Kaufman Wing Chun Center of Mass

This is a video by Hong Kong Sifu John Kaufman, who teaches the Chu Shong Tin method of Wing Chun kung fu. The video (with John's USA student, Brent Parkinson) discusses and demonstrates using the center of mass to generate power for both defense and offense. (BTW in the video, several times I say "center of gravity" but I really mean, "center of mass).Sifu Kaufman may be contacted at john.kaufman21@gmail.com and is available for private/group lessons and seminars worldwide.
