When you need your martial arts to work in practical self protection situations... Or when you train certain moves but are presented with inadequate reasons for using those techniques (or worse, no answers at all)... Then you need the books and DVDs, seminars and courses of John Burke. With practical kata bunkai as his speciality, John Burke trains groups from all sorts of styles and affiliations in how to use the moves that they are taught practically. That means with close-range attacks in realistic situations, not oizuki/mawashigeri/ushirogeri from 8meters away. The moves of kata are shown to contain throws, locks, holds, pain compliance and destruction techniques. There are buyers and students of this material all over the world, from England to Japan. Buy now, and enjoy the Bunkai.
