The wooden dummy form of Wing Chun, called Muk-Yan-Chong (pronounced muck-yahn-chong), is probably the most-recognized item in the martial arts today. Even though a variety of martial arts employ a wooden dummy for training, it is usually more recognized with Wing Chun.
Some Wing Chun practitioners believe that the wooden dummy's primary purpose is to condition the arms, however some also believe that it is also supposed to resemble a human body. Constant training will see many side benefits such as conditioning, timing, but the wooden dummy's primary purpose is to improve one's structure when striking a non-moving object, increasing the coordination between upper and lower bodies ("uniting" the upper and lower bodies), and creating short-range "burst" type of power.
Wooden Dummy Training
These Techniques originated in the Shaolin Monastery in Fukien Province.
The Wooden Man Techniques were seldom taught outside the Kwoon in the old days.
Why are these techniques so important?
The standard of a practitioner in his form & basics may be high but eventually they lose their standard so to prevent this constant practice on the dummy you have a permernant training partner to keep your techniques sharp
