Jet Kune Do (also "Jeet Kun Do", "JKD," or "Jeet Kuen Do") is a hybrid martial arts system and life philosophy founded by martial artist Bruce Lee with direct, non classical and straightforward movements. Due to the way his style works they believe in minimal movement with maximum effect and extreme speed.
The system works on the use of different 'tools' for different situations. These situations are broken down into ranges (Kicking, Punching, Trapping and Grappling), with techniques flowing smoothly between them. It is referred to as a "style without style".
Unlike more traditional martial arts, Jeet Kune Do is not fixed or patterned, and is a philosophy with guiding thoughts. It was named for the concept of interception, or attacking your opponent while he is about to attack.
