Full Contact Sparring
Full Contact Sparring is a strong part of Wing Chun training. All the training in the world will not pay off unless you actually use it. If you want to learn how to fight you must actually fight. With full contact sparring virtually anything goes. This will prepare you for the random nature of a street fight. Sparring helps the student learn to penetrate with powerful hits and also to perform well under stress. Sparring is a great way to judge your distance, power and setting your range. Remember that Wing Chun was designed to enable the user to overcome a larger stronger opponent. For this reason mobility and the concept of never fighting force with force are very important concepts to maintain while sparring. Protective gear should be worn for safety while sparring at all times.
There is nothing better than free-style sparring in the practice of any combative art. In sparring you should wear suitable protective equipment and go all out. Then you can truly learn the correct timing and distance for the delivery of the kicks, punches, etc. It is a good idea to spar with all types of individuals--tall, short, fast, clumsy.
Yes, at times a clumsy fellow will mess up a better man because his awkwardness serves as a sort of broken rhythm. The best sparring partner, though, is a quick, strong man who does not know anything; a madman who goes all out, scratching, grabbing, grappling, punching, kicking, and so on.
