Wing tsun kung fu is the lineage of wing chun taught from Yip Man to Leung Ting ( his last closed door student) to Keith Kernspect who spread it across Europe, at one time with 10,000 full time instructors and hundreds of thousands of students. When Kernspect came to WT, he was a professional wrestler, and the influx of so many teachers/students from various arts including pro boxing, kick boxing, wrestling, tai chi, paukua, along with bouncers, police, military security and more all influenced the developement of the system. Many modern methods of training are used by WT practitioners to develop the 'core concepts' inherent in martial and other athletic abilities. There is a large emphasis on drills that develop balance, timing, linkage, mobility, rooting and so on. Due to the emphasis on flow and mobility, one may see many similarities to internal arts tai chi and paukua ( both of which the teacher has decades of training in), as well as systema, flow aspects of wrestling, and more. Training is very supportive method between practitioners in which you learn to feed what the person needs to learn to work on. Of course we also have specific testing training to see if and how much specfic skills are being retained. This makes the training quite different than most other martial arts. Sessions are easy going and fun, but there is a specfic focus to each class. Questions, discussion, feedback etc is part of it, so there is talking between training partners. The system is quite technical even to the point of developing the fitness, balance, timing and so on. Training covers many aspects of a spectrum as each individual will develop different abilities from it. It is very much student focussed. So one goes at ones own pace and the variations in athletic ability, power, speed, timing, understanding, personal attitudes etc affect how you aquire the skills. Concept training with theory of opponent may well be bigger, stronger, faster, in better shape, etc, so how can we train to overcome that.
