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.

詠春拳からジークンドーへ：ブルース・リーの武道の旅と、私たちへの意味

ブルース・リーは、おそらく史上最も有名な武道家だろう。しかしスクリーンの伝説になる前、ジークンドーを生み出す前、哲学者として知られる前――香港で詠春拳を学ぶ一人の少年がいた。その系譜を理解することで、両方の武道をより深く味わうことができ、すべての詠春拳修行者が真剣に向き合うべき問いが浮かび上がってくる。

はじまり：葉問と若きブルース・リー

ブルース・リーは1954年頃、香港の伝説的な宗師・葉問のもとで詠春拳の修行を始めた。当時、彼は約13歳だった。多くの証言によれば、熱心で才能ある生徒だったが、同時に落ち着きのない性格でもあった。数年間まじめに稽古を続けた後、1959年にアメリカへと渡った。

この期間を改めて考えてみたい。ブルース・リーが詠春拳を修行したのは、おおよそ4〜5年である。彼はシステム全体を習得しなかった。第三套路（鏢指）は学ばず、木人椿（ムクヤンジョン）への接触も限られていた。これは批判ではなく、その後に何が起きたかを理解するうえで非常に重要な事実だ。

道場において彼の主な指導者は、実際には上級生の黄淳梁（ワン・シュンリョン）だった。この時期、より実践的な指導を担ったのは黄淳梁だったとされている。直接の系譜は、葉問 → 黄淳梁 → ブルース・リーとなる。

ブルース・リーが持ち去ったもの

修行が途中であったにもかかわらず、詠春拳はブルース・リーの思考と動きに深く刻み込まれた。ジークンドーの核心となったいくつかの概念は、その根を辿れば詠春拳に行き着く。

• センターライン理論 ― 相手の中心線を制し、攻撃するという詠春拳の根本原理を、ブルース・リーはそのままジークンドーに持ち込んだ。
• 動作の経済性 ― 二点間の最短・最直線の経路を求める詠春拳の姿勢は、ジークンドーの根幹をなす信条となった。
• 攻防一体（連消帶打） ― ブロックと打撃は別々の動作ではないという考え方は純粋に詠春拳のものであり、ジークンドー全体に貫かれている。
• チーサオ（黐手） ― ブルース・リーは生涯にわたってチーサオを練習し、指導し続けた。それは彼の感覚トレーニングとトラッピングレンジの理解に深く影響した。
• 無為の概念 ― 不必要な力や抵抗を排し、相手のエネルギーに流れるように応じるという考え方。

これらは彼が置き去りにした影響ではない。それは彼が上に積み上げた土台だった。

なぜ探し続けたのか

詠春拳がこれほど多くを与えてくれたのなら、なぜブルース・リーは探求を続けたのか？

詠春拳の修行者がときに防衛的になりがちな問いだが、誠実な答えが必要だ――それは安易な弁護に抵抗することを意味する。より可能性の高い理由を見ていこう。

1. 4年間の修行では、詠春拳以外の相手に通用するには足りなかったかもしれない。 システムを学ぶことと、そのシステムが想定しない動きをする相手に対して、プレッシャーの下でそれを運用できることの間には、大きな違いがある。詠春拳のトラッピングレンジ、センターライン打撃、感覚トレーニング――これらは両者が同じような枠組みの中で動いているときには美しく機能する。しかし横に動き、リズムを変え、距離を保つ熟練したボクサーに対しては、4年間の詠春拳修行者にはそのギャップを埋めるだけの経験の深さが足りなかっただけかもしれない。原理が機能しないのではなく、慣れない相手に対してそれを適用するには、4年をはるかに超える時間をかけて身に染み込ませることが必要だということだ。

2. 枠組みではなく、技術を教えられていたかもしれない。 これはおそらく最も重要な点であり、詠春拳がどのように伝えられるかという問題に直接関わっている。生徒が「何をするか」――型、連続技、対応――だけを学び、「なぜそうするか」を深く理解しないとき、彼らは選択する方法を持たない道具の寄せ集めを手にしたことになる。詠春拳の根底にある枠組み――動作の経済性、攻防一体、力ではなく構造――こそが技術に一貫性を与えるものだ。その枠組みなしには、ボクサーと対峙した生徒は詠春拳の原理で適応しようとするのではなく、正しい詠春拳の技術を探し、失敗し、システムが機能しないと結論付けてしまう。これは学習の問題であると同時に指導の問題であり、今日でも依然よく見られることだ。

3. 彼は若く、好奇心旺盛で、他の武道に純粋に興奮していた。 ブルース・リーの探求を、詠春拳への不満だけで読み解くことには慎重であるべきだ。彼は10代後半から20代前半、アメリカに渡ったばかりで、初めてボクシングジム、フェンシング、柔道家、レスラーと出会っていた。そのような異種格闘技への好奇心は健全で自然なことだ。詠春拳が彼を失望させた必要はなく、ただ彼が開かれた貪欲な心を持つ若い武道家だったというだけでよい。同じような段階を経た人は多い。その全てが、出発点への評決を意味するわけではない。

4. 大きな動きは映画映えする。 この理由はあまり真剣に論じられることがないが、それに値する。1960年代後半から1970年代初頭にかけてスクリーン上の人格を作り上げていた頃、ブルース・リーはカメラに映えるものについて実際的な判断もしていた。詠春拳はコンパクトで効率的であり――素人目には、ほとんど何も起きていないように見えることがある。連続突きはどれほど効果的であっても、劇的には映らない。より伸びやかな打撃、わかりやすい引き手、ダイナミックな蹴り――これらは、近距離での構造的な戦い方にはできない形で、力とスピードを観客に伝える。ジークンドーのより広がりのある動きの語彙は、少なくとも部分的には、ブルース・リーが活動したメディアの要求によって形成されたものだ。これはジークンドーへの批判ではなく、彼の武道とキャリアが不可分に絡み合っていたという誠実な認識だ。

ジークンドー：詠春拳の末裔か？

ジークンドーはよく、詠春拳、西洋ボクシング、フェンシング、レスリング、ムエタイなど多くの武道の融合として語られる。それは正確だが、その下に横たわる構造は大部分が詠春拳だ。

ジュンファン期（ジークンドーという概念が生まれる前の、よりシステム的だった時期）は本質的に改良された詠春拳だった。構え、トラッピングの連続技、センターラインへの打撃――すべてが詠春拳の出自を持つものとして見て取れる。ジークンドーがより流動的で個人的なものへと進化しても、詠春拳の骨格は残り続けた。

ブルース・リー自身はこう語っている。「私は新しいスタイルを発明したわけでも、合成したわけでも、修正したわけでもない。特別なことは何もしていない。ただ自分自身を表現しているだけだ。」 ジークンドーはある意味で、詠春拳が自らに難しい問いを投げかけ続けた末に、何か新しいものへと変容したものだ。

詠春拳修行者にとっての意味

ブルース・リーの旅は、すべての真剣な詠春拳修行者が丁寧に考えるべき問いを提起している。ギャップに直面したとき、正しい答えは何か？

一つの答えは、ブルース・リーと同じことをすることだ――借りること。ボクサーにはボクシングのフットワークを、グラップラーにはレスリングを、キッカーにはムエタイを取り入れる。それは実際的に聞こえるし、ある意味ではそうだ。しかし確かなコストが伴う。他のシステムから輸入した技術は一つひとつ、独自の力学的ロジック、独自の動きのパターン、身体の位置づけや力の生成についての独自の前提を持っている。それらの前提はしばしば詠春拳と矛盾する。結果としてより大きな道具箱を持つが、一貫性は低くなる――そして決定的なことに、相手の方が自分よりもよく慣れているやり方で戦うことになってしまう。

もう一つの答えがある。そして私はそちらの方が優れていると信じている。すべての相手に合わせてシステムを拡張するのではなく、すべての相手を十分に理解して、その相手をシステムの中に引き込むことを学ぶことだ。ボクサーの強みを研究する――リズム、頭の動き、後ろ手――そして同じように注意深く、そのスタイルが生み出す弱点を研究する。そして「どの技術を加えるべきか？」ではなく、「どうすればこれを詠春拳の戦いにできるか？」と問う。どうやって間合いを詰め、センターラインを制し、自分のトレーニングが有利に働き、相手のトレーニングが機能しない距離に持ち込むか？

深く理解され、うまく適用されたシンプルなシステムは、複雑なシステムに勝る。習得が早く、プレッシャー下でも使いやすく、アドレナリンが上がったときにはるかに信頼できる。優れた詠春拳指導の目標は、あらゆる状況への答えを生徒に与えることではない――あらゆる状況を、自分が慣れ親しんだ状況に変える方法を教えることだ。

ここにこそ、ブルース・リーの旅の本当の教訓があると私は思う――彼が加えた武道ではなく、修行が残したギャップの中に。彼が感じたギャップは、詠春拳というシステムの欠陥ではなかった。それは、システムがどのように教えられていたかという欠陥だった。彼は枠組みなしに技術を与えられた。ボクサーに対して詠春拳を機能させる方法を教わらず、主に他の詠春拳修行者を相手に詠春拳を学び、残りは自分で解決するように任された。

それは指導の失敗であり、私たちのコミュニティが真剣に受け止めるべきものだ。

ブルース・リー自身については――私は彼が真摯で称賛すべき探求の道にいたと思う。彼は難しい問いを立て、並外れた献身をもってその答えを追い求めた。しかし探求の道は、必ずしも始まった場所で終わるわけではない。もし彼が長生きしていたなら、出発点に近いところへと辿り着いていたかもしれない――若い頃の詠春拳ではなく、最初に出会ったその枠組みが、深く教えられることで、生涯かけて探し求めた答えをすでに内包していたという成熟した理解へと。
