Remember that Jeet Kune Do is merely a name used, a mirror in which to see "ourselves". Either you understand or you don't, and that is that. Every movement in Jeet Kune Do is being so of itself. I always believe that the easy way is the right way.
Jeet Kune Do is simply the direct expression of one's feelings with the minimum of movements and energy.
These situations are broken down into ranges (Kicking, Punching, Trapping and Grappling), with techniques flowing smoothly between them. 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.
Originally, when Lee began researching various fighting styles, he gave his martial art his own name of Jun Fan Gung Fu.
However not wanting to create another style that would share the limitations that all styles have, he instead gave us the process that created it.
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 (振藩截拳道) to refer to the martial arts system that Lee founded.
The core concepts of JKD are derived from Wing Chun.
This includes such ideas as centerline control, punching with a vertical fist, trapping, and forward pressure.
