It's fantastic. Haven't done it myself but know some people who have, it is not only a super workout but possibly the most practical self-defense training I have ever heard of in the sense that you do not have to study for ages to become proficient at kicking ass. (Defensively, of course).

The friend who did it was already in elite-class athlete shape and praised the intensity of the workout, + he was the person least in need of self-defense training that I know and praised the skills that he learned in that area. I am considering doing it myself, the strikes sound earily familiar to the Japanese karate that I studied for a while. (Mas Oyama).
