Jeet Kune Do is a martial art that was developed by Bruce Lee in the 1960s. It is often referred to as "the way of the intercepting fist." The style was created with the intention of being a practical and efficient fighting system that utilized the most effective techniques from a variety of martial arts.

Bruce Lee was inspired to develop Jeet Kune Do after his experiences in martial arts tournaments and real-life street fights. He found that traditional martial arts were often rigid and impractical in actual combat situations. Bruce Lee believed that martial artists should be able to adapt and respond to any situation, rather than being confined to a specific set of techniques.
