I've put together the attached presentation for people attending an introductory course for a few reasons: It's important information for self defence. It takes a long time to cover the information in class. It is easier to edit and be thorough and consistent when presenting the content. It frees up class time for more physical things. People can watch it at their leisure and re-watch if they want. Someone else can use it if they want. This is really the framework/context in which the fundamentals class runs. Link .
