No matter if this story is true or not - this is what happens with this book and the pure krav maga system in comparison with other self-defence-systems and martial art. If one wants to learn self-defence he or she can learn it in an "inefficient, complicated way" or: reads this book and visit pure krav maga lessons. It is the most simple and efficient way to learn self-defence.
I am (after 10 years material art experience) surprised how easy it is - or let's say how easy it is to learn it - to defend my life. (it would have been luck to know it 10 years ago!).
Really fascinating! In short - this book is an absolute must-have! The pure krav maga system is brilliant and everybody - men and women (!) should know it!
Small notice: just ignore the books' layout... it's not really good. Tough the content is - it is really perfect. A little bit like all substance, no show...
