Krav Maga, meaning "Contact Combat" in Hebrew is a generic term given
by the IDF (Israeli Defense Forces), to refer to the close combat and fighting programs its various
instructors run. Rather than there being one particular and distinct Krav Maga program, each instructor
is given a degree of flexibility and autonomy to teach according to the needs of the unit he is training,
at that particular time. Krav Maga Yashir Head Instructor, Gershon Ben Keren, has trained with some of
Israel's top Krav Maga instructors and received his Black Belts and teaching certificates in Israel from
them. He continues to train in Israel and brings back authentic, effective, and more importantly proven
Krav Maga techniques to his school in Boston. Our Krav Maga training comes direct from Israel and has been proven
effective in one of the world's toughest and most violent environments - this is why Krav Maga can be relied
upon to deal with the real-life violent altercations that you may potentially face. The fact that Krav Maga has
been tested by a large number of military personnel means that it has performed consistently well for a
variety of body types and athletic abilities and so can be relied upon by any practitioner of the system.
Krav Maga Yashir refers to the distinct system of Krav Maga that is taught at our Boston school, a 16 000 sq ft
facility, which is the largest dedicated Krav Maga training facility on the U.S. East Coast. Yashir in
Hebrew means "Direct" and emphasizes our Krav Maga system's, no-nonsense approach to ending violence quickly. Our system
is suitable for men and women with no previous martial arts experience (and all fitness levels), and is
designed to get the novice or beginner to a high state of proficiency in the shortest possible time. We teach
techniques according to principles and concepts, rather than just straight repetition. This speeds up and
enhances the learning process.. Read more about our Krav Maga system by clicking here and/or watch some video clips of DVD's and
classes by clicking here.
Our techniques, like those taught in Israel, are based on natural defensive, reflexive actions - things that
the body will naturally do when attacked or threatened (such as flinch, pull back the hips, grab an attacking
arm, etc.) Krav Maga is based on the idea that you should train according to the way in which you will actually
respond and act when assaulted, not how you would like to or think you should. It is virtually impossible to
un-train the body's evolved natural responses, and is therefore better to work with them than against them.
This is the essence of Krav Maga training and the method we teach in our Boston School.
There are many self-defense and fighting systems that are designed for specific environments or situations,
but few that train you to adapt to the situation you are in and make effective decisions when in them. Krav
Maga training is not just about learning techniques but equipping you with the knowledge of when and how to
apply them (or whether to choose disengagement or de-escalation as a strategy). It is this empowerment that
makes Krav Maga distinct from many other fighting/self-defense systems. If you would like to book a
free trial Krav Maga class, at our Boston school to get a taste of our unique approach to reality based self defense please
We train hard and take what we do seriously but do so in a safe, inclusive and welcoming environment. When you come
down and take a class with us our Krav Maga Instructor Team will do everything to answer your questions and concerns. If you
have any immediate queries, please feel free to go to our

Gershon Ben Keren's Book Available For Pre-Order
Gershon Ben Keren's comprehensive introduction to Krav Maga is now available for pre-order on Amazon. This book
is not simply a disparate collection of techniques but demonstrates Krav Maga as a comprehensive fighting and
self-defense system using the concepts and principles upon which it's based.
All of the photos in the book were shot in real-time, demonstrating what realistic movements-both from the attacker's
and defender's perspective-look like. Where applicable, techniques have been shot in the scenarios in which they occur
such as bars, restrooms, ATMs, etc. The situational components of such violent incidents are explained, so the reader
can learn to identify, predict, and avoid violence before it occurs.
Gershon Ben Keren is a 3rd Degree Black Belt in Krav Maga who received both his training, black belts and instructor
certification in Israel.

Krav Maga Boston - Testimonials
I can honestly say that I've never had a higher standard of instruction in my life. That includes anywhere in
the military including instructors from special forces. There aren't many people you come across in your life
who you can genuinely call a teacher and Gershon Ben Keren is one of them. Not just because of his technical skills or even experience in the street,
as many people have that but due to his deep understanding of why things work and more importantly why things don't"
Short version: Krav Maga Yashir offers a combination of physical challenge, team cameraderie, and an expertly instructed reality-based
self-defense system that blew my initial expectations out of the water. As a young professional and Marine Corps infantry veteran I have high expectations and a disinclination to waste my time, when it comes to any activity that I am going to invest significant money and energy into. My membership here has not disappointed in the least. "
