When a Technique Gets Blocked: Learning to Adapt

Learning a martial arts or self-defense technique is relatively straightforward. A teacher shows you what to do, you practice the movement, and eventually you can make it work.

But what happens when the other person doesn't react the way you expected?

They may resist more strongly, block what you are doing, move differently, or counterattack. A technique that worked perfectly a moment ago can suddenly stop working.

This is where simply knowing more techniques is not necessarily enough. You also need to learn how to adjust when the situation changes.

Bruce Lee famously used the image of water to describe adaptability: rather than becoming fixed in one shape, change according to what you encounter. It is a powerful idea, but it also raises a practical question:

How do you actually train someone to become adaptable?

In Functional Wing Chun, one way we train this is by first allowing a technique to work, then deliberately adding resistance or a counter and asking the student to find a way to continue.

The basic progression looks like this:

WORKS → BLOCKED / COUNTERED → ADAPT → WORKS → CONTINUE → FINISH

Adaptation, however, is not the goal of the exercise. We are not trying to become endlessly creative or demonstrate how many different solutions we know. If fighting has become unavoidable, the overall objective remains much simpler:

Finish the fight as quickly as possible.

Adaptability is one of the things that helps us do that. When the opponent stops the route we originally chose, we need to be able to adjust without unnecessarily giving up the initiative and starting again.

First, we need a direction

Perhaps the student begins with a Pak Sao and punch. The teacher demonstrates it, the student learns the basic movement, and against the initial response it works. That gives us a starting point—a direction toward the objective.

Adaptability does not mean standing in front of someone waiting for random things to happen and then trying to react to each one. We initiate first. The opponent then gives us something real to adapt to.

The technique provides the first route.

What happens when the opponent tries to close that route is where the next part of the training begins.

Then the opponent resists

Once the first version works, the training partner changes what they are doing. Maybe they block the punch, change the position of the arm, counterattack, or simply find a way to stop our progress. Something that worked a moment ago now fails, or at least no longer works in exactly the same way.

One possible response is to add more strength and try to force the original movement through. Sometimes that may even work, but it teaches us very little about adaptation. The opponent's resistance has changed the situation, and importantly, that resistance often creates contact. The contact gives us information.

Through that contact, we can begin to feel where our progress is being stopped, where the resistance is coming from, and sometimes where the opponent has created a new opening by trying to close another one. Instead of blindly insisting that the original technique must still work, we can use that information to change what we are doing.

Adapt to the resistance

The adjustment does not always need to be large. Perhaps the hand changes direction, our position shifts slightly, another hand becomes available, or the opponent's attempt to stop us exposes a different route forward. The exact solution is less important than learning the process of recognizing what has changed and responding to it without losing sight of the objective.

This is why adaptability is different from simply collecting more techniques. We are not trying to memorize one predetermined answer for every possible counter. We are learning to recognize resistance, understand what it is doing to our progress, and find a way around it.

The objective remains. The resistance changes. So the route changes.

Adaptability is not the destination. It is a means of continuing when the route we initially chose is no longer available.

When it works, continue

This is why the next part of the sequence is so important: CONTINUE. If our adaptation succeeds, we do not automatically stop and reset simply because another movement worked. The fight may not be over, and the overall objective has not necessarily been achieved.

This connects directly to one of the ideas we use throughout Functional Wing Chun: Identify. Clear. Continue. Identify what is stopping your progress, clear it, and then continue toward the objective. If the opponent changes again, we adapt again. We act, they resist, the contact gives us information, we change what we are doing, and we continue.

The route may change several times in only a few moments. The objective does not.

And ultimately, finish

There is a danger when we talk too much about flow, adaptability and continuous movement. It can begin to sound as though continuing indefinitely is somehow the goal. It isn't. If fighting is unavoidable, we want it to end as quickly as possible.

So the full idea is not simply adapt and continue. It is adapt so that you can continue toward the finish. Becoming more adaptable makes us harder to stop, and becoming harder to stop matters because every unnecessary reset gives the opponent more time and another opportunity to attack, recover or change the situation.

The purpose of adaptability is therefore very practical: become harder to stop so that you can finish the fight as quickly as possible.

Adaptability during contact

There are many ways to be adaptable in martial arts. You can change strategy before engagement, adjust distance or timing, choose a different attack, change position, or decide that engagement should be avoided altogether. All of these forms of adaptability are important.

Functional Wing Chun also places considerable emphasis on something else: adapting after contact has already been established. We initiate, the opponent resists, and that resistance creates contact. The contact gives us information, and we use that information to adjust what we are doing while trying to preserve the initiative and continue toward the objective.

This is one reason contact training such as Chi Sao plays such an important role in Wing Chun. Contact is not something we maintain simply for the sake of staying connected. It allows us to feel change. It tells us when the route is no longer clear, and it gives us information that can help us find another one.

The goal stays. The route changes.

Perhaps this is where the image of being “like water” becomes particularly useful. Water does not insist on travelling through an obstacle exactly as it originally approached it. It changes according to what it encounters, but that does not mean becoming directionless.

Functional Wing Chun works in much the same way. The goal stays. The route changes. We initiate toward an objective, encounter resistance, use the contact to gather information, adapt, continue, and, when possible, finish.

WORKS → BLOCKED / COUNTERED → ADAPT → WORKS → CONTINUE → FINISH

A technique is where the exercise begins. Learning how to keep going when the opponent tries to stop it is where adaptability begins.

From Wing Chun to Jeet Kune Do: Bruce Lee's Martial Journey and What It Means for Us

Bruce Lee is arguably the most famous martial artist who ever lived. But before the cinema legend, before Jeet Kune Do, before the philosophy — there was a teenager in Hong Kong learning Wing Chun. Understanding that lineage helps us appreciate both arts more deeply, and raises questions every Wing Chun practitioner should sit with.

How It Began: Ip Man and a Young Bruce Lee

Bruce Lee began training Wing Chun around 1954 under the legendary Grandmaster Ip Man in Hong Kong. He was approximately 13 years old. By most accounts he was an enthusiastic and gifted student — but also a restless one. He trained seriously for several years before emigrating to the United States in 1959.

It's worth pausing on that timeline: Bruce Lee studied Wing Chun for roughly four to five years. He never completed the full system. He did not learn the third form (Biu Tze), and his exposure to the wooden dummy form (Muk Yan Jong) was limited. This is not a criticism — it is simply a fact that matters enormously when we try to understand what came next.

His primary teacher within the school was actually senior student Wong Shun Leung, who is often credited with being the more hands-on instructor during this period. The direct lineage is: Ip Man → Wong Shun Leung → Bruce Lee.

What Bruce Lee Took With Him

Despite the incomplete training, Wing Chun left a deep imprint on Bruce Lee's thinking and movement. Several of the concepts that became central to JKD are, at their root, Wing Chun concepts:

• Centreline theory — controlling and attacking along the centreline of the opponent's body is a foundational Wing Chun principle that Bruce Lee carried directly into JKD.
• Economy of motion — Wing Chun's insistence on the shortest, most direct path between two points became one of JKD's defining tenets.
• Simultaneous defence and attack (Lin Sil Die Dar) — the idea that blocking and striking are not separate events is pure Wing Chun, and it runs through JKD.
• Chi Sao (Sticky Hands) — Bruce Lee continued to practise and teach a version of Chi Sao throughout his life. It informed his sensitivity training and his understanding of trapping range.
• The concept of Wu Wei — acting without unnecessary force or resistance, flowing with the opponent's energy rather than opposing it.

These weren't influences he left behind. They were the foundation he built upon.

Why He Kept Looking

So if Wing Chun gave him so much, why did Bruce Lee keep searching?

This is the question Wing Chun practitioners sometimes feel defensive about, but it deserves an honest answer — and that means resisting the easy defences. Let's look at the more likely reasons.

1. Four years may not have been enough to use Wing Chun against non-Wing Chun fighters.

There is a real difference between learning a system and being able to apply it under pressure against opponents who don't move the way the system expects. Wing Chun's trapping range, its centreline punching, its sensitivity training — these work beautifully when both practitioners are operating within a similar framework. Against a trained Western boxer who is moving laterally, changing rhythm and keeping distance, a four-year Wing Chun student may simply not have had the depth of experience to bridge that gap. It's not that the principles couldn't work — it's that applying them against an unfamiliar opponent requires a level of ingraining that takes considerably longer than four years.

2. He may have been taught techniques rather than the framework behind them.

This is perhaps the most important point, and one that speaks directly to how Wing Chun is often transmitted. If a student learns what to do — the forms, the sequences, the responses — without deeply understanding why, they have a collection of tools without a method for selecting them. The underlying framework of Wing Chun — economy of motion, simultaneous attack and defence, structure over strength — is what makes the techniques coherent. Without that framework, a student encountering a boxer doesn't reach into Wing Chun principles and adapt; they try to find the right Wing Chun technique, fail, and conclude the system doesn't work. It's a teaching problem as much as a learning one, and it's still common today.

3. He was young, curious and genuinely excited by other arts.

We should be careful not to read Bruce Lee's exploration purely as dissatisfaction with Wing Chun. He was in his late teens and early twenties, newly arrived in America, encountering boxing gyms, fencers, judoka and wrestlers for the first time. That kind of cross-training curiosity is healthy and natural. It doesn't require Wing Chun to have failed him — it just requires him to have been a young martial artist with an open and hungry mind. Many of us have gone through similar phases. Not all of them are a verdict on where we started.

4. Bigger movements work better on film.

This reason is rarely discussed seriously, but it deserves to be. By the time Bruce Lee was developing his screen persona in the late 1960s and early 1970s, he was also making practical decisions about what reads on camera. Wing Chun is compact, efficient and — to an untrained eye — can look like very little is happening. The chain punch, for all its effectiveness, does not photograph dramatically. Longer, more extended strikes, visible chambering, dynamic kicks — these communicate power and speed to an audience in a way that close-range structure-based fighting simply does not. JKD's more expansive movement vocabulary was, at least in part, shaped by the demands of the medium Bruce Lee was working in. That's not a criticism of JKD — it's an honest acknowledgement that his art and his career were intertwined.

Jeet Kune Do: Wing Chun's Offspring?

JKD is often described as a synthesis of many arts — Wing Chun, Western boxing, fencing, wrestling, Muay Thai, and more. That is accurate, but the architecture beneath it is largely Wing Chun.

The Jun Fan period (Bruce Lee's earlier, more structured approach before JKD became a concept) was essentially a modified Wing Chun. The stances, the trapping sequences, the centreline punching — all recognisably Wing Chun in origin. Even as JKD evolved into something more fluid and individualised, the Wing Chun skeleton remained.

Bruce Lee himself said: "I have not invented a new style, composite or modification. I have done nothing special. I am just expressing my true self." JKD, in many ways, was Wing Chun asking itself hard questions until it became something new.

What This Means for Wing Chun Practitioners

Bruce Lee's journey raises a question that every serious Wing Chun practitioner should consider carefully: when you encounter a gap, what is the right response?

One answer is to do what Bruce Lee did — borrow. Bring in boxing footwork for the boxer, wrestling for the grappler, Muay Thai for the kicker. It sounds pragmatic, and in some ways it is. But there is a real cost. Every technique you import from another system comes with its own mechanical logic, its own movement patterns, its own assumptions about how the body should be positioned and how force should be generated. Those assumptions often conflict with Wing Chun's.

You end up with a larger toolkit, but a less coherent one — and crucially, you end up fighting in ways your opponent may well be more familiar with than you are.

There is another answer, and I believe it is the better one: instead of expanding the system to meet every opponent, learn to understand every opponent well enough to bring them into the system. Study the boxer's strengths — the rhythm, the head movement, the rear hand — and just as carefully study the weaknesses that same style creates. Then ask not "which techniques should I add?" but "how do I make this a Wing Chun fight?" How do I close the distance, control the centreline, and get to a range where my training is an advantage and his is not?

A simple system, deeply understood and well applied, beats a complicated one. It is faster to learn, easier to access under pressure, and far more reliable when the adrenaline is up. The goal of good Wing Chun teaching is not to give students an answer for every situation — it is to teach them how to turn every situation into a familiar one.

This, I think, is where the real lesson of Bruce Lee's journey lies — not in the arts he added, but in the gap his training left. The gaps he perceived were not a fault in Wing Chun as a system. They were a fault in how it was being taught. He was given techniques without the framework for applying them. He was not taught how to make Wing Chun work against a boxer; he was taught Wing Chun, largely against other Wing Chun practitioners, and left to figure out the rest.

That is a teaching failure, and it is one our community should take seriously.

As for Bruce Lee himself — I think he was on a genuine and admirable path of inquiry. He asked hard questions, and he pursued the answers with extraordinary dedication. But paths of inquiry don't always end where they begin. Had he lived longer, I believe he may well have arrived back at something close to where he started — not the Wing Chun of his teenage years, but a mature, principled understanding that the framework he first encountered, taught with real depth, already contained the answers he spent his life looking for.

When the Challenge Is Real: Understanding the Honest Skeptic

I get challenged to spar fairly regularly. Sometimes it comes from a place of genuine curiosity — someone who has heard claims about Wing Chun, or martial arts in general, and wants to know if any of it holds up. That's a legitimate question, and it deserves a serious answer.

But the way the challenge gets framed is almost always wrong — and that's worth unpacking.

What the Honest Skeptic Is Really Asking

When someone genuinely curious challenges you to spar, what they're actually asking is: does this work? That's a fair question. Martial arts has a long history of inflated claims, mystical explanations, and techniques that collapse the moment they meet real resistance. Healthy skepticism is not just reasonable — it's necessary.

The problem is that sparring is a poor tool for answering that question. It tests one variable on one day between two specific people. It tells you something about the individuals involved, but almost nothing about the system being evaluated.

A driving instructor challenged to a race isn't being asked whether their students become good drivers. They're being asked whether they personally can drive fast today. Those are completely different questions.

The Right Way to Evaluate a System

If you're genuinely curious about whether a martial art works, the answer isn't in the teacher — it's in the students. Specifically:

• Do students at different levels show clear, consistent progress?
• Does the system produce results across different body types, ages, and athletic backgrounds?
• Can the principles be taught and transferred, or does everything depend on one person?
• Are longer-term students still developing, or have they plateaued?

These questions reveal far more than any sparring match. They tell you whether the system is a genuine methodology or just one talented individual surrounded by students who never quite get there.

What I Tell the Honest Skeptic

I don't dismiss the question. The skepticism behind it is healthy and I'd rather engage with it seriously than defend myself against it.

But I do try to redirect it. Don't watch me — watch my students. Ask them how they've developed. Look at whether the teaching is consistent and principled. Ask me what the system doesn't cover, and listen to whether I answer honestly.

That's the conversation worth having. And a genuinely curious person, once they understand that framing, is usually willing to have it.

When the Challenge Is Not What It Seems: The Territorial Challenger

Not every sparring challenge comes from genuine curiosity. Some of them come from somewhere else entirely — and it's worth being able to tell the difference.

What This Challenge Is Really About

The territorial challenger isn't asking a question. They've already decided. Their system is better, they want to prove it, and the sparring challenge is the vehicle for doing that. There's no outcome that genuinely interests them other than winning — or watching you lose.

This kind of challenge has very little to do with martial arts as a practice. It's a dominance ritual dressed up in the language of evaluation. The vocabulary sounds the same — let's test it, let's see if it works — but the intention is completely different.

How to Tell the Difference

Genuine curiosity looks different from territorial posturing, once you know what to look for.

A genuinely curious person observes before they challenge. They watch the students. They ask questions about methodology. They want to understand the principles before testing them. The challenge, if it comes at all, comes at the end of a real inquiry.

A territorial challenger skips all of that. There are no questions about how the system works or what it's designed for. There's no interest in the students or the teaching. There's just the challenge — immediate, blunt, and strangely urgent. The shortcut reveals the intention.

Why Engaging on Their Terms Is a Trap

Here's the uncomfortable truth: you cannot win this kind of challenge. Not really.

If you lose, their point is proven. If you win, it was a bad day, you got lucky, they weren't trying, your system only works against people who don't know how to fight properly. The goalposts move because winning was never actually the point. The point was the challenge itself — the assertion of hierarchy.

Accepting the challenge on those terms means agreeing that this is the right way to evaluate what you do. Even if you win the fight, you've lost the argument. You've validated the measuring stick.

The Better Response

Name what's happening. Not aggressively, not defensively — just clearly.

This feels less like curiosity about what I teach and more like a competition. I'm not interested in competing. If you want to understand what I do and why, I'm happy to have that conversation.

Some people will respond to that. A few won't, and that tells you everything you need to know. Someone genuinely interested in martial arts as a practice — even a skeptical, combative one — can usually engage with an honest reframe. Someone who is purely territorial will have no use for it.

What It Really Reveals

The need to prove one system definitively better than another almost always comes from somewhere personal. An identity too tightly wound around a style. A teacher who needs their students to believe there is nothing worth learning elsewhere. A practitioner whose confidence depends on a hierarchy that puts them at the top.

That's a human response and it deserves some understanding. But it's not a conversation about martial arts. It's a conversation about ego — and that's not one you're obligated to participate in.

The honest skeptic and the territorial challenger can look identical from the outside. The difference is in what they're actually asking — and whether there's a real question underneath the challenge at all.

Learning to tell the difference is its own kind of skill.

What Makes a Martial Art Functional?

Not all martial arts are created equal — and not all teaching within the same art is either. The word "functional" gets used a lot, but it's rarely defined. Here's what I think it actually means, and why it matters.

A Technique Is Not a System

Most martial arts teaching, if you look at it honestly, is a catalogue. Here is a strike. Here is a block. Here is a form containing both. Repeat until memorized.

That's not a system. That's a library without an index.

A functional system doesn't just teach you what to do — it teaches you when to do it, why it works, and crucially, when not to use it. That connective tissue between techniques is where real understanding lives. Without it, students accumulate tools they don't know how to pick up under pressure.

Every Functional System Starts With a Clear Goal

Before anything else, a functional martial art should be able to answer one question clearly: what problem are we solving?

That sounds simple. Most systems can't answer it.

A system designed for sport competition has a different goal than one designed for self-defense. One built around physical development has different priorities than one built for close-range street encounters. None of those goals is wrong — but they produce different choices in what to teach, how to train, and what success looks like.

When a system doesn't define its goal, students end up training hard toward an unknown destination. They get good at the training without knowing what the training is for.

The Honest Conversation About Limits

Every system has a domain where it excels — and edges where it breaks down. A functional teacher teaches both.

This is where a lot of martial arts instruction fails its students. The techniques get taught. The success cases get demonstrated. But the honest boundaries rarely get discussed. What situations is this designed for? What does it not cover? Where should a student look to supplement their training?

That kind of intellectual honesty is rare. But it's exactly what separates a methodology from a belief system. Students who understand the limits of their art can make intelligent decisions under pressure. Students who were never told the limits get surprised at the worst possible moments.

Why I Call It Functional Wing Chun

Wing Chun has a clear original logic. It was built around a specific problem — close range, dealing with a larger or stronger opponent, using structure and economy of movement rather than athleticism. That's a well-defined goal, and when you understand it, the techniques start to make sense as answers to specific questions rather than just movements to memorize.

But a lot of Wing Chun teaching has drifted from that logic. Techniques get passed down without the reasoning behind them. Students spend years drilling responses to situations without ever being taught to read the situation in the first place.

That's why I use the term functional. It's not a criticism of Wing Chun as an art — it's a commitment to teaching it the way it was meant to be understood. Every technique comes with context. Every drill has a clear purpose. And the limits of what Wing Chun covers — and doesn't cover — are part of the curriculum, not an afterthought.

What to Look For in Any System

Whether you're evaluating Wing Chun or any other art, the same questions apply:

• Does the system have a clearly defined goal — and does the teaching reflect it?
• Are techniques taught with context, not just execution?
• Does the teacher honestly address the limits of what the system covers?
• Can students explain why they're doing what they're doing, not just how?

A yes to those questions doesn't guarantee a great art. But a no to any of them should give you pause — no matter how impressive the techniques look in demonstration.

The functionality of a martial art isn't in its age, its lineage, or how many techniques it contains. It's in whether it gives students a coherent, honest framework for solving a clearly defined problem.

Everything else is just movement.
