In 1966, karatel egend Joe Lewis rocketed to stardom by winning Jhoon Rhee's U.S. Nationals in Washington, D.C. Incredibly, it was his first tournament, and he won every single point with only one technique — the side kick. For six years, Chuck Norris ruled the karate world with his spinning kicks. He won virtually every major title between 1965 and 1970, including six grand championships. He retired, undefeated, in 1970. From 1974 to 1981, Bill "Superfoot" Wallace dominated the full-contact karate circuit. His lightning-fast left roundhouse and hook kicks rose to legendary status as he stunned one opponent after another. He retired 21-0, with 11 knockouts. Superfoot, indeed. Those champions and many more have demonstrated their awesome kicking abilities in and out of the ring. In fact, the martial arts in general are best-known for their kicks. Even Bruce Lee is remembered more for his dynamic on-screen kicking than for the intricate trapping and striking techniques of jeet kune do. If kicking is the hallmark of the martial arts, it follows logically that to become a superior fighter, you have to learn how to deal with those seemingly indefensible lower-limb assaults. How do you stop a technique that, once mastered, appears to be unstoppable? One answer can be found within William Cheung's traditional wing chun fighting system.
Mechanics of Kicking
The laws of physics hold that a force can have only one direction at a time. The longer a movement is committed to a certain direction, the longer it will take for it to change its direction. It has to run its course before it can move on to another path. When an opponent attacks with a kick as opposed to a punch, his foot must follow a longer path to reach you. Distance equals time, so the greater distance gives you more time to react. In dealing with kicks, then, the first step is to properly train your eyes, or visual reflexes, so you can readily determine how your opponent is attacking and which part of your body he is targeting. Traditional wing chun teaches you to watch your opponent's elbow to identify an upper-body strike — punch, palm strike, elbow and so on — because the movement of the elbow indicates the movement of the entire arm. The arm cannot move without the elbow going with it. The knee is to the leg as the elbow is to the arm. Thus, if you train yourself to watch the knee of your opponent's attacking leg the instant he kicks, you will have the best chance of identifying the kick's path and target. If the opponent attempts to bridge the gap with a kick, he must commit himself to that direction of force. As a defense, you can do anything. You have not committed; therefore, as long as you are balanced and have mobile footwork, you are free to move in any direction. Your response should put you in the best position not only to defend yourself but also to counterattack.
If your opponent executes a kick and it does not make contact — and it is your job to ensure that it doesn't — he will leave you several openings to exploit:
