“Darren Levine has my unqualified support and gratitude for his contributions to Krav Maga.”
--Imi Lichtenfeld, founder of Krav Maga

This was the book recommended to me by when I took my instructor training course in 2011, I now have over 80 books on training in my Krav Maga and self defence training library and I still feel that it's one of the best out there. 

When we challenge the status quo, we test our skills and we challenge ourselves and others towards improvement. I have worked in office where I have asked "Why is it done like that?" and too frequently the answer has been in the region of "That´s just the way we work", or even worse... "That's the way it's always been done".
These are the answers of people who do not understand the reason why. If you cannot articulate the understanding, then you don not know it well enough.
