In this (likely controversial) episode I argue that the differences between 'self defense' and 'sport' jiu-jitsu have largely been exaggerated. The real magic of jiu-jitsu is in training against resistance and learning to deal with pressure, not learning a set of magical 'self defense approved' techniques. If your interest is in self defense then you should still train at the best BJJ school you can find and then, if necessary, supplement the curriculum with a little bit of additional training.
