Muay Thai Strength Training: Stop Cancelling Your Own Gains

You’ve been doing the gym workout, leaving every session wrecked, and your power hasn’t improved in months.

Your training is telling your body to build endurance instead of strength, and those two signals cancel each other out.

Have you ever wondered why the hardest workers in the gym are often the ones who never actually get stronger?

Let me show you why.

Traditional Thai fighters throw powerful kicks and dominate the clinch, yet their training doesn’t develop their raw force production.

Their power comes from near-perfect technical efficiency, meaning when you separate a strike into what the muscle generates versus what the technique delivers, traditional training only develops the delivery.

So if the training doesn’t build raw strength, why have most Muay Thai gyms turned resistance training into conditioning?

To answer that, I need to borrow a framework from my engineering background. It’s called the Input-Process-Output model, IPO for short. It’s a three-part foundational systems theory used in engineering, software development, and systems analysis to describe how any process transforms raw elements into intended results. And it applies perfectly to striking power.

Part 1, the input is raw force generation. How much of your genetic power potential you have actually developed through training. Part 2, the process is technical efficiency. How much of that raw power transfers through your technique, through your kinetic chain, into the strike without leaking. Part 3, the output is what reaches the target. The end result. The final power your opponent feels when you land your shot.

Here’s where the classic Soviet research comes in, because it puts hard numbers on exactly how the process stage works.

Researchers broke down where force actually comes from in a punch by measuring the contribution from each body segment. Beginners generate force like this. Only seventeen percent from leg drive, forty-five percent from trunk rotation, and thirty-eight percent from the arm. They’re firing a cannon from a canoe. The foundation isn’t even engaged.

But knockout artists use thirty-nine percent leg drive. More than double what beginners use. Thirty-seven percent trunk rotation. Only twenty-four percent arm extension. They fire from solid ground.

This tells us two critical things. First, technique matters more than effort. The knockout artist isn’t swinging harder. They’re sequencing better. Second, and this surprises most fighters, lower body strength contributes more to punching power than upper body strength does.

When most fighters try to hit harder, they tense up, they skip segments in the kinetic chain, and they focus predominantly on the striking limb. Some even add resistance bands to their punches, which teaches exactly the wrong pattern by training the arm to fire independently instead of riding the chain from the ground. Elite strikers do the opposite. They show a distinct pattern of tense, coast, tense on impact. Initially firing to launch the strike and maximum stiffness at the moment of impact, with a moment of relaxation between the two. That creates what sports scientists call effective mass. Think of it like the difference between hitting with a steel bat and hitting with a foam noodle. Even if they weighed the same, the transfer of energy is completely different.

A strike is an energy transfer system. Generate force from the ground, relax to connect the segments, throw through the target, stiffen on impact. The power comes from the ground up. The limb is just the last link in the chain.

Now here’s why the IPO model matters for understanding the Thai advantage.

The typical Thai fighter has spent years honing the process. Thousands of repetitions, thousands of rounds. Their kinetic chain is dialled in. Their leg drive, trunk rotation, arm extension are sequenced perfectly. Their technical efficiency is through the roof. We’re talking ninety-eight percent of whatever raw input they produce actually makes it into the output. That’s world-class.

But the input, the raw force generation, is only at about fifty percent of what their body is capable of. Because traditional training doesn’t overload the muscles enough, doesn’t use enough load, and doesn’t give enough rest between efforts to trigger the adaptation that builds raw strength and power. They’re racing with a V4 engine when they could be running a V8.

Fifty percent input times ninety-eight percent process efficiency equals forty-nine percent of total genetic potential as output. That’s what you see in the ring. It looks devastating because the efficiency is so high. But almost half the engine is sitting idle.

Now compare that to a Western fighter who also hasn’t trained for raw strength. Same fifty percent input. But their process efficiency is lower, say thirty percent, because they’ve not had the same thousands of hours of repetition. Their output? Fifteen percent. The gap is efficiency. The Western fighter has similar raw potential but loses most of it through poor transfer.

And here’s where this gets interesting for you.

If that same Western fighter develops their raw input, with proper strength and power training (heavy loads, full recovery), they can push the input up to around eighty percent of their genetic potential. And if they also improve their process to say sixty-one percent efficiency, which is achievable with focused work, their output hits forty-nine percent and matches the Thai fighter. You’ve caught them by training the right thing. Volume was never the problem.

The point is this. Traditional Thai training builds the process brilliantly; the kinetic chain, the sequencing, the technical transfer from ground to target. But it does almost nothing for the input. And when most gyms copy that model, and when they turn every resistance session into another conditioning circuit, they’re chasing the process over and over while the input just sits there, waiting. You’re refining a delivery system that has nothing to deliver.

Thai training is brilliant at what it does. But right next to it sits untapped potential.

Last video I showed you how chasing the burn in conditioning shrinks your aerobic engine. How the fatigue from high-intensity work at the wrong time sabotages the adaptation you’re actually chasing. Today it’s the same law in a different domain. This time it’s your strength and power being held back and the culprit is the same. Your training feels hard but signals the wrong adaptation.

—————

So the IPO model shows you that traditional training builds the “process” but barely touches the “input”. The obvious question is what’s actually happening in the gym that creates this gap?

If you walk into most Muay Thai gyms during the strength and conditioning portion of a session you’ll typically see the same thing: kettlebell complexes done for time, medicine ball slams with ten seconds of rest, push-up ladders until failure, circuits that mix everything into one continuous burn. The workout leaves you on the floor, it feels productive, and everyone around you is doing it, so it must be working.

But feeling destroyed isn’t the same as adapting.

The problem is that this kind of training, all those hours each week in Thailand spent not doing Muay Thai (running, skipping, body weight exercises, high-rep low-load resistance work), all produces fatigue without developing raw strength and power. And when Western gyms copy that model, turning resistance training into another conditioning session, they’re duplicating the same limitation.

So what is actually missing? What conditions must be met for your body to get stronger, more powerful, faster?

Well those neuromuscular qualities need two things that normal Muay Thai training doesn’t provide. The first is overload intensity. The movements must be loaded at a high percentage of your maximum force, and you need to be fresh when you do it. We’re not looking for a moderate effort, until it burns, we’re talking close to absolute failure with no reps left in you at all. The second is rest. Your rest intervals between efforts must be far longer than you get in a typical class. Fatigue blunts the neural signal. If you’re tired when you lift, you’re not training strength. You’re training the ability to lift while tired, which is a different quality entirely.

This is where many fighters hit a glass ceiling. They’re working harder than anyone in the gym, first in the door and last to leave, and every session leaves them wrecked. And yet, month after month, their power doesn’t improve. Their clinch strength stays the same and their kicks don’t land heavier.

There’s a principle here that’s so fundamental I need you to remember it. Before you can do strength endurance or power endurance, you must first build strength and power. You can’t endure qualities you don’t have.

Most fighters skip the build phase and go straight to the endure phase. They’re actually practicing being weak for longer.

Let me show you what this looks like with two fighters so you can see the difference.

Fighter A spends four weeks building raw strength with heavy loads and full rest between sets, two sessions a week, nothing fancy. By the end of the block, their maximum deadlift, their pull-up strength, their power output have all climbed. Then they layer on the endurance work like circuits, shorter rest, higher volume. Now they’re expressing that new strength under fatigue. The ceiling has moved up.

Fighter B does the same number of sessions, same total time, but every session is a circuit. Everything mixed together at high effort, and feels destroyed after every session. But four weeks later, their maximum strength has barely moved. They feel fitter, maybe. But they’re not stronger. They‘ve not built anything new to endure. They’re just more efficient at operating near their ceiling.

Fighter B trained harder. Fighter A got stronger. Same hours, same gym, completely different result.

By blindly valuing work ethic over building athletic qualities in the right sequence you’ll inadvertently send your body the wrong signal at the wrong time. Training submaximal output while fatigued builds submaximal output.

The signal for strength and power is high force, long rest, and a fresh nervous system.

If you mix in an endurance signal too, that strength and power signal is cancelled out and all you get is tired.

That’s the diagnosis. The input stage of your power delivery system is underdeveloped because the training that’s supposed to build it is sending the wrong signal. Until you separate the build phase from the endure phase, the cycle repeats and nothing changes.

—————

But theory only gets you so far. Let me show you what this looks like in practice, with a real fighter who lived it.

Johan is a Muay Thai fighter who came to me stuck. Before the program, he was running hard intervals above 90 percent and seeing no improvement. The training felt intense. He was working really hard, but the results were flat and nothing was moving. He was trying to endure a power output he’d not built yet. The high intensity work was draining him without triggering adaptation because the foundation wasn’t there. He was practicing being weak for longer, just like we talked about.

To solve this we stopped adding more and removed work instead. We took out the empty high intensity grind completely and switched to a strategic approach that separated the build phase from the endure phase. We had the same total training time, took longer rests, and used a completely different structure. Rather than doing more work he was doing different work, at the right time, in the right order. He told me, “I now enjoy S&C. And for the first time I look forward to lifting.”

And then there was how he felt in his Muay Thai training, “This last week I felt like I could not get tired during sparring or pads.”

They’re direct quotes from a fighter who was running himself into the ground with hard intervals and getting nowhere. Now he’s in the gym and his tank won’t empty. By shifting emphasis and ensuring his engine had the foundation to deliver, the endurance took care of itself.

Johan isn’t an isolated case. Izzy went through the same process and told me, “I learned that doing less and actually resting is so beneficial.” Resting between strength lifts isn’t laziness, it’s actually what builds strength.

Lenore told me, “I really find it so fascinating, how well and quick this program changes my body while I don’t even feel I have been doing THAT much.” The work didn’t feel extreme or leave her destroyed. And yet the changes came faster than when she was grinding.

These aren’t outliers, they’re what happens when you stop sending conflicting signals. When you build the foundation before you try to endure it, the body responds. Precision matters more than just grinding in the wrong direction.

—————

So we have seen the diagnosis and we have seen the proof. Now let me explain why this happens. Because once you understand the mechanism, you stop guessing and you start making good decisions.

Let’s take a simple example, like chin-ups. Say your current maximum is five reps. Three chin-ups leaves effort in the tank for you. It’s sixty percent of your max number of reps and you feel it. Now imagine you spend a block building raw pulling strength and your max climbs to fifteen reps. Those same three chin-ups are now twenty percent of your capacity. They feel like nothing, you could smash them out all day. The movement hasn’t changed, nor has the weight. But your ceiling moved up, so the same demand that used to challenge you is now easy.

This is the principle. Strength appears as endurance. Build the raw quality first and submaximal output becomes effortless.

I have testing data from a Heavy Hitters client, Aiden, that proves this with real numbers. Aiden scores well on upper body strength. But his anaerobic fatigue and aerobic power numbers are below what you would expect from a pro Muay Thai fighter. So he’s strong, but relatively lacking in conditioning. You’d expect his muscular endurance should be poor too. Yet when we test him on maximum pushups and maximum chin-ups, he performs well. The reason is the principle we just walked through. His max strength ceiling is high enough that submaximal reps stay submaximal for much longer before fatigue sets in. The testing data confirms exactly what the model predicts.

The exact same thing happens in a fight, just with different numbers. When your maximum force output climbs, the submaximal demands of every clinch exchange, every kick, every time you post off your opponent to create distance, drop to a smaller and smaller fraction of what you’re capable of. You don’t get tired because your engine has headroom. It’s the same fight, with the same opponent and the same number of exchanges. The only thing that changed is your ceiling.

When you train for strength or power, you’re sending a neuromuscular signal. A high force output with full recovery between efforts and low fatigue. Your nervous system learns to recruit more motor units, fire them faster, coordinate them better. This is the signal that builds the input stage of your power delivery system.

When you train for endurance, you’re sending a metabolic signal. A sustained output with incomplete recovery and high fatigue. Your body adapts by building capillaries, increasing mitochondrial density, improving buffering capacity. It’s important work, but it’s a different signal.

The problem is these signals conflict. You can’t maximise both at the same time. If you try, the body compromises. The endurance signal blunts the strength signal, and what you get is more endurance work, which you’ve already got covered. You put in the hours, you feel destroyed, and nothing changes. The volume is there but the stimulus isn’t. You can’t adapt to a signal you never received.

Think of it like the gears on a bike. You don’t try to pull away from a standstill on a hill in the highest gear. You’ll stall immediately. Instead, you start low, spin the pedals, build momentum, and squeeze every bit of acceleration out of each gear before you shift up. Skip a gear too early and you lose speed. Try to start in top gear and you go nowhere. The sequence exists because without it you waste effort and can end up going backwards.

This is the domino principle. You can’t endure qualities you don’t have. The foundation momentum must be built before you channel it elsewhere and add to it. If you skip the build phase and go straight to the endure phase, you’re not training harder, you’re training wrong. All that effort is producing fatigue without adaptation. It’s wasted work.

—————

Separation is the key principle here. But principles are useless if you can’t apply them, if you don’t know what to do on Monday morning. So here’s the system. It’s called the Optimal Training Cycle and it’s the filter that makes every decision for you.

The Optimal Training Cycle sequences your training through four phases. First, the Foundation block. This is where you build the aerobic engine, fix any weak links in mobility and stability, and prepare your body to handle the work that’s coming. No shortcuts. Skipping the foundation causes any performance built on top to crumble.

Then a Strength block. This is the build phase for the input stage. You use heavy loads with full rest, low fatigue, and high neural demand. You’re building the ceiling. Every resistance training session is designed to predominantly trigger the strength signal, maximum force production, to get stronger.

Then a Power block. Now we multiply that force by velocity. You take the strength you built and teach your nervous system to express it explosively, using exercises like loaded jumps, kettlebell swings, olympic lifting variants if you want to. The ceiling stays high but now you hit in a fraction of a second.

Then a Peak block. This is where the focus shifts to maximum velocity, the highest speed possible, and true endurance enters the picture. Now that you have something to endure, you layer on the fight-specific conditioning, using the highest intensity intervals and higher volume. The difference is that now you’re enduring qualities you’ve actually built. You’re conditioning strength instead of practicing weakness.

Each phase has its moment, and the key rule is that when you add a training method, you must take something away. Adding means removing. You can’t keep everything from the previous phase and pile more on top. You’ll drown clean training signals in noise, and you won’t recover well. Recovery is when your body builds in response to the training signal. If you don’t give yourself space to improve, you won’t improve. You need to master rotation. Rotate in the work that compounds with the current phase, and rotate out what catabolizes it.

It’s about doing the right thing at the right time and having the discipline to stop doing what no longer serves you, rather than defaulting to trying to do more.

Now let me give you the target. What are you actually training for? The goal is to have the engine to relentlessly out-power your opponent. To push a workrate that drowns them in fatigue when trying to keep up with you.

Any fighter pushing at 100% can only keep it up for a limited time, and needs ever increasing rest periods to recover. The secret to being a relentless fighter is to use your 100% effort sparingly, and apply 80% effort mostly. At 80%, you can just keep going and going, round after round. And when your 80% equals your opponent’s 100%, you destroy them with work rate. They fade, you don’t.

I have a formula for this I call the Relentless Fight Pace. It has three parts. First, you need about 80% of your maximum strength and power. Not a hundred. We want your submaximal output to be higher than your opponent’s max.

Second, you need about 80% of your maximum aerobic power. That’s the engine that sustains output without going into debt.

Third, you need economy of Muay Thai movement. Efficiency. The ability to produce effective strikes without wasting energy on unnecessary motion or effort. Multiply those three together and you get a fighter who doesn’t slow down.

That’s the fix. Separate phases that stack on each other. Build before you endure. Filter everything through the question: does this compound with what I’m trying to do right now, or does it catabolize it? If it doesn’t compound, park it. It’ll have its moment later, not right now.

When it all comes together, this is what it feels like. You’re in the fourth round, your opponent’s hands are dropping and their kicks have lost their snap. They’re surviving, while you’re still sharp and bringing the pace you had from the start of the fight. They look at you between exchanges and don’t understand how you can keep pushing like that. They look for every opportunity to take a break. They “lose” their gumshield, they fake low blows, they look to the referee to buy some time. They assume you must have trained more than them. You look fresh, while they’re fading.

You didn’t rely on luck, or being the fighter who simply does more than every opponent. You sequenced your training, you used the Optimal Training Cycle. You stopped just grinding and started building.

—————

So let me bring this all together. You came into this episode thinking your gym workout was certainly making you stronger. You have been working hard, leaving every session destroyed, and wondering why the results aren’t coming.

Most Muay Thai training builds the process stage of your power delivery system: the efficiency, the technique, the ability to transfer force. But it barely touches the input. The raw strength and power that the process is supposed to deliver never gets built. You’ve been optimizing a delivery system that has nothing to deliver.

The mechanism isn’t complicated. When you mix strength signals and endurance signals in the same session without separation, two things go wrong. Conflicting adaptation cancels the most important signals. Recovery sabotage dilutes them so nothing reaches the dose required for adaptation. Either way, you work, you suffer, and you stay the same.

The fix is the Optimal Training Cycle. Separate the build phase from the endure phase. Foundation comes first, then strength, then power, then peak. Each phase has its moment, and when that moment passes, you shift. Rotate in what compounds. Rotate out what catabolizes. If you add something, you must remove something. Accumulating more and more is a mistake. Be precise, target your training.

When you get this right, the payoff isn’t theoretical. It’s Johan telling you he couldn’t get tired. It’s Aiden’s testing data showing him outperforming on muscular endurance despite lacking conditioning, because his strength ceiling is high enough that submaximal work stays submaximal. It’s Izzy learning that doing less and actually resting is so beneficial. It’s Lenore watching her body change faster than ever without feeling destroyed. These aren’t outliers. They’re the predictable result of sending the right signal at the right time.

The Relentless Fight Pace is the target. Eighty percent of your max strength and power, multiplied by eighty percent of your max aerobic power, multiplied by economy of Muay Thai movement. Build that and you become the fighter who doesn’t slow down. When your eighty percent equals their hundred percent, you drown them in work rate.

Now I didn’t learn this because I was a gifted athlete. I started competing as a fighter at thirty-two. No coach, no corner, trained on mats. By the time I retired I was UK ranked number four, beating fighters half my age. My secret wasn’t talent. It was the physicality. It was getting the sequence right. My S&C was so far ahead that I could just keep going when they couldn’t. I won because my engine kept running when theirs quit. The skill gap was real, but it didn’t matter once they faded. Fatigue makes cowards of us all. — General George S. Patton Jr.

If you’re stuck, if you’re working hard and the results are flat, the answer isn’t more volume. Targeted Effort Beats Grinding Effort. I’ve put together a free Muay Thai Performance Scorecard that helps you diagnose your own limiting factors and gives you specific recommendations to fix them. Link’s in the description.
