Book A Free Women's Self Defense Class

Welcome to Women's Self Defense Boston. We offer FREE self-defense training (our course and classes are completely free) to women living in Massachusetts - every Saturday 10:00 am to 11:00 am. There are no commitments, no hidden costs etc our classes are 100% free. We teach Krav Maga Yashir a self-defense system developed in Israel that is used by the IDF (Israeli Defense Forces); our approach is instinctive, direct and highly effective. You can book a class by going to the calendar at the bottom of this page.

We break self-defense training down into two parts. The first part is what we term "Self Protection"; this is all the head knowledge, non-physical strategies and tactics you can use to avoid and predict violence (our program is based on the SEPS - Situation Effective Protection System - approach that aims to educate individuals as to the motivations and dynamics of violent situations). The second part is the physical self-defense component i.e. what happens when you can't predict or avoid violent behavior and need to physically deal with an aggressor/assailant. This part is based on Krav Maga Yashir - an Israeli martial art that has the aim of Survival (Hisardut is the Israeli term for Survival) as its goal.

Why do we offer this program as free? Our aim is not to give any women in the Massachusetts area a reason for not spending some time learning how to protect themselves - and those they have responsibility for. We feel this responsibility and believe you should feel it for yourself.

We will teach you how to predict violence, understand the verbal cues and methods that predatory individuals use. We will educate you as to the warning signs regarding potential partners who may end up becoming obsessive, manipulative etc and eventually stalking you. We will train you as to how to deal with physical assaults and develop a survival mindset that will keep you fighting when your natural inclination is to give up. These are not empty words or promises and because we are not "selling" you anything you can be assured this is not a sale pitch.

You will be hard pressed to find a classes that are a comprehensive in their approach to handling violenec or instructors who have a similar pedigree. Head Instructor of the school is Gershon Ben Keren, a 3rd Degree Black Belt in Krav Maga Yashir, a member of the Israeli Museum of Martial Arts, a National Judo Champion and a Martial Arts Hall of Fame Representative. An instructor with over 20 years experience teaching civilians and elite law enforcement/military individuals etc.

Our program is "Scenario Based" in that we don't just teach technique(s) we teach the application of them i.e. when they will be effective, when they shouldn't be used and when various situations will color their use. Our program is an education into violence not simply a "how to" of self-defense.

We use "Redman" Scenario based training suits - these are the protective suits you see in the photos (and which are used by military and law enforcement trainers) - which allow us to use "real force" when training without the risk of injury etc. This is one of the things which makes our training both effective and realistic and allows us to blend the "Self Protection" piece seamlessly with the "Self Defense" piece.

If you want to register your place for an introductory class (you only have to do this once) please use our online booking system below - you have the opportunity to book/try out one of our regular self-defense classes as well. Our Women's Self Defense program is every Saturday 10:00 AM to 11:00 AM. Once you have booked you will receive instructions in your confirmation email.

Book A Class

Each person who is wishing to attend a class for the first time, must book i.e. no group bookings. You need do this only once. After booking you will receive a confirmation email. If you later need to cancel your class, you will find a link in that email. We limit the number of "first timers" in each class, to ensure that everyone has a good experience of the training therefore failing to attend a class without cancelling could be denying someone of a place. The only Saturdays there are no classes for first-time students is when we are conducting Redman Training sessions (or on Federal Holidays). For more information about Redman Classes please click here.

Unfortunately we are unable to provide childcare solutions, and whilst we recognize the difficulties this may provide to women wanting to attend, as a free program, with no outside funding we do not have the resources to provide professional childcare for the children of women attending our classes - neither can we allow unsupervised children to be in our gym area/space whilst these classes are running. If this prevents you from attending you can access all of our course materials for these classes by clicking here
