About Mastering Krav Maga


Krav maga (“contact combat”) has become highly popular.  This instinctive self-defense system was developed by Imi Lichtenfeld to enable ordinary citizens to protect themselves against both armed and unarmed violent threats.  As instructors for the original non-profit Israeli Krav Maga Association, we have taught this simple, yet, amazingly effective world-renowned self-defense system to tens of thousands of civilians, professional athletes, law enforcement and military personnel as well as with celebrities.

Because not all krav maga is the same®, our foremost objective is to present and disseminate the self-defense teaching material properly.  The Mastering Krav Maga Online program is designed to teach and demonstrate both what krav maga is, and, equally important, what it is not – including the most common mistakes.  Many people equate krav maga as simply another type of exercise routine with a few self-defense mechanics thrown in.  No.  While there are many charlatan “instructors” doing krav maga a great injustice, legitimate krav maga is an instinctive, no-nonsense, and, when necessary, brutally effective self-defense system.   We do not suggest that we are the only ones who teach krav maga properly, but, we do it our way. In short, we believe this is the most evolved, comprehensive krav maga available. It has been tested against skilled adversaries and concerted resistance with the mindset that what can go wrong in violent confrontation will. We whole-heartedly invite the comparison of our (Gidon) method to other krav maga versions. Award-winning author and video producer David Kahn (trained under Grandmaster Haim Gidon), with the expert help of instructors Rinaldo Rossi, Don Melnick, and Chris Eckel and krav maga students, has created a comprehensive online training program for law-abiding citizens to master krav maga.  David serves as the Israeli Krav Maga Association’s (Gidon) U.S. Chief Instructor. This Mastering Krav Maga Online program provides 45 plus hours of training* (roughly 95% of the entire Israeli krav maga civilian curriculum) containing more than 380(+) updated individual and related lessons available to you 24 hours a day seven days a week.  This training will benefit both beginners and seasoned self-defense practitioners alike.

In short, this is krav maga as you have never seen it.

* Note, approximately 50% of the online lessons are the material from Mastering Krav Maga Volumes I, II, III and IV.  Belt levels have been added to each lesson.
