Bruce Lee designed his own martial arts even before he became a movie star. The system of specific martial arts techniques known as Jeet Kune Do, was taught at his generally closed to the public schools. There are a handful of teachers who still instruct in the original system as Lee taught, but they are not easy to find. Youtube is littered with Jeet Kune Do videos that have nothing resembling the art of Bruce Lee.
The official website of Jeet Kune Do www.WorldJkd.com and www.Jeetkunedo.org is the first place you should look to find the real deal when it comes to training.
Like anything, do your research, and if its easily available, it is most likely not the original JKD. There is even a youtube video with over one million views on “What is Jeet Kune Do” that is completely false information.
There are very very few real JKD instructors of this elite martial art.
