I created my own version of a Mook Jung (Wing Chun Dummy) back in 1992. I trained on the dummy for several hours every day for years. During that period of time I developed my own punch block patterns. These patterns were the very beginning of my creation of Shu Ha Ri Do in 1998. These patterns are absolutely only the beginning of the 7 belt system I call Shu Ha Ri Do. A system that includes conventional boxing, full contact karate principles, muay thai, wrestling, submission, creative elements, even animalistic forms.
