When I teach self-defense, I don’t separate the technique from the decision to use it. Knowing how to do something is only part of the equation. You also need to understand why you would do it, when it becomes necessary, and what may happen afterward. I’ve always combined those things together in the way I teach.

Part of that comes from my background. I spent almost a decade working in military law enforcement and anti-terrorism/force protection, and one of my responsibilities was teaching use of force. I’ve also spent decades teaching karate and self-defense to civilians. The circumstances are different, but many of the concepts are the same.

Use of force is not simply about knowing how to hurt someone. It is about understanding when force is justified, when restraint is the better choice, when de-escalation is still possible, and when circumstances may require an immediate and decisive response. Escalation is not always a neat progression from one level to another. There are circumstances where your first physical response may have to be severe, and in an extreme situation the force necessary to stop someone may result in their death. Those are not questions you want to begin thinking about after someone is already trying to hurt you.

Decisions Made in Advance

One of the things I used to tell students when teaching use-of-force concepts was that you don’t have time to figure everything out once things are already going bad. When the pressure is on, that is the worst possible time to be confronting these questions for the first time. Thinking you’ll simply figure it out in the moment is a mistake. If anything, that makes a bad outcome more likely.

Capability, opportunity, and intent were concepts I learned in law-enforcement training and later taught in my own use-of-force classes. Does the person have the capability to hurt you? Do they have the opportunity to do it? Have they demonstrated an intent to do so? Those questions help you understand what is happening and, just as importantly, help you explain afterward why you believed force was necessary.

The terminology and exact legal standards may differ for civilians, but the basic reasoning still carries over. What was the threat? Was the person capable of carrying it out? Could they do it at that moment? What were they doing that demonstrated their intent? Why did you believe you needed to act?

But self-defense does not necessarily begin when somebody throws a punch or grabs you. Situational awareness is something I believe many people take for granted. When I was in the military I spent enough time in hostile-fire zones that paying attention to what is happening around me became automatic. My wife and even my mother-in-law have commented on it. I’m not walking around expecting trouble, but I tend to notice people, movement, exits, and things that seem out of place.

That isn’t paranoia. Most of the time nothing happens, which is exactly what you want. But noticing a problem developing twenty feet away gives you options you may no longer have once someone is standing within arm’s reach. Sometimes the best self-defense decision is simply to leave before anything happens.

The purpose of thinking about these things ahead of time is not to decide exactly what you will do in some imaginary confrontation. Real situations rarely cooperate with plans that neatly. You just don’t want to be asking yourself these questions for the first time when you’re frightened, under pressure, and running out of time.

The First Battle Is Psychological

Years ago, while teaching karate at Valencia College, I had a conversation with a young woman in one of my classes that has stayed with me. We were talking about self-defense, and for women that conversation inevitably includes the possibility of sexual assault. I asked her a very direct question: “Do you believe you are capable of gouging a man’s eyes out if that’s what it took to avoid being raped?” To her credit, she didn’t give me the answer she thought I wanted. She stopped and thought about it, then said, “Honestly, no.”

I appreciated the honesty, because her answer told me something far more important than whether she could learn how to perform an eye gouge. She had just identified a line she was not prepared to cross, even under the circumstances I had described. That was something worth discovering while sitting safely in a classroom rather than during an actual assault. People say, “I’d do whatever it takes,” all the time.

The problem is that many fail to spend much time thinking about what “whatever it takes” might actually mean. Can you deliberately cause permanent injury? Could you blind someone? Would you break something? Are you capable of continuing to use force if the first strike fails? Could you potentially kill someone if that was genuinely what was required to stop them from killing you? Those are uncomfortable questions, and they should be. The point is not to make someone comfortable with violence. It is to force them to be honest with themselves before they have to make that decision for real. Knowing what you may be capable of under extreme circumstances is not the same thing as wanting violence. The point is not to become comfortable with hurting someone. It is to understand your own limits before fear and pressure force you to discover them in the moment.

Avoiding the Fight

The safest outcome is to avoid the physical confrontation altogether. If you recognize a problem early enough to leave, de-escalate, or create distance before anyone puts their hands on you, that is preferable to fighting your way out after it has already become physical.

That is different from violence that never involved you in the first place. If two strangers are fighting, I have no reason to make myself part of it. If the situation escalates or a weapon appears, that only gives me more reason to create distance and get myself and my family away from them.

Avoidance is not cowardice. It is simply recognizing that the best fight is often the one you never have to fight.

Stop the Threat

One principle repeatedly reinforced in my military law-enforcement and force-protection training was simple: the objective was to stop the threat, not to kill.

Sometimes stopping a threat means talking someone down. Sometimes it means restraint. Sometimes it requires immediate and decisive force. In the most serious circumstances, the amount of force necessary to stop someone could result in that person’s death, but death was not the objective. The objective was to make the threat stop.

A story that comes to mind involves a Kyokushin black belt from another dojo. He was on a business trip in Atlanta when a drunk man tried to start a fight with him in a club. It got pretty loud and the man’s friends were starting to gather around, so he left. Several people followed him into the parking lot, and eventually one of them put his hands on him. He punched the man a couple of times, but that wasn’t enough to stop him. So he changed tactics and started kicking him in the legs. It didn’t take long before the attacker lost interest in continuing. At that point, the Kyokushin black belt got in his car and left.

That is a good example of why I don’t like predetermined formulas for self-defense. He tried to avoid the confrontation first. Once it became physical, the first thing he did wasn’t enough to stop it, so he continued defending himself. When the attacker no longer wanted to continue, neither did he. He got in his car and left because the threat had ended.

Sometimes one action may be enough. Other times it may take considerably more. The amount of force needed is determined by what is happening in front of you, not by some arbitrary idea that one punch, one kick, or one technique should end the encounter. Once the threat stops, your use of force should stop with it.

The Problem With Untested Self-Defense

This is where I begin to part ways with a lot of self-defense instruction. There are people teaching self-defense who have never had to make decisions under serious pressure and who rarely expose their students to meaningful resistance. That does not automatically make everything they teach wrong, but it does mean many of their assumptions have never really been tested. Almost anything can look effective against a cooperative partner. Techniques work exactly as expected, the attacker responds exactly as predicted, and every sequence ends where the instructor intended.

Reality has a habit of being less cooperative. Someone grabs harder than expected. They resist. They don’t react the way you thought they would. You get tired. Your heart rate climbs. Your timing deteriorates. Something hurts. The first technique fails, and suddenly the entire mental script you had prepared no longer applies.

Weapons can change the problem completely. If shots are being fired, my ability to punch, kick, or throw someone may have very little to do with getting myself or my family to safety. Distance, cover, exits, and awareness may suddenly matter far more than anything I can demonstrate in a dojo. That does not make physical training unnecessary. Sometimes avoidance fails or there is nowhere to go. Other times somebody already has their hands on you. That is exactly why we train both sides of the problem.

Vulnerable Does Not Mean Guaranteed

One of the most common things I have heard over the years, particularly when women discuss self-defense, is some variation of, “I’ll just kick him in the groin.” The groin is absolutely a valid target. The mistake is believing that hitting a vulnerable target guarantees the end of the fight.

Men spend their entire lives instinctively protecting that area. Even when a strike lands cleanly, pain does not necessarily equal incapacitation. Someone who has spent years fighting full-contact learns fairly quickly that pain is something you can function through. You still feel it. It still hurts. But if pain automatically stopped you from functioning, you would never have been able to fight full-contact in the first place.

Years ago, I was sparring with a white belt when he accidentally kicked me in the groin. The interesting part was what happened next. He immediately dropped to the floor—not because I had done anything to him, but because in his mind he had just done something that should have dropped me.

I wasn’t upset with him. If anything, I was annoyed with myself. Anyone who has taught long enough knows beginners can be dangerous without meaning to be. Their adrenaline is up, and they’re too inexperienced to have good control over either the power or placement of their techniques.

I remained standing, looked down at him, and calmly asked, “Are you okay?”

He looked confused. “I kicked you in the groin.”

“Yes. Are you okay?”

“Yes.”

“Then get up,” I said.

I still remember the look of trepidation on his face as he got back to his feet.

I’m not suggesting the kick didn’t hurt. It did. But that wasn’t the lesson. He had already formed an assumption about what a kick to the groin was supposed to accomplish. Even though the kick had been accidental, in his mind the result should have been automatic: he kicked me in the groin, therefore I should have gone down. When I didn’t, his mental script suddenly flipped. That is the danger of building self-defense around assumptions. A vulnerable target is not the same thing as a guaranteed result. A painful technique is not necessarily a fight-ending technique, and the person attacking you does not have to react the way you expected.

Why Pressure Matters

My teacher used to joke that if you really wanted to know how tough you were, you should go into a bar, find the biggest guy there, and spit in his beer.

People laughed, but the point was serious. Real violence comes with consequences, and once you cross that line you no longer control everything that follows. Fortunately, we have much better ways to expose ourselves to pressure.

For most martial artists, full-contact competition is one of the best opportunities available to experience genuine physical and psychological pressure without the potentially life-changing consequences of real violence. A knockdown tournament is not a street fight, an arrest, military combat, or a sexual assault, and pretending otherwise does neither competition nor self-defense any favors.

What competition does provide is an opponent who does not want your technique to work. You have to function under physical stress, psychological stress, adrenaline, fatigue, pain, and uncertainty. You’ll discover whether you can still think while someone is hitting you and you will find out whether your timing survives pressure and whether you can adapt when the thing you expected to work doesn’t.

And that experience has value beyond fighting. Repeated exposure to controlled stress teaches you that you can still think while your heart rate is up and things are happening quickly. You become more accustomed to functioning through adrenaline instead of being overwhelmed by it. That does not mean competition prepares you for every possible emergency, but learning to remain calm enough to make decisions under pressure is useful almost anywhere things can go wrong.

“Karate is not a game. It is not a sport. It is not even a system of self-defense. Karate is half physical exercise and half spiritual. The karateka who has given the necessary years of exercise and meditation is a tranquil person. He is unafraid. He can even be calm in a burning building.” — Mas Oyama

Perhaps most importantly, training and experience will teach you that other people do not always react the way you expect them to. Competition does not reproduce real violence. What the experience can do is strip away some of the illusions you may have about yourself, your techniques, and the person standing in front of you.

How This Folds Into Karate

When I teach self-defense, all of these ideas are woven into the physical training. The how matters, but so do the why and the when. Teaching someone a technique without teaching them when it is appropriate, what it is supposed to accomplish, and what they should do when it fails leaves out too much of the equation. Avoidance matters. Awareness matters. De-escalation matters. Knowing when to walk away matters. In fact, my own preference is to avoid fighting whenever I reasonably can, precisely because I understand how quickly the consequences can become serious.

But avoidance is not the same thing as helplessness. There are circumstances where you may have no choice but to act, and in those circumstances you need to be psychologically prepared to use enough force to stop what is happening. Karate is not about looking tough or collecting supposedly deadly techniques. Self-defense is not about memorizing a collection of answers and assuming the other person will cooperate with them. It is about recognizing the problem early enough to give yourself choices, understanding what another human being may be capable of, and knowing what you yourself are willing and able to do if those choices run out.

You should not wait until someone is trying to hurt you to decide where your boundaries are. You should not wait until the first time someone resists to discover whether your techniques work against resistance. And you should never assume that because something hurts, the fight is over.

Pressure testing is valuable because it replaces assumptions with experience. Sometimes what it teaches you is about technique. Other times it teaches you about pain or fear. Competing in knockdown forces you to face the reality of fear. Pressure testing teaches you how to think while everything around you is moving faster than you would like. Perhaps most importantly, pressure testing teaches you about yourself.

“If you have no fear, you cannot look into your own heart. By overcoming fear, you are able to look into yourself. To look into yourself is to understand yourself. And to understand yourself is to know the way.” — Mas Oyama

In self-defense, that may be the most important lesson of all.
