Founded by legendary martial artist Bruce Lee in 1967, Jeet Kune Do (JKD) is a hybrid martial art that focuses on using tools that cause maximum amount of damage with minimum amount of effort.

Sijo Lee (Sijo = founder) believed real combat was spontaneous, and a martial artist cannot predict it, but only react to it, and a good martial artist should “be like water”—moving fluidly without hesitation. JKD is a philosophy and concept developed for street combat where rules and weight divisions are nonexistent. A JKD practitioner would seek to attack the direct line to the target and continue to attack using limitless amount of techniques and the most effective tools until the fight has been terminated.
