Jeet Kune Do

Jeet Kune Do (截拳道; "Way of the Intercepting Fist"), often abbreviated as  JKD, is an hybrid martial art system and philosophy of life founded by the martial artist Bruce Lee. He often referred it as "the art of expressing the human body" in his writings and in interviews. Through his studies Lee came to believe that styles had become too rigid and unrealistic, that real combat was spontaneous, and that a martial artist cannot predict it, only react to it. Lee stated that his martial concept does not add more and more things on top of each other to form a system, but rather selects the best thereof. The metaphor Lee borrowed from Chan Buddhism was of constantly filling a cup with water, and then emptying it, used for describing Lee's philosophy of "casting off what is unessential". The final result was what he considered to be the bare combat essentials: Jeet Kune Do.

Background
Jeet Kune Do is unique among martial arts, as it is the first to advocate total freedom for its practitioners and the absence of "form."

Jeet Kune Do is a philosophy developed by martial arts master Bruce Lee. During his kung fu training, Lee became disenchanted with the rigid styles and forms taught by martial arts schools. While the fundamentals of each style were important building blocks, to Lee they became barriers to true mastery. He began combining elements of Wing Chun, Western Boxing, Fencing and thus Jeet Kune Do was born (since 1967).

Jeet Kune Do is not a particular style of kung fu or other martial arts, nor is it a series of techniques; it is a philosophy on living life at the pinnacle of development. Jeet Kune Do allows a martial artist to create his own expression. There aren't particular rules that make up the style -- it is a truly free art, encompassing everything, yet possessed by nothing. It rejects the rigid forms and katas used by other martial arts, and instead stresses spontaneity and intense training of the body for peak performance.

Lee also created a style of kung fu called Jun Fan (which was his birth name) to work in conjunction with Jeet Kune Do. This style can be thought of as a more practical application of the philosophies of Jeet Kune Do. It is a pragmatic and free-form approach that teaches students to be competent in all arenas of fighting.

Description
Every situation, in fighting or in everyday life, is varied. To obtain victory, therefore, it is essential not to be rigid, but to be fluid and able to adapt to any situation. Lee compared it to being like water: "Empty your mind, be formless, shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. That water can flow, or it can crash. Be water, my friend". Lee’s theory behind this was that one must be able to function in any scenario one is thrown into and should react accordingly: one should know when to speed up or slow down, when to expand and when to contract, and when to remain flowing and when to crash. It is the awareness that both life and fighting can be shapeless and ever changing that allows one to be able to adapt to those changes instantaneously and bring forth the appropriate solution.

Jeet Kune Do teaches that the best defense is a strong offense, hence the principle of an "intercepting fist". For someone to attack another hand-to-hand, the attacker must approach the target. This provides an opportunity for the attacked person to "intercept" the attacking movement. "To reach me, you must move to me. Your attack offers me an opportunity to intercept you": this means intercepting an opponent's attack with an attack of one's own instead of simply blocking it. When confronting an incoming attack, the attack is parried or deflected, and a counterattack is delivered at the same time. This is more effective than blocking and counterattacking in sequence.

Jeet Kune Do seeks to waste no time or movement, teaching that the simplest things work best. Economy of motion is the principle by which Jeet Kune Do practitioners achieve: efficiency (an attack which reaches its target in the least amount of time, with maximum force), directness (doing what comes naturally in a disciplined way), and simplicity (thinking in an uncomplicated manner, without ornamentation). This is meant to help a practitioner conserve both energy and time, two crucial components in a physical confrontation.

In Ultra Fighter
In the story, like many forms of martial arts, Jeet Kune Do is included. Billy Kang is said to be a master of Jeet Kune Do, since his physical appearance, outfit and movesets are heavily based on Bruce Lee.
