Ok unlike Karate or Kung Fu, Krav Maga doesn't rely on strength or good co-ordination, the art is based upon the body's own reflexes in certain situations, and it uses these reflexes and turns them into self-defense techniques. This book also has good chapters on weapons, drills and some good real life stories of true life-or-death situations. Its relatively easy to pick up and remember and if nothing else gives you a good understanding of how to react when faced with a knife or gun which in this chav-wannabe-gangsta day and age we live in is a possibility. You even get taught how to rescue hostages and stop a grenade being let off. I think this book is excellent for doormen, police or armed forces people who have to deal with this sort of stuff all the time. Don't let Michele Ryan stumbling about in the Bionic Woman put you off, Krav Maga is anything but girlie.
