Krav Maga, Self Defense & Personal Safety

Gershon Ben Keren (Head of System for Krav Maga Yashir)started writing his blog in 2012, updating it weekly (and sometimes more frequently depending on events in the news, questions raised in classes, points brought up in seminars etc). Since then he has written 329 articles about personal safety, self-defense and krav maga. These have included articles on sexual assault, home security, street robberies, improvised weapons, school and adult bullying, situational awareness, CPTED (Crime Prevention through Environmental Design) etc. There are few areas of aggression, violence and personal safety, that he hasn't covered or touched upon.

The last four blog articles, that have been published, are displayed below. If you would like to visit the main blog site to read other articles, you can click on any of the months listed in the right hand side bar, or click here to go to

Situational Awareness, Mindfulness & Curiosity

(Gershon Ben Keren - Mon 21st Aug)

Sometimes when I talk to people about self-protection, they come away with the idea that those of us who think about our personal safety are in constant state of highly strung paranoia, jumping at shadows, and ready to decimate anyone who has the misfortune to approach us, outside of our field of vision. Sometimes, instructors promote this idea of “good” situational awareness, by telling stories about how their wife, friend, acquaintance, tapped them on the shoulder when they were distracted or deep in thought, and they turned ready to deal a death blow, only to recognize at the last moment that this person isn’t an enemy hell bent on their destruction. These stories are almost apocryphal in nature, and are terrible examples of what good situational awareness is, and only go to reinforce the view that to be aware of what is going on around us, we need to be in a constant state of high vigilance – when we recognize danger or harmful intent, this should be the state we enter, but it is not the state that allows us to recognize the danger in the first place; in fact it is likely to prevent us from identifying threats – we can consciously only process one thing at a time, so actively looking for signs of danger (before we’ve narrowed the threat down), is going to be an extremely inefficient and ineffective way of identifying harmful intent in our environment. I have found that it is this perception, of having to constantly think about danger, which is one of the biggest barriers for untrained people when considering risk, danger, and threats to their personal safety; they believe that their quality of life will drop, if they have to be constantly on the lookout for trouble. In this article, I want to look at the positive effects of good situational awareness, that go beyond keeping us safe.

One of the problems with modern living is that we are too comfortable, and too accustomed to our environments. We have lost the desire – and sometimes the ability – to be in the moment. Our familiarity with our surroundings and those in them, have caused us to completely switch-off, or actively look for something to distract us; such as reading something on our mobile phones. Our environments bore us, and we have stopped being interested in them. This isn’t just a problem from a personal safety perspective, it’s a problem with who we’ve become. We have lost the ability to enjoy the quality of the moment, and to be curious about the things around us. We shouldn’t be actively looking for danger, we should just be looking. A few weeks before I moved to the U.S. I was walking along the South Bank of the Thames in London – I often used to walk this route, as there was a company on Tower Hill, that I used to do some consultancy work for. This time, for whatever reason, I stopped, and looked across the river, at the London skyline. It was the first time I’d done so. In that moment, I began to realize some of the reasons why tourists came to the City; the skyline is an extremely impressive one. As I looked along it, I saw countless tourists taking photographs of it. They had a curiosity I lacked. The familiarity and the routine of the route, had taken me out of the moment. As “aware” as I thought I was, I wasn’t really aware of my surroundings. By being mindful in that moment, I increased my awareness. Good situational awareness doesn’t just alert us to threats and dangers, it increases our quality and appreciation of life.

When man first came down from the trees, and ventured out onto the savannah plains, he’d have been curious about everything. His survival depended on that curiosity. What did the new sounds he heard mean and signal e.g. the presence of prey that could be the next meal, or the proximity of predators that signaled danger, etc. Nothing could be or was taken for granted. This was a new environment and needed to be understood. This is the start of developing good situational awareness; understanding the environments that we exist in. If you were blindfolded, could you easily and quickly find the fire escapes at your place of work? This is an environment you probably spend an excess of 40 hours a week in, so this should be an easy one for you to do. Do you know where the nearest hospitals and police stations are on your way to work.? When you walk through the town or city where you live do you ever look up, or do you only look straight ahead? How well do you really know the physical environments, of the places you travel through, work in, visit etc.? We should be curious about our environments, so we can educate ourselves concerning them. This also allows us to live in the moment, and appreciate our surroundings, which is something we should be doing as living creatures.

Whenever I drive at night and park my car, I sit for a few moments with the lights off (central locking on), to let my eyes become accustomed to the darkness. This is something I started year ago, as a safety precaution, however I have seen wildlife that I would never have seen otherwise, and this has improved my quality of life. If I hadn’t taken these moments I would never have seen a young coyote play in the snow, which was extremely entertaining and life-affirming. Being situationally aware, involves being aware of everything, not just the things that can harm us, and this part often gets forgotten. Situational awareness means that you are living in that moment, and when we start to do that, not only do we become safer, but our quality of life goes up. Being aware does not involve being fearful, or constantly imagining the dark thoughts that others may be having towards us. This would be both exhausting and depressing. It involves living in the moment, something which will make our lives both safer and more enjoyable.

(Gershon Ben Keren - Mon 14th Aug)

In real-life confrontations, stances – as stances – rarely exist. If you have time to adopt a “Fighting Stance”, like an MMA fighter, at the start of a bout, you will have missed an opportunity to attack your aggressor. In violent incidents,  there is no referee, telling you when the fight will start, and if you have the time to get into a stance, you obviously recognized that the situation was turning physical, and therefore you should have made a pre-emptive assault, instead of getting into a position which sees you waiting for your aggressor(s) to attack you. If you were taken by surprise – which you shouldn’t have been, if you are aware of your surroundings – you won’t have the time to get into a stance, you’ll be blocking and moving, and trying to play catch up on what has happened to you. In this article, I want to look at the role stances play in real-life confrontations, their relevance and use, and what they can teach us about fighting.

I strongly oppose the notion that Krav Maga is MMA for the street. This isn’t about rules, and what techniques are effective or not; that’s another debate/discussion. The format of an MMA bout, bears little resemblance to a real-life confrontation – real life violence is non-consensual, and occurs without warning. There is nobody there to start (and stop) the fight, and combatants generally start nose-to-nose, without the luxury of distance. From a fighting perspective, there isn’t an opportunity to get into a stance, you are simply fighting from the moment things go physical. However, there are occasions, during the verbal confrontation, that precedes most physical confrontations, when you do have the time and space - and should adopt a stance - but it won’t be your “fighting stance”.

Anyone who has worked in some public-facing form of security, will have found, or been taught a stance/position, where they don’t look aggressive, but are ready to act. On many CP (Close Protection) courses, you are taught to stand, with arms half-folded – the idea being that you appear non-threatening, but have a free hand that can be used, to push, grab and make quick distracting strikes, etc. Personally, I liked to put my hands out in front of me, palms somewhat down in an Interview/De-escalation Stance. I’d normally, “talk” with my hands, moving them as I spoke, so that if I had to go pre-emptive, my hands were already moving, and were less likely to cause a reaction from the person I was dealing with. If in these situations, if I’d pulled a “traditional” fighting stance, with my hands coming up to guard my face, I may well have been viewed legally as the aggressor, and seen to have committed an assault i.e. I was in a position where I could cause harm to the person I was dealing with, and would have given them a reason they should fear for their safety. Forgetting any legal perspectives on the “Fighting Stance”, if they had a weapon on them, they may now feel threatened enough, and feel justified, to use it. Adopting a “Fighting Stance” during a social interaction is only going to escalate things, and let your aggressor know where your intent is.

So, what is the purpose of a “Fighting Stance”? It is there to teach concepts and principles. A fight is a dynamic thing, and you need to be mobile in all directions, so your weight needs to be divided equally between both feet – as you move, not as you stand there. Obviously, if you are striking, weight transfer will occur, though it should never result in more than 60% of your weight being loaded onto the front foot – something worth checking, next time you throw a straight rear-hand punch/strike (if you can lift your rear foot from the floor as you strike, you should look at centering the weight in your hips, by sinking them). Fighting is about moving, and a “Fighting Stance”, should teach you how to move.

When you move, you need to be stable, and able to generate power. Many people confuse stability with balance. The individual who throws their rear-hand punch, with everything they’ve got, loading 90% of their weight onto the front foot is balanced, but they are not stable – they are effectively standing on one leg. A “Fighting Stance”, should teach you the importance of keeping your head over your shoulders, and your shoulders over your hips i.e. not to lean, whether you're moving backwards or forwards. It’s not so much a stance, as a lesson on what to do when you are moving.

In a fight, both hands should always be active. The idea that you will ever simply have your hands up in a static position is erroneous – they should be doing something; preferably striking. There really shouldn’t be a time when they are both up, simply guarding your face. This mistake often gets made, when people confuse sparring with fighting. Sparring has many merits, however it shouldn’t be looked on as replicating a real-life fight. Sparring is something you and a partner do together, a fight is something you do to each other i.e. my aggressor is trying to violently assault me, and I am trying to violently assault them – the fact that I am doing this in order to defend myself is a secondary concern. A real-world confrontation sees somebody coming at you, there really aren’t moments when you are circling each other in stance – if there are, why aren’t you attacking in these moments? Fighting should be a zero-sum game, if your attacker isn’t doing anything to you, you should be doing something to them – you shouldn’t be giving them the time and space to recover and maneuver.

We need to stop confusing real-life violence with combat sports. We need to recognize the format of violent confrontations, and understand the purpose of the “stances” we teach from, and practice in. There should be no static elements in a fight – we should be moving and attacking, or at worst moving and defending, in order to set up our attacks.

Elephants In The Room

(Gershon Ben Keren - Mon 7th Aug)

Often, when people with little understanding of what real-life violence looks like - because they have been fortunate enough to never experience it first-hand - try to imagine incidents, situations and scenarios, they build their “models of violence”, from the media, the movies, and third-party anecdotes, imagining that common armed criminals such as muggers, are at some point looking to, “complete the task of termination”, rather than simply exit the environment with your wallet. A rich diet of action movies, and extreme news stories, can distract us from the reality of violence – which is more likely to comprises of pushes, shoves, grabs and punches, than assassination attempts. In this article, I want to look at some of the elephants in the room that often don’t get discussed in self-defense classes, and some common misconceptions around violence.

There is a tendency when teaching techniques to remove the context e.g. a knife defense gets taught, without an explanation as to why somebody is making the attack in the first place – when we introduce the attacker’s motive into a scenario, we can understand much more about the when, where and whom of assessing risk. One of the other five situational components, that features in a violent confrontation, is relationship i.e. what is your relationship with your assailant? It is often implied – or sometimes explicitly stated – in self-defense scenarios that our attacker is a stranger, however this does not reflect reality, where we are statistically more likely to be assaulted by someone we know; and when we look at particular demographics such as children, this is especially true. There is a value to teaching “Stranger Danger”, and other similar programs, but we are fooling ourselves if we think we are addressing the danger of sexual assaults on children, when they are far more likely to be committed by family members and their friends. If our child safety programs don’t reference this, it would be wrong to think of them as being truly comprehensive.

Even when we are presented with the facts and statistics, it is all too easy to think that they don’t apply to us. In a now-famous study concerning how we apply statistics to ourselves, there was a survey that consisted of a number of factual statements, where participants were asked to state their opinions, thoughts and ideas about them. One of the statements/questions was, “The average life-expectancy of a US Citizen is 88 years old. How old do you expect to be at your time of death?” Nobody answered 88 or younger, everybody believed that they would beat the statistic; that it didn’t apply to them. We can argue to ourselves that we, personally are most likely to be assaulted by a stranger, however we are part of the statistics that say this isn’t the case. We do a huge disservice to our female students, if we present rape and sexual assault scenarios in the context of strangers, making surprise attacks from the rear; when in fact most rapes involve people the victim knows, and occur in their home or somebody else’s.

Most violence happens face-to-face, and is preceded by dialogue. A subjective study will confirm this. How many verbal altercations and disputes have you seen, versus physical fights? How many physical fights have you seen – from the starting point, not having walked in on – that didn’t start first with a verbal confrontation? Do sneak and surprise attacks happen? Of course, and we need to train for them, however we also need to train to deal with violence from “conversation” range, and from the standpoint that there are things we can do to better our chances of surviving such altercations during this phase of the fight (the Pre-Conflict Phase) e.g. controlling range, bringing our hands up in a placating manner, attempting to de-escalate the situation (if it’s spontaneous in nature), etc. If we train from the perspective that people just attack/punch us, out of the blue, and that’s what is most likely to happen to us, we aren’t training for reality. Most violence is low-level, that occurs spontaneously, and can usually – with the correct training - be de-escalated. One good way to stay on track and make sure we are training realistically, is to introduce “motive” into everything we teach; why is the person targeting us, why have they chosen to be violent towards us? Is it something we’ve done? Is there something they want? If every time we teach or learn a technique the motive of the attacker is introduced, we will quickly see if we are creating contrived, and unlikely scenarios.

When we consider that most violence happens face-to-face, and is preceded by dialogue, and recognize that the person who initiates the physical confrontation will have the advantage, we really have to teach and/or practice pre-emptive strikes and attacks. If you are in fear for your safety, and your attacker is in a position to cause you harm, then you are being assaulted, and you have the right to defend yourself (under US law), and that includes being the one who makes the first strike. Don’t be fooled into thinking that this is school, and the guilty person is the one who “started” it. If you have the opportunity presented to you to make the first strike, and put your assailant in a position where they are the one who is reacting, don’t pass it up. Be aware of what would constitute reasonable force in such a situation, and don’t pass up on an opportunity to disengage, and get to safety, because you’ve been lead to believe that in every situation you need to fully incapacitate your assailant – not being there is, in most cases, the safest strategy. If you believe that your attacker might eventually pull themselves together and come hunt you down, you’re most likely confusing yourself with Jason Bourne.

Reality Based Self-Defense, means basing what we teach on reality – how real-life altercations actually occur, not simply what we imagine them to look like. We should not be trying to create realities which don’t exist or are unlikely, just because they “could” happen; anything could potentially happen, and we need to put aside our flights of fancy, to be grounded, and to teach, train, and practice for the real-life situations we are actually likely to face.

Applying Risk Management

(Gershon Ben Keren - Mon 31st Jul)

A core component of self-protection is risk management and mitigation – whenever I do any form of consultancy, this is where I always start. I’ve written in more depth about what risk is, and how to define it. In short, risk is where assets, threats, and vulnerabilities intersect; e.g. where there are no threats and vulnerabilities, there is no risk to our assets (which can and does include us). It is virtually impossible to live in a world, or act and behave in such a way, that there is no risk; as soon as you leave your house, you become more vulnerable to attack – and the risk to your safety goes up - because you lack the protection of your home. One way to mitigate and manage this risk, is to never leave your house, but obviously that would be both an impractical and unhealthy solution to dealing with the risk, especially when there are other practical and simple ways to reduce vulnerabilities, and often the opportunity to limit your exposure to threats and dangers e.g. don’t go to a bad part of town late at night, etc.

One of my students relayed a story about a female friend of his, who believed somebody was following her. She approached a man on the street, and asked him if he would walk with her, until she got to her house. He refused. Amongst my student’s group of friends, there was a sense of moral outrage, about the man’s refusal to assist, and the emotional part of me agrees. However, the objective risk-mitigator/manager in me sees things differently. Obviously, those friends of the woman, knew that her story was genuine; that she felt she was in danger, and approached somebody whose presence would deter the person following her, to walk her home. To the person being approached, they have no idea what the back story to the incident is e.g. is the person following her an ex-partner who is jealous that she is seeing other people (and could be armed), is she part of a gang that is using her to lure targets/victims to a location where they will be mugged, abducted, etc? What are the risks, and the level of those risks, involved in walking this person home? And are we prepared to accept them, because the cost/risk to the person asking for assistance is potentially greater? Most of us, I believe, would accept these possibilities, to do what we would see as the “right thing”, but at the same time, we shouldn’t do this blindly, in case by doing so, we are putting ourselves in danger . We should gather more information.

We need to understand the “threat” portion of the assessment more fully, and we can gain more information concerning this, by asking questions e.g. does the person know the individual following them? If so what is their relationship? Where were they coming from, and when did they notice/realize that somebody was behind them? If it’s the crazy ex who saw her in a pub or bar, and has decided to follow her home and confront her about something – and he has a history of violence – walking her back to her house may not be the safest strategy for either of you; especially if she has just moved in order to avoid him knowing where she lives. Just because somebody asks for help, doesn’t mean that the help they are requesting is effective help. They could be making the situation worse for themselves, as well as you. In this scenario going to another place of safety, would be a better strategy. As part as your own personal self-protection planning, you should have safe places you can go to – apart from your home – when you find yourself having to deal with a threat. These can be friend’s houses, well populated places, police stations and hospitals, etc. If the woman you were trying to assist believed she was in imminent danger, there may be places of safety closer to you both than her house.

There is a terrible poster campaign running on Boston’s subway network. It is well intended, but poorly executed. It involves intervening on another person’s behalf, when they are having to deal with an aggressive individual. In it, a white man is shouting aggressively at a Muslim woman, who is sitting in a subway car. The poster advises that you should intervene, by going up to the woman, sitting next to her, and starting a conversation, about the weather, movies, etc. The misplaced belief is that the aggressor, who is now being ignored, will walk off frustrated. It’s a lovely idea, but ignoring someone who is emotional and angry will, in most cases, only escalate the situation. The poster was designed by a French artist – there is a reason I don’t give drawing lessons, and there is a reason why artists shouldn’t be given well-intended, but misplaced/misunderstood advice about de-escalation. When you accept a risk, such as intervening on somebody’s behalf, you need to make sure that you have the “tools” to do the job, or you may make the situation much, much worse, increasing the risk of violence, both to yourself and the person you are helping (I have written articles on more effective strategies for intervening in such situations – you can use the search box on, and type in the search term “intervening” to find them). Are you prepared for a violent confrontation, if/when the aggressor doesn’t walk away, but instead gets physical?

We can mitigate risk, by having the correct tools to deal with a situation. A large part of risk management is reducing our vulnerabilities – those things which a threat can exploit, either directly or indirectly. Often, our vulnerabilities come from ignorance and misguided advice about what violence is, and how we should handle it e.g. when we are in the presence of an aggressive individual we might think we should pretend to be on our phone, and that they will respect the social convention of not interrupting a conversation – a predatory individual who is looking to cause you physical harm, has already ignored perhaps the greatest social convention of all; being perceived as impolite is not going to deter them. Neither are they going to be deterred by the fact that somebody else might know where you are – they know that the assault will be over before any assistance can reach you.     

We may choose and believe that walking the woman home is an effective strategy, but as we gain more information about the situation, we should be flexible in taking it on board, and changing our strategies for dealing with it. Understanding what the threats and vulnerabilities are in a situation allows us to make informed and rational decisions, rather than emotional ones. Most of us want to do the right thing, and will accept a certain level of risk that comes with that, but there may be ways we can do this, while limiting both our vulnerabilities in the situation, along with those of the person(s) we are trying to help.
