Welcome to Krav Maga Yashir Boston, teaching authentic Krav Maga direct from Israel.

Welcome to Krav Maga Yashir Boston, teaching authentic Krav Maga direct from Israel. Krav Maga is the official hand-to-hand fighting system of the IDF (Israeli Defense Forces), and is a proven and effective form of self-defense/defensive tactics. The system is designed to deal with real life violence, whether it involves single or multiple assailants, and includes solutions/techniques to deal with both armed and unarmed attackers.

Our program is run by Gershon Ben Keren, a 5th Degree Black Belt in Krav Maga, best selling author, and international trainer/instructor, who has trained civilians, law enforcement and military personnel globally.

Our program and training also looks at both the preventative measures that can be taken, to avoid being targeted as a victim in the first place (target-hardening), as well as ways to disengage and de-escalate aggressive and potentially violenc situations, along with instruction and training in how to deal with the physical consequences of a violent assault, such as injuries from knife and gunshot wounds etc. (our Tactical Medical program, which is provided free to students of Krav Maga Yashir Boston was features in the Atlantic after the November 2015 Paris Terrorist Shootings - click here to read). Our program will educate you as to how and why violent situations develop, how to assess and mitigate the risk of assault (both for you and your family), how to make decisions under high stress and duress, and how to physically deal with any assailant(s) in any situation (one-on-one violence, active shooter situations etc.). We also look at specific situations such as travel security, Terrorsim Awareness, and how to defend third parties such as partners and family members. This is not about martial arts, but about survival - and that is what we train for. Our program is comprehensive, realistic and has been proven to work in the toughest environments on the planet.

If you would like to book a free trial class please click here. Our classes are suitable for both men and women aged 17 + and require no previous training. Because we are not a competitive martial art or combat sport, our training in conducted in a supportive, non-egotistical and non-competitive manner. We take our training seriously, but we train together.

Our program is run and taught by Gershon Ben Keren, author of the critically acclaimed, “Krav Maga – Real World Solutions to Real World Violence” (Tuttle Press), and a 2010 inductee into the first Museum of Israeli Martial Arts (Herzliya, Israel). All of Gershon’s black belts and teaching certifications were gained in Israel, and he continues to return and train there in order to bring the most effective and up-to-date security and close combat training from the Middle East to Boston – we also bring some of Israel’s top instructors over to Boston to conduct seminars and teach classes.

Krav Maga Yashir Boston’s training is designed to prepare you for dealing with any and every type of violence you may have to face. In an ever changing world where new threats and types of violence are emerging there are few systems of combat that have proven themselves to be as adaptable and effective as authentic Krav Maga, that has been developed and evolved in Israel.

As well as teaching effective physical skills for dealing with violence, we also teach you the self-protection/security skills that will allow you to predict, prevent, identify and avoid violence before it occurs (to learn more about this please click here, or watch Gershon Ben Keren’s Google Talk on Krav Maga and personal security by clicking here). We also conduct tactical medical training, so that you can apply first aid either to yourself and/or others who may need such treatment after a violent assault or act of violence – to learn more about the tactical medical component of our training please click here.

Training at Krav Maga Yashir Boston, will change the way you think about violence, and provide you with both physical and non-physical solutions for dealing with all manner of dangerous situations. Our training is realistic, down-to-earth and non-sensational, and the environment we conduct classes in, is warm and welcoming.
