When I look around at martial arts schools in general, I think we’re pretty radical. We took the ninja martial art that I studied in the 1970s—how people fought in Japan in the 1500s, and their specific principles—and, over some years, I took those principles and overlaid those with modern, American street protection needs. So it is a very pragmatic martial art. When people come into my school, we have a Level One which lasts from eight months to a year, depending on how often people come in. People practice 12 different fights against padded targets; they practice with themselves in a mirror, and they practice with a training partner.
