Stop the Injury Cycle: Overuse vs Training Spikes in Muay Thai 

It’s Not Age or Bad Luck — It’s Load Mismatch

In Muay Thai, especially as you get older, there’s always something. “How do I push without breaking down?” I hear this all the time from fighters.

You want to train more, not less. But, whenever you ramp things up, an injury flares up.

It forms an injury cycle:

Train hard… pain builds… modify training… pain settles… ramp back up… repeat.

You’re not rehabbing, you’re surviving between flare-ups. And you begin to doubt your body’s ability to train effectively.

You feel, “I don’t feel tired, but things keep flaring up”, or “One set back and I lose everything.”

It’s not that Muay Thai is too hard, or that you’re too old; it’s that your body hasn’t adapted to the workload that you’re asking of it. Your training is mismanaged.

Most fighters feel a niggle and either push through, or rest completely. Both extremes accelerate the injury cycle, sharpen its peaks and valleys, and increase the chance of future issues.

It’s not bad luck. It’s a mismatch between your training workload and your body’s capacity to tolerate it. Your training structure is off.

It’s not one bad session. It’s lots of little mismatches, repeated over time.

So let’s look at the two key mismatches.

First we have overuse

These injuries usually gradually build rather than happen in one dramatic moment.

You’ll only sustain repeated work if it’s within your body’s capacity. The more intense, the less you can tolerate. The fewer “days off”, the less your body copes.

I found this on a hot, humid evening in 2010 when I threw a switch-kick in front of twenty heavily breathing fighters I was coaching.

The gym smelled of Thai oil, Prodigy’s “Omen” played in the background, and Jack—my tall, already-sweating heavyweight stooge—stood ready to receive.

As I stabbed the ball of my left foot into the mat and launched the kick, there was a sharp, hot pain above my heel.

But I kept my poker face, landed the technique, and continued coaching: “Land the kick, and go straight into balanced footwork as you angle off.”

Inside, I was thinking: that Achilles is knackered.

What I didn’t know yet was that all those barefoot hours teaching and training had frayed my body’s capacity to cope—and I’d been running on borrowed time.

This is overuse: intensity + frequency minus adequate recovery.

My ropes were fraying long before that kick, and that moment just made me feel it.

Think gradually increasing pain in the Achilles, calves, shoulders, elbows, wrists, hips, groin, knees, lower-back, and shin splints.

These are the result of too much of the same stress, too often, without enough adaptation to cope.

Second we have training spikes

A sudden increase in intensity, frequency, duration, or novelty that exceeds what you’re currently prepared for.

This triggers sudden injuries, sudden flare-ups from background overload, and early-stage overuse injuries appearing quickly.

Think shin splints suddenly appearing after upping your roadwork, shoulder pain after extra pads, knee pain after adding jumps, groin pull after doubling down on high kicks, Achilles flare up after upping your skipping rounds.

A fighter can carry hidden fatigue for weeks, then one spike is the final straw.

And it’s worth mentioning that some injuries are a mix of both overuse and training spikes. For example, shoulder pain may start as overuse, then suddenly flare up in sparring.

The Hidden Trap: Everything vs Neglect

And our training isn’t simple. Muay Thai demands many qualities (mobility, balance, skill, strength, power, speed, and endurance). It’s what makes it so fascinating and exciting. But with so many plates to spin, many fighters either try to train everything, all of the time, or flip between one thing and another.

It’s “everything” vs “neglect”.

FOMO-driven fatigue without adaptation vs dropping the ball on strength, mobility, or resilience… which increases vulnerability.

Try to train everything all the time, and you accumulate overuse. Flip between priorities suddenly, and you create training spikes.

Two Muay Thai Mistakes That Worsen Both

In Muay Thai, there are two key considerations that feed these two mismatches…

First, fight dates can emphasise the training spike mistake. “Cramming” for an upcoming fight can see your training workload rapidly increase, exceeding what your body can tolerate.

Secondly, “sport specific” strength and conditioning heaps further stress on the same movements used in Muay Thai. Fighters that think all their strength training should look Muay Thai are making that mistake.

Solutions

Just being aware of all this, you’re already better armed against overuse and training spikes. You’re going to pay more attention. You’re going to notice. But taking action and structuring your training more effectively, is where it counts.

First, match your training workload to your capacity to handle it.

This is the Big Picture. I recommend repeatedly moving through a 4-stage training cycle. Supplemental S&C shifts emphasis from more general training (that reduces stress on sport specific movements), to incrementally more sport-specific training in each stage. This both peaks performance and protects against overuse.

In each stage in the cycle, some qualities are maintained with a low dose, while focusing effort on progressing others. That way, you avoid training spikes, all your training qualities stay ready, and you can take a fight any time. I’ll link to a video breaking down this cycle at the end.

Now, your Muay Thai builds the skill and a lot of the conditioning. Your strength work should build the capacity that supports it, not duplicate it.

Second, build specific, localised capacity in different body regions.

To avoid shin splints, build calf loading capacity.

For the elbows and wrists, forearm strength.

For the shoulders, shoulder blade (scapular) control.

And generally, balance exercise workload in all 8 major patterns to ensure robust strength around the joints: lower body squat and hinge, upper body pushes and pulls (vertical and horizontal), and core extension and rotation.

Third, structure training intensity.

Not every session has to be hard. For example, your week could contain 2-3 hard sessions, 2-3 technical/light sessions, and 2 strength sessions.

Every week doesn’t need to be all out. I like fighters to progressively stack 4-week blocks with a low week, medium week, high week, and deload week. It sets them up for continuous long-term progress.

Muay Thai Timebombs

Before we move on, two Muay Thai specific timebombs that directly cause training spikes and overuse…

First, pad holding.

Consider pad holding part of your training workload. It can result in shoulder and elbow pain when holding for heavy hitters.

To better tolerate pad holding, consider:

Better pad positioning—holding tighter to your body reduces the leverage on joints. And position the pads so that strikes don’t land toward the top of the pad. That again increases the stress on your joints. The middle of the forearm, and the elbow region can take far more force. And if you can, use a belly shield to take more of the force.

Use a well-timed bracing strategy. Pulse against the strike, catching it on the pads. Avoid passively absorbing the force.

And generally, manage your pad holding workload, especially against heavy hitters.

Second, training in Thailand.

Progressively ramp up training before heading out to Thailand. Steadily build your running volume and pad or bag work rounds. If you spike your training load without preparation, you’re asking for problems.

And a point for those over 35. Remember, it’s not that your body can’t handle hard training. It just needs more preparation and smarter structure.

Pain?

And finally, let’s talk a little about pain.

If you’re already having a flare-up… pain doesn’t always mean damage, but it does mean something needs adjusting. Whatever is happening, your body isn’t adapted to handle it yet.

Adjust your training if pain increases during training, lasts more than 24-48 hours, or changes how you move. If pain keeps coming back or isn’t improving, it’s worth getting it assessed by a professional.

And at the very least, audit your current schedule — which of the two structure mismatches are you making? Overuse or training spikes?
