Jeet Kune Do is the art that was developed and taught by Bruce Lee. It is a form of kickboxing that utilizes fast, efficient and non-telegraphic attacks, movements and footwork. The JKD practitioner relies on deceptive movements, speed, timing and rhythm to overcome his attacker. Interception is key - that ability to strike an attacker before their attack can land on you. Another element of JKD is trapping, which uses structure and tactile response to remove blocks/obstructions and tie up the attacker, leaving open lines for your own attacks.
Jeet Kune Do at Black Dragon Self Defense Academy is taught how Bruce Lee taught it to his students. We do not add things or take them away - if Bruce Lee taught it, so do we.
