On April 11, Chris Bobek and I were in San Francisco to conduct a WingChun Self-Defense Workshop at the Excelsior Clinic of the Chinese Hospital system as part of their Community Wellness Program. We customized the presentation to the audience by focusing on the naturalness and aliveness of WingChun movements. Interactive exercises were used to demonstrate how our training creates strong and proper alignment in the body. Then, these powerful physical principles were examined in Self-Defense application. The participants were able to understand and perform the instructions very well. Thanks to Chelsea Mao, Program Development Manager, for inviting us and planning out the event.
