With so many DVDs and books being churned out these days on self defence & martial arts... which Ive bought my fair share of I was pleasantly surprised with this Kindle download. Neal Martin the author is the real thing he has studied martial arts, done the doors and trained with some of the best martial artists & self defence Instructors out there. The detail in this book is amazing you get a true feeling that the Information in the book has been tested thoroughly and that it could in a "real life situation" actually save your life! Its not just for the Individuals that practice martial arts, or the door supervisors but anyone regardless of their ability or gender. A refreshing change from some of the Hocus Pocus martial arts stuff that is available.
