Jeet Kune Do, also Jeet Kun Do, and abbreviated JKD is an eclectic and hybrid martial art system and philosophy of life founded by the martial artist Bruce Lee
(1940–1973) in 1967 with simple and direct, or straightforward, movements and non-classical style. Jeet Kune Do practitioners believe in minimal movements with maximum effects and extreme
speed. The system works by using different "tools" for different situations, where the situations are divided into ranges, which is kicking, punching, trapping, and grappling, where
martial artists use techniques to flow smoothly between them. It is referred to as "a style without style" or "the art of fighting without fighting" as said by Lee himself. Unlike more
traditional martial arts, Jeet Kune Do is not fixed or patterned, and is a philosophy with guiding thoughts.
