Warrior Fitness Training Systems

08/31/2026

What has 40+ years of martial arts and strength training taught me?

I recently sat down with Craig Simpson on the Radiant Creators Podcast to talk martial arts, internal power, isometrics, qigong, strength training, and one of the ideas at the heart of everything I teach:

Keep getting stronger every day.

We covered a LOT of ground in this one.

If you're a martial artist who wants to stay strong, capable, and powerful for life, check it out:

The Power Is Already There

Most martial artists don't lose power because they get older.

They lose power because they stop training the body that produces power.

Technique isn't enough.

Muscle isn't enough.

Real martial strength comes from structure, tendons, breath, and whole-body connection.

That's exactly why I wrote The Isometric Warrior Training Guide.

Inside, you'll learn the forgotten isometric methods that build:

⚔️ Structural Strength
⚔️ Tendon Power
⚔️ Joint-Friendly Resilience
⚔️ Internal Connection

Train smarter.

Stay dangerous.

What if your martial arts training had a complete operating system for building the body beneath the art?

Most martial artists train hard.

But very few train with a system.

One day it's kettlebells.

The next it's mobility.

Then breathing.

Then stretching.

Then strength work.

Then another seminar.

Then another YouTube video.

Eventually...

Training becomes a collection of disconnected methods.

Not a path.

Over the last forty years, I've studied traditional Japanese martial arts, Chinese internal arts, old-time strength methods, isometric training, Qigong, breathwork, and modern sport performance training.

For years, I thought I was learning different systems.

Eventually, I realized something.

I wasn't.

I was studying different ways of developing the same body.

That realization became The Iron Body System.

Not another style.

Not another workout.

Not another collection of techniques.

A Martial Arts Operating System.

A complete curriculum for building the body beneath the art.

One that organizes:

• Structure

• Breath

• Movement

• Pressure

• Elasticity

• Unified Force

Into one integrated daily practice.

Because techniques don't make great martial artists.

The body expressing those techniques does.

If you've ever felt overwhelmed by endless training methods...

Or wondered how all the pieces fit together...

This is exactly why I built the Iron Body System.

Build the Body Beneath the Art.

Because the techniques won't change.

But YOU will.

*** Question for you...

If you could improve one thing about your martial arts right now, what would it be?

- Structure?
- Power?
- Mobility?
- Breathwork?
- Internal connection?
- Something else?

I'd genuinely love to hear your answer.

For more than 20 years, I’ve been searching for a way to help martial artists continue getting stronger, healthier, and more capable as they get older.

That journey eventually became The Iron Body System.

And now...

I’ve finally put the philosophy behind it into words.

📜 The Iron Body Manifesto

I didn’t write this for everyone.

I wrote it for martial artists who believe the path doesn’t end when they get older.

If you’re committed to building the body beneath the art...

Comment “MANIFESTO” below and I’ll personally send you a complimentary copy.

When you’ve finished reading it, come back and tell me which principle resonated with you the most.

The techniques haven’t changed.

You have.
