About JKDC

Jeet Kune Do Concepts, also Jeet Kun Do Concepts, and abbreviated JKDC, is a hybrid martial art system and philosophy of life founded by the martial artist Bruce Lee (1940–1973) in 1960 with simple and direct, or straightforward, movements and non-classical style. Jeet Kune Do practitioners believe in minimal movements with maximum effects and extreme speed. The system works by using different "tools" for different situations, where the situations are divided into ranges, which is kicking, punching, trapping, and grappling, where martial artists use techniques to flow smoothly between them. It is referred to as "a style without style" or "the art of fighting without fighting" as said by Lee himself. 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 while one's opponent is about to attack. However, the name Jeet Kune Do was often said by Lee to be just a name. He himself 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. He called martial art competitions of the day "dry land swimming". 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; "Jun Fan" was Lee's Chinese given name.

Lee's philosophy

Jeet Kune Do (JKD) is the name Lee gave to his combat system and philosophy. Originally, when Lee began researching various fighting styles, he called it Jun Fan Gung Fu. However not wanting to create another style that would share the limitations that all styles had, he instead described the process that he used to create it:JKD as it survives since then—if one views it "refined" as a product, not a process—is what was left at the time of Lee's death. It is the result of the lifelong martial arts development process Lee went through. Lee stated that his 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 useless". He used the sculptor's mentality of beginning with a lump of clay and removing the material that constituted the "unessentials"; the end result was what he considered to be the bare combat essentials, or JKD.

The dominant or strongest hand should be in the lead because it would perform a greater percentage of the work. Lee minimised the use of other stances except when circumstances warranted such actions. Although the On-Guard position is a formidable overall stance, it is by no means the only one. He acknowledged that there were times when other positions should be utilised.

Lee felt the dynamic property of JKD was what enabled its practitioners to adapt to the constant changes and fluctuations of live combat. He believed that these decisions should be made within the context of "real combat" and/or "all out sparring" and that it was only in this environment that a practicianer could actually deem a technique worthy of adoption.

Lee did not stress the memorisation of solo training forms, or "Kata", as most traditional styles do in their beginning-level training. He often compared doing forms without an opponent to attempting to learn to swim on dry land. Lee believed that real combat was alive and dynamic. Circumstances in a fight change from millisecond to millisecond. Thus, pre-arranged patterns and techniques are not adequate in dealing with such a changing situation. As an antidote to this line of thought, Lee once wrote an epitaph which read: 'In memory of a once fluid man, crammed and distorted by the classical mess.' The "classical mess" in this instance was what Lee thought of classical martial arts.

Principles

The following are principles that Lee incorporated into Jeet Kune Do. Lee felt these were universal combat truths that were self-evident, and would lead to combat success if followed. Familiarity with each of the "Four ranges of combat", in particular, is thought to be instrumental in becoming a "total" martial artist.

JKD teaches that the best defence is a strong offence, 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. The principle of interception may be applied to more than intercepting physical attacks; non-verbal cues (subtle movements that an opponent may be unaware of) may also be perceived or "intercepted", and thus be used to one's advantage.

The "Five ways of attack", categories which help JKD practitioners organise their fighting repertoire, comprise the offensive teachings of JKD. The concepts of "Stop hits & stop kicks", and "Simultaneous parrying & punching", based on the concept of single fluid motions which attack while defending (in systems such as épée fencing and Wing Chun), compose the defensive teachings of JKD. These concepts were modified for unarmed combat and implemented into the JKD framework by Lee to complement the principle of interception.

Straight lead

Lee felt that the straight lead was the most integral part of Jeet Kune Do punching, as he stated, "The leading straight punch is the backbone of all punching in Jeet Kune Do. "The straight lead is not a power strike but a strike formulated for speed. The straight lead should always be held loosely with a slight motion, as this adds to its speed and makes it more difficult to see and block. The strike is not only the fastest punch in JKD, but also the most accurate. The speed is attributed to the fact that the fist is held out slightly making it closer to the target and its accuracy is gained from the punch being thrown straight forward from one's centerline. The straight lead should be held and thrown loosely and easily, tightening only upon impact, adding to one's punch. The straight lead punch can be thrown from multiple angles and levels.

Non-telegraphed punch

Lee felt explosive attacks with no telegraphing signs of intention were best. He argued that the attacks should catch the opponent off-guard, throwing them off their balance and leaving them unable to defend against further attacks. "The concept behind this is that when you initiate your punch without any forewarning, such as tensing your shoulders or moving your foot or body, the opponent will not have enough time to react," Lee wrote. The key is that one must keep one's body and arms loose, weaving one's arms slightly and only becoming tense upon impact. Lee wanted no wind-up movements or "get ready poses" to prelude any JKD attacks. Lee explained that any twitches or slight movements before striking should be avoided as they will give the opponent signs or hints as to what is being planned and then they will be able to strike first while one is preparing an attack. Consequently, non-telegraphed movement is an essential part of Jeet Kune Do philosophy.

"Be like water"

Lee emphasized that 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. He 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. Lee did not believe in "styles" and felt that every person and every situation is different and not everyone fits into a mould; one must remain flexible in order to obtain new knowledge and victory in both life and combat. One must never become stagnant in the mind or method, always evolving and moving towards improving oneself.

Economy of motion

Jeet Kune Do seeks to waste no time or movement, teaching that the simplest things work best, as in Wing Chun. Economy of motion is the principle by which JKD 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.
• 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. Maximized force seeks to end the battle quickly due to the amount of damage inflicted upon the opponent. Rapidity aims to reach the target before the opponent can react, which is half-beat faster timing, as taught in Wing Chun and Western boxing. Learned techniques are utilised in JKD to apply these principles to a variety of situations.

Stop hits and stop kicks

"When the distance is wide, the attacking opponent requires some sort of preparation. Therefore, attack him on his preparation of attack." "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. It is for this concept Jeet Kune Do is named. JKD practitioners believe that this is the most difficult defensive skill to develop. This strategy is a feature of some traditional Chinese martial arts as Wing Chun, as well as an essential component of European épée fencing. Stop hits and kicks utilise the principle of economy of motion by combining attack and defence into one movement, thus minimising the "time" element.

Simultaneous parrying and punching

When confronting an incoming attack, the attack is parried or deflected, and a counterattack is delivered at the same time. This is not as advanced as a stop hit but more effective than blocking and counterattacking in sequence. This is practised by some Chinese martial arts such as Wing Chun, and it is also known in Krav Maga as "bursting". Simultaneous parrying & punching utilises the principle of economy of motion by combining attack and defence into one movement, thus minimising the "time" element and maximising the "energy" element. Efficiency is gained by utilising a parry rather than a block. By definition a "block" stops an attack, whereas a parry merely re-directs it. Redirection has two advantages, first that it requires less energy to execute and second that it utilises the opponent's energy against them by creating an imbalance. Efficiency is gained in that the opponent has less time to react to an incoming attack, since they are still nullifying the original attack.

Low kicks

JKD practitioners believe they should direct their kicks to their opponent's shins, knees, thighs, and midsection, as in Wing Chun. These targets are the closest to the foot, provide more stability and are more difficult to defend against. Maintaining low kicks utilises the principle of economy of motion by reducing the distance a kick must travel, thus minimising the "time" element. However, as with all other JKD principles nothing is "written in stone". If a target of opportunity presents itself, even a target above the waist, one could take advantage of the situation without feeling hampered by this principle.

Four ranges of combat

• Kicking
• Punching
• Trapping
• Grappling

Jeet Kune Do students train in each of the aforementioned ranges equally. According to Lee, this range of training serves to differentiate JKD from other martial arts. Lee stated that most but not all traditional martial arts systems specialise in training at one or two ranges. Lee's theories have been especially influential and substantiated in the field of mixed martial arts, as the MMA Phases of Combat are essentially the same concept as the JKD combat ranges. As a historic note, the ranges in JKD have evolved over time. Initially the ranges were categorised as short or close, medium, and long range. These terms proved ambiguous and eventually evolved into their more descriptive forms, although some may still prefer the original three categories.

Five ways of attack

The original five ways of attack are:

1. Single direct attack (SDA)
2. Attack by combination (ABC)
3. Progressive indirect attack (PIA)
4. (Hand) immobilization attack (HIA)
5. Attack by drawing (ABD)
• Simple angle attack (S.A.A.)
• Immobilization attack (I.A.)
• Progressive indirect attack (P.I.A.)
• Attack by combination (A.B.C.)
• Attack by drawing (A.B.D.)

Centerline

The centerline is an imaginary line drawn vertically along the center of a standing human body, and refers to the space directly in front of that body. If one draws an isosceles triangle on the floor, for which one's body forms the base, and one's arms form the equal legs of the triangle, then h (the height of the triangle) is the centerline. The Wing Chun concept is to exploit, control and dominate an opponent's centerline. All attacks, defences, and footwork are designed to guard one's own centerline while entering the opponent's centerline space. Lee incorporated this theory into JKD from his sifu Yip Man's Wing Chun.

The three guidelines for centerline are:

• The one who controls the centerline will control the fight.
• Protect and maintain your own centerline while you control and exploit your opponent's.
• Control the centerline by occupying it.

This notion is closely related to maintaining control of the center squares in the strategic game chess. The concept is naturally present in xiangqi (Chinese chess), where an "X" is drawn on the game board, in front of both players' general and advisors.

Combat realism

One of the premises that Lee incorporated in Jeet Kune Do was "combat realism". He insisted that martial arts techniques should be incorporated based upon their effectiveness in real combat situations. This would differentiate JKD from other systems where there was an emphasis on "flowery technique", as Lee would put it. Lee claimed that flashy "flowery techniques" would arguably "look good" but were often not practical or would prove ineffective in street survival and self-defense situations. This premise would differentiate JKD from other "sport"-oriented martial arts systems that were geared towards "tournament" or "point systems". Lee felt that these systems were "artificial" and fooled their practitioners into a false sense of true martial skill. Lee felt that because these systems favoured a "sports" approach they incorporated too many rule sets that would ultimately handicap a practitioner in self-defense situations. He felt that this approach to martial arts became a "game of tag" which would lead to bad habits such as pulling punches and other attacks; this would again lead to disastrous consequences in real world situations.

Another aspect of realistic martial arts training fundamental to JKD is what Lee referred to as "aliveness". This is the concept of training techniques with an unwilling assistant who offers resistance. Lee made a reference to this concept in his famous quote "Boards don't hit back!" Because of this perspective of realism and aliveness, Lee utilised safety gear from various other contact sports to allow him to spar with opponents "full out". This approach to training allowed practitioners to come as close as possible to real combat situations with a high degree of safety.

Branches

Although Lee officially closed his martial arts schools two years before his death, he allowed his curriculum to be taught privately. Since his death, Jeet Kune Do is argued to have split into different groups. Allegedly they are:

• The Original (or Jun Fan) JKD branch, whose proponents include Taky Kimura, James Yimm Lee, Jerry Poteet, and Ted Wong; these groups teach what was developed and taught by Lee, and encourage the student to further develop his or her self and abilities through those teachings. The inherent training principles of this branch are shaped by the concepts of what was "originally taught", by Lee, which does include concepts that are often misused and misunderstood. Some argue these theories are merely viewed in different contexts by the two branches.
• The JKD Concepts branch, whose proponents include Dan Inosanto, Richard Bustillo, and Larry Hartsell; these groups strive to continue the philosophy of individual self-expression through re-interpretation of combat systems through the lens of Jeet Kune Do, under the concept that it was never meant to be a static art but rather an ongoing evolution, and have incorporated elements from many other martial arts into the main fold of its teachings (most notably, grappling and Kali/Escrima material) based on the individual's personal preferences and physical attributes. The entire "system" can be described through a simple diagram, and the concepts can then be applied to a variety of contexts in a "universal" way.

As far as is known, Lee himself authorised only one person to teach Jeet Kune Do: Daniel Inosanto, who achieved 3rd rank in JKD. Ted Wong, Lee's last student, achieved 2nd rank in Jeet Kune Do while training privately with Lee. After this, Lee did away with rankings in his teachings, so Ted was never "ranked" beyond the 2nd. Dan Inosanto, however, fully certified Ted Wong to teach after Lee's death.

Two other people were certified to teach by Lee as well. Taky Kimura and James Yimm Lee were certified to teach Jun Fan Gung Fu (the precursor to JKD), but not Jeet Kune Do itself.

There are essentially two "types" or viewpoints of Jeet Kune Do:

1. JKD framework This type of JKD provides the guiding principles. Lee experimented with many styles and techniques to reach these conclusions. To Lee these principles were truisms. The JKD framework is not bound or confined by any styles or systems. This type of JKD is a process.
2. JKD Personal Systems This type of JKD utilises the JKD framework along with any techniques from any other style or system to construct a "personal system". This approach utilises a "building blocks" manner in which to construct a personalised system that is especially tailored to an individual. Lee believed that only an individual could determine for oneself what the usefulness of any technique should be. This type of JKD is thus a product, but left to personal interpretation and therefore drifts further from what Lee actually developed and employed.

Lee believed that this freedom of adoption was a distinguishing property from traditional martial arts.

There are many who confuse the JKD Framework with a JKD Personal System (i.e. Lee's personal JKD) thinking them to be one and the same. The system that Lee personally expressed was his own personal JKD; that is, tailored for himself. Before he could do this, however, he needed to first develop the "JKD Framework" process. Many of the systems that Lee studied were not to develop his "Personal JKD" but rather to gather the "principles" for incorporation in the JKD Framework approach. The uniqueness of JKD to Lee is that it was a "process", not a "product", and thus not a "style" but a system, concept, or approach. Traditional martial arts styles are essentially a product that is given to a student with little provision for change. These traditional styles are usually fixed and not tailored for individuals. Lee said there were inherent problems with this approach and established a "process" based system rather than a fixed style which a student could then utilise to make a "tailored" or "personal" product of their own. To use an analogy: traditional martial arts give students fish to eat (a product), but Lee believed that a martial art should just teach the student to fish (a process) and gain the food directly.

The two branches of JKD differ in what should be incorporated or offered within the "JKD Framework". The Original (or Jun Fan) JKD branch believes that the original principles before Lee died are all that is needed for the construction of personalised systems. The JKD Concepts branch believe that there are further principles that can be added to construct personalised systems. The value of each Branch can be determined by individual practitioners based on whatever merits they deem important.

Original JKD is further divided into two points of view, which both hold Wing Chun, Western boxing, and Fencing as the cornerstones of Lee's JKD.

• OJKD follows all Lee's training from early Jun Fan Gung Fu (Seattle period) and focuses on trapping with Wing Chun influence. This is his teachings before they were Jeet Kune Do, but still his kung fu interpretations.
• Jun Fan Jeet Kune Do is a signature version of JKD as Lee taught privately to Ted Wong. This is a later time period and practices a greater emphasis on elusiveness and simplified trapping unique to Lee's later approach to combat. The focus is with Wing Chun, Western boxing, and Fencing.
