confuses me how people still think there's a difference between Dan Inosanto's methods and Ted Wong's methods. So to end this confusion, I've decided to openly share what probably should have been shared from the very beginning. Bruce Lee studied philosophy at the University of Washington in 1961, and began teaching Jun Fan Gung Fu to fellow students including Jesse Glover, James DeMille and Charlie Woo, to name a few. At that time, JKD had not been born yet. Jun Fan Gung Fu is not Jeet Kune Do, so please do not get the two of them confused. Jun Fan Gung Fu is a version of Yip Man Wing Chun which Bruce Lee modified while he was living in Seattle, Washington. I've heard a lot of the original students at that time consider Jun Fan Gung Fu to consist of 80% Wing Chun, with only about 15% of that system including methods from other purely Chinese styles. Some of the lesser styles Bruce Lee implemented into his Jun Fan Gung Fu system are Tai Chi Chuan, Tang Lang Chuan, Ying Jow Pai, Choy Lee Fut, Hung Gar and Chin-Na, so in a big way I think you could very well consider Jun Fan Gung Fu to be a Chinese American martial art system based primarily on Yip Man Wing Chun. Bruce Lee opened the very first Jun Fan Gung Fu institute in Seattle, at 4750 University Way, in 1963 to be exact. His assistant instructor at the Seattle school was Taky Kimura, but prior to this time Bruce Lee had also met Linda Emery, James Lee, Allen Joe, Wally Jay, Ed Parker and Ralph Castro, who all had a huge influence on Bruce Lee as time progressed. Bruce Lee published the book, 'Chinese Gung Fu: The Philosophical Art of Self Defense' in 1963, and it is the only book which was ever published during Bruce Lee's lifetime. If you read that book, you will have a very good idea of what Jun Fan Gung Fu consisted of in 1963, when Bruce Lee opened his first school. 'Tao of Jeet Kune Do' actually wasn't published by Bruce Lee, it was published after he died. Bruce Lee opened the second Jun Fan Gung Fu institute in 1964 in Oakland, which is where many people believe JKD was born. His assistant instructor at the Oakland school was James Lee, who Bruce awarded the 3rd rank to on March 4th, 1964. Then on August 2nd, 1964 is when Bruce Lee performed his famous demonstration at the Long Beach tournament with Dan Inosanto. That's also when Bruce Lee met Jhoon Rhee for the first time. Then in 1965, another Gung Fu master named Wong Jack Man challenged Bruce Lee to a fight at his Oakland studio. After their encounter is when Bruce Lee changed his philosophy and modified his own personal training regiment to create an entirely new system, which he called 'Jeet Kune Do'. Jeet Kune Do was taught at the Jun Fan Gung Fu institute in Oakland, but only because Bruce Lee never changed the name of his school. Jun Fan Gung Fu is not the same thing as Jeet Kune Do, and I'll explain the difference to all of you right now. Jun Fan Gung Fu consists of classical forms, whereas Jeet Kune Do does not consist of any forms whatsoever. Jun Fan Gung Fu focussed primarily on modified Chi Sao drills. Jeet Kune Do still has Chi Sao drills, but it isn't focussed on nearly as much. I've heard a lot of the original students of Bruce Lee consider Jeet Kune Do to consist of 60% Wing Chun, 15% Western Boxing, and 15% Western Fencing, with only about 10% of that system including methods from other styles. Some of the lesser styles Bruce Lee implemented into his Jeet Kune Do system are Muay Thai, Savate, Taekwondo, Jujutsu, Judo, Western Wrestling and Chin-Na. Now when I say Bruce Lee implemented different styles into his own personal unique system, I don't mean that he taught all those different systems at his school. It was not a MMA program. Bruce Lee only taught one system, JKD, which simply borrowed elements, principles or techniques from different styles and combined them into one formless art. By formless, I mean it did not have katas or kuens. JKD's main focus was on full-contact sparring, cardio exercizes and two-man drills. I don't know where people get the idea that Jeet Kune Do was made up of 26 different martial arts. That simply is not true. JKD was the next step in evolution from Jun Fan Gung Fu, which is why today many of Bruce Lee's students call it Jun Fan Jeet Kune Do, to distinguish it from MMA and other false JKD schools that try to use Bruce Lee's fame and philosophy to teach TKD, Karate, Gung Fu, Ninjutsu, Kali, Muay Thai, Aikido, or something else which isn't necessarily related to JKD in any way whatsoever. As I said before, JKD is not MMA, and it should never be confused as such when learning it directly. Bruce Lee opened the third and final Jun Fan Gung Fu institute in Los Angelos, California at 628 College Street, in 1966 to be exact. Notice he kept the name of his school, but by this time he was teaching Jeet Kune Do, which was totally different from what he had taught Jesse Glover and his Jun Fan Gung Fu students in Seattle, with the exception of Taky Kimura, who Bruce Lee kept updated on the new JKD regiment. Many newcomers to the L.A. studio were former students of Ed Parker, so it's no wonder why a lot of Karate guys try to implement JKD elements into their training. Ed Parker's system is not Bruce Lee's system, however, nor should anyone ever confuse JKD with Karate, Judo, Taekwondo or anything else for that matter. Bruce Lee's assistant instructor at the L.A. school was Dan Inosanto, who had actually started training with Bruce Lee prior to the opening of the L.A. school. Bruce Lee had been training with Dan Inosanto, Tony Hum and Wayne Chan at a pharmacy in Los Angelos, but the first person to actually join the Jun Fan Gung Fu institute in L.A. was none other than Daniel Lee. Bruce Lee awarded Dan Inosanto with the 3rd JKD rank in February of 1967. Bruce Lee awarded Taky Kimura with the 5th JKD rank on November 1st, 1967. Bruce Lee awarded Ted Wong with the 2nd JKD rank on December 8th, 1967. That year, Bruce Lee met Chuck Norris, Mike Stone and Joe Lewis in Washington, D.C. at a Karate tournament. Not one of these three guys lost a single fight during their JKD training with Bruce Lee. Then in 1968, Bruce Lee closed down all three of his schools and suddenly abandoned the ranking system for unknown reasons. He permitted a few of his students to teach JKD, but only in small groups under very tight conditions. A few years after that, Bruce Lee fell into a mysterious coma and died before his last film, 'Game of Death', could be completed. He was buried at Lake View cemetary in Seattle, Washington. His pallbearers were Robert Lee, Taky Kimura and Dan Inosanto. The rest as they say, is history. Shortly after that, Dan Inosanto opened his own Kali Academy where he continued to teach JKD in small groups. Dan Inosanto also gave JKD certificates to a few of the guys who were at the L.A. studio before it closed. Among them were guys like Ted Wong who he felt Bruce Lee would have trusted to preserve his martial arts legacy. The only problem with this is that Dan Inosanto didn't just teach JKD at the Kali Academy, he taught several different systems and scheduled several classes for each system he taught. So you had a lot of MMA guys who learned all these different styles from Dan Inosanto, and a lot of these MMA guys started to think that MMA was JKD, or that JKD was just a philosophy used in MMA training. That's where a lot of these different opinions and misconceptions came from. But it's important to note that Dan Inosanto taught JKD classes seperate from other classes. Never once did he teach Kali and call it JKD, nor did he ever teach Kenpo and call it JKD, because he was teaching different classes at the time. Jun Fan Jeet Kune Do is not MMA, nor is it a concept which can be applied or confused with other martial art systems. You can use the JKD philosophy to help you train in other martial art systems, but at no time should you ever get JKD confused with the style you are learning. A good example would be if I took Wing Chun's philosophy and applied it to Karate. Yes, that is MMA training, and yes, it would probably be beneficial to my training in Karate, but to then consider Karate to be the same style as Wing Chun would be absurd, and that is what people are trying to do nowadays with JKD, they are labelling it as something that it is not. I no longer consider myself a 'JKD guy' because I know the difference, and because I respect Bruce Lee's art and philosophy for what it truly is. Even though I train in Wing Chun, Western Boxing, Western Fencing, Muay Thai, Savate and all these other styles, that does not mean I practice JKD, because JKD and MMA are two totally different things. JKD has a definate structure. It has footwork, sparring drills, fighting stances and techniques which are completely unique to JKD, therefore it is important not to confuse that structure with any other structure you might have learned. I say again, MMA is not JKD. I truly hope this helps.
