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. However the name Jeet Kune Do was often said by Bruce Lee to be just a name. He himself often referred to it as "The art of expressing the human body" in his writings and in interviews. Through his studies Bruce came to believe that styles had become too rigid, and unrealistic.
He believed that combat was spontaneous, and that a martial artist cannot predict it, only react to it, and that a good martial artist should "Be like water" and move fluidly without hesitation.
In 2004, the Bruce Lee Foundation decided to use the name Jun Fan Jeet Kune Do to refer to the martial arts system that Lee founded. "Jun Fan" was Lee's Chinese given name.
