Dig Deep But Know Your Edge–Understand The Moving Scale
In Muay Thai, you must dig deep, but do you know when to push your limits, and when to ease off to level up?
Are you the “More!” type… or the “Too Much!” type?
Over the years—training myself and coaching fighters around the world—I’ve spotted a pattern.
We all live on a sliding scale when it comes to challenge.
And that scale moves.
Push the edge regularly, and your capacity rises.
But let it slide for too long? It drops. Fast.
What challenged you six months ago might not touch the sides today.
Or worse—what used to be easy now feels hard again, because you’ve unknowingly slid backward.
You’re always moving on the scale.
The question is: which direction?

Your Built-In Emergency Brake
Here’s something most fighters never think about…
Achieving Muay Thai gains isn’t just about training hard or easy.
It’s about training smart—knowing where your real limits are, when you’re redlining too often, and when you’re just bailing out too soon.
You’ve got a built-in “factor of safety”—a mental emergency brake that kicks in way before you’re in danger.
And depending on your life experiences, you’ve learned to override that internal safety brake in some areas—maybe at work, in family situations, or even in fighting.
But not every area.
Think about how comfortable you feel with each of these:
- Public speaking
- Competing in Muay Thai
- Driving in heavy traffic
Each one has a different challenge threshold for you—based on how much you’ve been exposed to it, and how recently.
Your setpoint for challenge isn’t universal—it’s specific, and constantly shifting.
So here’s the truth bomb:
- If you’ve never hit a true physical/emotional limit, you’re probably not pushing hard enough.
- If you always hit the wall, you’re overshooting.
- And if you don’t know which you are… that’s your first job.
Dig Deep = Train Hard… But Redefine What “Hard” Actually Means
Jerry Rice said,
“Today I will do what others won’t, so tomorrow I can achieve what others can’t.”
Most folks take that to mean go harder, longer, faster.
But what if the real grind… is in mastering the “boring” stuff?
- Footwork
- Mobility
- Stability
- Strength
- Endurance.
The stuff that doesn’t make your Instagram reel—but makes your Muay Thai game bulletproof.
You can’t skip steps.
Too many fighters try to fast-forward to the sexy bits—KO power, flying knees, shredded abs.
But the truth is, those results are built on top of slow, deliberate, foundational work.
Are you willing to be the tortoise, not the hare?
So… Where Are You On the Dig Deep Continuum?
Everything swings like a pendulum.
Do too little? You stall.
Do too much? You break.
Even your strengths can become weaknesses if you don’t keep them in check.
So ask yourself:
- Where do I naturally overdo it?
- What kind of training do I avoid?
- Am I chasing validation or building foundations?
Because the real question isn’t, “Am I working hard?”
It’s “Am I working smart, for where I am right now?”
Be Brutally Honest
If you’re slacking?
This is your wake-up call. Get to work.
If you’re grinding nonstop?
This is your permission to dial it back and build the base you’ve been skipping.
Because this isn’t about going soft.
It’s about going smart.
And that’s how you build a body—and a mindset—that wins in the long game.
