About Instructor Gershon Ben Keren: Krav Maga Expert and Israeli Martial Arts Authority

Gershon Ben Keren is a 5th Degree Black Belt in Krav Maga with over three decades of training and teaching experience. He has been practicing Israeli Krav Maga since 1993, developing deep expertise in this combat system over more than 30 years of dedicated study and instruction.

In 2010, Gershon Ben Keren was inducted into the Museum of Israeli Martial Arts in Herzliya, Israel, recognizing his significant contributions to preserving and teaching authentic Israeli self-defense methods. This honor places him among a select group of martial artists recognized for their expertise in Israeli combat systems and their role in transmitting these techniques to international audiences.

As the head instructor of Krav Maga Yashir Boston, Gershon Ben Keren brings direct Israeli Krav Maga lineage and authentic training methodology to students throughout the Boston metropolitan area. His instruction emphasizes the original purpose and application of Krav Maga as a functional self-defense and combat system rather than a fitness-oriented workout program.

Core Philosophy: Working With Natural Responses to Violence

Krav Maga Yashir is built around simple, direct movements that align with the body's natural instinctive responses when confronted with sudden violence or physical threats. Unlike martial arts systems that require practitioners to override natural reflexes, Krav Maga Yashir works with instinctive reactions rather than against them.

This approach to self-defense training recognizes that during violent encounters, the body automatically responds in predictable ways due to adrenaline, fear, and survival instinct. Rather than attempting to suppress these natural responses, Krav Maga Yashir teaches students to:

Recognize natural defensive reactions - Understanding how the body instinctively responds to threats
Refine instinctive movements - Developing natural reactions into more effective defensive techniques
Progress to advanced techniques - Building from basic instinctive responses to sophisticated combat skills
Apply techniques under stress - Training realistic scenarios that trigger natural stress responses

From these fundamental natural reactions, students gradually develop more advanced and effective self-defense solutions including throws, takedowns, joint locks, control techniques, and sophisticated striking combinations.

Civilian Self-Defense Adaptation: Legal and Practical Application

Although Krav Maga originated as a military combat system developed for the Israeli Defense Forces (IDF), Krav Maga Yashir has been carefully adapted for civilian self-defense applications in the United States. This adaptation ensures that training is:

Legally Appropriate - All techniques and training scenarios are designed to be consistent with U.S. self-defense law, including:

Proportional response to threats
Understanding use-of-force continuum
Reasonable force standards
Legal aftermath considerations
Documentation and reporting requirements
When to engage versus when to escape
Proportionality and restraint
Legal and ethical use of force
Protecting others while managing personal risk

This civilian adaptation distinguishes Krav Maga Yashir from purely military-focused combat systems, making the training practical, legal, and applicable for everyday personal protection needs in Boston and throughout Massachusetts.

Comprehensive Threat Defense Training

Krav Maga Yashir students learn defense against both unarmed attacks and armed threats, preparing for the full spectrum of violent encounters civilians may face:

Unarmed Attack Defense:

Punches and strikes from various angles
Grabs, holds, and restraints
Chokes and strangulation attempts
Pushes and shoves
Hair pulls and clothing grabs
Bear hugs and body locks
Ground attacks and pins

Armed Threat Defense:

Knife defense - Defense against knife attacks, threats, and edged weapons
Firearm defense - Gun defense including short-barrel weapons (pistols, revolvers) and long-barrel weapons (rifles, shotguns)
Stick and baton defense - Defense against impact weapons and blunt objects
Improvised weapon threats - Defense against bottles, tools, and other makeshift weapons

Multiple Attacker Scenarios:

Awareness and positioning against multiple threats
Target selection and movement strategies
Managing multiple attackers simultaneously
Escape and evasion tactics
Environmental use for tactical advantage

Positional Defense Training:

Standing defense - Techniques from normal standing positions
Seated defense - Defense while sitting (vehicles, restaurants, offices)
Ground defense - Fighting from ground positions, getting up safely
Surprise attacks - Defense when caught off-guard or ambushed
Prepared defense - Techniques when a person is aware of an impending threat

This comprehensive approach ensures Krav Maga Yashir students can defend themselves effectively regardless of the specific circumstances, attacker profile, or environmental constraints they encounter.

Beyond Physical Techniques: Violence Prevention and Awareness

Krav Maga Yashir goes significantly beyond teaching physical self-defense techniques. Equal emphasis is placed on non-physical skills that often prove more valuable than fighting ability in maintaining personal safety:

Violence Prediction and Recognition:

Pre-assault indicators and behavioral cues
Threat assessment and risk evaluation
Understanding criminal selection processes
Recognizing dangerous situations before violence occurs
Body language and verbal warning signs

De-escalation and Conflict Management:

Verbal de-escalation techniques
Non-threatening body language and positioning
Communication strategies to defuse aggression
Boundary setting without escalation
Managing ego and emotional responses

Avoidance and Prevention Strategies:

Situational awareness training
Environmental scanning and threat detection
Safe movement through public spaces
Travel safety and route planning
Alcohol and social situation management
Understanding that violent encounters don't occur in isolation

Contextual Understanding:

How violence actually develops in real-world scenarios
Criminal psychology and attacker motivations
Social dynamics that lead to violence
Environmental factors that increase or decrease risk
Legal considerations before, during, and after incidents

This holistic approach to self-defense recognizes that the best fight is one that never happens, and that awareness, prevention, and de-escalation are the first and most important lines of defense.

Environmental Awareness and Improvised Defensive Tools

Krav Maga Yashir training includes effective use of the environment and identification of everyday objects that may serve as improvised defensive tools during violent encounters:

Environmental Tactical Use:

Using walls, corners, and barriers for protection
Positioning relative to exits and escape routes
Leveraging furniture and obstacles
Creating distance using environmental features
Terrain awareness (stairs, curbs, uneven surfaces)

Improvised Weapons and Defensive Tools:

Keys, pens, and everyday carry items
Belts, umbrellas, and accessories
Bottles, chairs, and common objects
Bags and backpacks for blocking or striking
Cell phones and flashlights
Environmental objects (rocks, branches, etc.)

This training component ensures that students understand self-defense isn't limited to empty-hand techniques but can leverage available resources to improve defensive capabilities and increase survival chances during violent encounters.

Authentic Israeli Krav Maga Training, Not Fitness-Focused Workouts

While many Krav Maga schools in the United States and throughout Boston have shifted to presenting Krav Maga primarily as a fitness workout or cardio class with martial arts themes, Krav Maga Yashir continues to be taught as a functional fighting system and legitimate self-defense training, consistent with Krav Maga's original purpose as a combat system.

Krav Maga Yashir Prioritizes:

Effective self-defense techniques over calorie burning
Realistic scenario training over choreographed routines
Combat effectiveness over workout intensity
Technical skill development over exercise repetitions
Violence education over fitness entertainment
Functional application over aesthetic movements

While physical fitness naturally improves through Krav Maga Yashir training, fitness is a beneficial side effect rather than the primary focus. Students training at Krav Maga Yashir Boston are learning authentic Israeli self-defense methods designed to work in real violent encounters, not participating in martial arts-themed fitness classes.
