Jeet Kune Do, or "Way Of The Intercepting Fist" was created by Bruce Lee in 1967. The art is a scientific approach to street altercations and is designed to work in real situations. It incorporates the training methods, techniques, combative principles, strategies and philosophies found to be most effective from the many different disciplines and systems that he researched and compiled during his lifetime. Originally centered around a modified form of Wing Chun, the art also blended his ideas on the strategies of Western boxing and the use of principles and tactics from Western Fencing.
The art grew to include what was most efficient, whatever its source. What was taken from various systems was simply modified to fit his needs at the time. Through experimentation and constant practice the art continuously evolved to include all ranges of fighting. Functionality in combat is the most important goal. He felt that a martial artist can't be bound by any single style or method, but should employ what is useful and efficient regardless of its origin, style or method. The ability to adapt to any kind of opponent or situation is critical. As a result he created an art that is non-classical, simple, direct, fast, powerful and deceptive.
