bruce lee was an exceptional forms person. he did practice the first form from wing chun, sil lum tao, and part of the second form, chum kiu, as he didnt learn it in it's entirety, and as much of the mook jong, or wooden man form as he learned. bruce didnt complete his wing chun training and missed out on the weapons sets, as far as i have seen in all the reading i have done over the years. he did learn forms from other systems as well. yes, he did teach the ung moon and some jkd instructors still teach it today. ron balicki is one such instructor and the form can be found on his 8 dvd series, jun fan jkd, beginner to apprentice level.
there came a time when people were saying forms were bad because they didnt truly listen to lee. he didnt say that they were useless as much as he stated that no one fights like that in real life. however, forms arent about teaching fighting as much as they are about teaching structure. to say that forms are all bad is to misunderstand the true nature of forms. there are disagreements on this point but i think a person should investigate this for themselves and arrive at their own conclusions.
in the beginning, forms are good to help students learn about physical structure, balance, movement and such things. do not see forms as a way to fighting. and do not make forms your end all be all, just as you shouldnt make sparring your end all be all. some people have taken sparring and placed way too much emphasis on it. it is yet another tool for personal development. but because lee placed heavy emphasis on it, others simply followed suit, which was the opposite thing lee was "preaching" in his philosophical approach to jkd. all the elements of training have importance.
i use a training drill for developing kicking and for exercise that is based upon an 8 point position. using numbers, i go clockwise in a circle around me. picture a + and an x shape superimposed on each other. kick front kick straight ahead. along the next line, which is a diagonal, perform a side kick. along the next line on the + , which would be "3", a back kick. repeat the pattern in a circle and you switch to the other leg afterwards. it is a moving kicking exercise that develops foot placement, kicking skills, looking skills, as you must look before you kick, and isnt too bad for an aeorbic exercise either. it isnt a fighting form. there isnt a form for fighting. which brings us back to the question about forms. no form works for fighting. it should only be for drilling. by the way, ive created variations for this kicking form to drill different kicks and combination kicks. ive been using this method for many years. recently i saw it being performed by a jkd instructor on one of the jun fan jkd annual seminar videos with all the original jkd 1st gens...
