Yielding vs. Overcoming Isometrics: The Two Types of Strength for Martial Artists

Yielding vs. Overcoming Isometrics: The Two Types of Strength for Martial Artists

There’s a reason isometric training has quietly become one of the most powerful tools for martial artists, grapplers, and fighters who want to develop real strength without destroying their joints.

But here’s something most people don’t realize:

Not all isometrics are the same.

In fact, there are two fundamentally different types of isometric training, and each one develops a completely different layer of strength.

These are known as:

• Yielding Isometrics
• Overcoming Isometrics

Understanding the difference between these two methods can completely change how you train.

Because when they’re used correctly, they develop the exact qualities that traditional martial artists valued most:

• structural integrity
• tendon strength
• breath control
• whole-body power

Let’s break them down.

Yielding Isometrics

The Foundation of Structural Strength

A yielding isometric is when you hold a position against gravity or load without allowing your posture to collapse.

You are resisting the force and refusing to give up the position.

In other words:

You yield to the load, but you do not break.

Examples include:

• horse stance holds
• planks
• side planks
• push-up holds
• goblet squat holds
• wall sits
• suitcase carries

In martial arts, these positions closely resemble traditional stance training or zhan zhuang standing practice.

They develop something that most modern strength programs ignore – structural endurance.

Instead of building strength through movement, you build strength by learning to maintain alignment under pressure.

And that produces several powerful adaptations.

Yielding Isometrics Build Tendon Strength

When you hold a position for time, the load transfers directly into the connective tissue.

That means you strengthen:

• tendons
• ligaments
• fascia chains

These tissues adapt slowly—but when they do, the strength becomes extremely durable.

This is why old martial artists could train for decades without breaking down.

Yielding Isometrics Train Breath Control

One of the most overlooked benefits of static holds is how they affect breathing.

When you hold tension for time, the nervous system must learn to regulate pressure and breathing simultaneously.

If your breath panics, your structure collapses.

Learning to breathe calmly under load builds the same composure needed for:

• grappling exchanges
• striking under pressure
• resisting takedowns

Yielding Isometrics Improve Posture and Alignment

Static holds teach the body how to:

• stack joints correctly
• distribute tension through the body
• root into the ground

This is the foundation of what many internal martial arts call connected power.

The Limitation of Yielding Isometrics

While yielding isometrics are incredible for building structure and endurance, they have one limitation.

They do not train maximum force production.

In other words:

They make you stable and durable—but not necessarily explosive.

That’s where the second type of isometric training comes in.

Overcoming Isometrics

The Hidden Method for Building Raw Power

An overcoming isometric occurs when you attempt to move an object that cannot move.

Instead of holding a position, you push or pull against an immovable resistance.

Examples include:

• pulling against straps or chains
• pushing against a wall
• rack pulls against safety pins
• belt squat pulls
• towel pulls in horse stance

In these exercises, the goal is to apply maximum force.

The object doesn’t move, but the nervous system behaves as if it should.

This creates an extremely powerful training effect.

Overcoming Isometrics Train Maximum Neural Recruitment

When you attempt to move an immovable object, the nervous system recruits as many muscle fibers as possible.

This dramatically increases strength.

Even though the object never moves, the body learns how to generate maximum contraction.

Overcoming Isometrics Build Explosive Power

These exercises train the ability to produce force quickly.

That makes them incredibly valuable for martial artists who want to improve:

• striking power
• grappling pressure
• pushing strength
• pulling strength

Overcoming Isometrics Strengthen Tendon Elasticity

Short bursts of maximal tension also increase the spring-like behavior of tendons.

This creates the elastic recoil responsible for powerful striking and throwing mechanics.

The Limitation of Overcoming Isometrics

Overcoming isometrics are extremely intense.

If they’re used too frequently or without proper structure, they can:

• fatigue the nervous system
• create excessive tension
• encourage breath holding

This is why the best systems combine them with yielding isometrics.

The Real Secret: Combining Both Methods

The most effective strength systems use both types of isometrics together.

Yielding isometrics build:

• structure
• endurance
• tendon durability
• breath control

Overcoming isometrics build:

• maximum force
• explosive strength
• neural recruitment
• elastic tension

In traditional martial philosophy, this combination represents the balance of:

Yin and Yang.

Yielding training stores potential.

Overcoming training releases it.

Together they build a body that is both stable and powerful.

How I Teach These Methods

Inside my training programs, these two methods are integrated into a progressive system.

Final Thoughts

Many martial artists spend years training technique while neglecting the body that must perform it.

The result is predictable:

Skill increases.

But power becomes inconsistent.

By combining yielding and overcoming isometric training, you develop something different:

A body that can express technique effortlessly.

Stable.

Elastic.

Calm under pressure.

The way martial artists were meant to move.

The Five Pillars of the Iron Body

Posted on March 10, 2026 by Jon

How Martial Artists Build Lifelong Strength, Power, and Durability

There is a quiet truth that most martial artists eventually discover.

Technique alone is not enough.

You can know hundreds of techniques, understand strategy, and have decades of experience… but if the body itself is not developed correctly, that knowledge cannot be fully expressed.

The greatest martial artists throughout history understood something very important:

They didn’t just train techniques.

They trained the body itself.

They forged a body that was:

• elastic
• structurally aligned
• internally powerful
• externally durable
• and capable of integrating all these qualities into real movement

This type of body is what I like to call The Iron Body.

And over the decades, after studying internal martial arts, strength training, Qigong, and traditional conditioning methods, I’ve come to understand that the martial body develops through five essential pillars.

The Five Pillars of the Iron Body

Every powerful martial artist develops five core qualities:

Elasticity
Structure
Pressure
Durability
Integration

When these pillars are trained together, the body becomes both powerful and resilient.

Let’s look at each one.

Pillar One: Elasticity

The Spring of the Body

Muscular strength is useful, but true martial power comes from something deeper.

The body must behave like a bow.

When tendons and connective tissue become elastic, they store energy during movement and release it explosively.

This is why skilled martial artists often appear relaxed yet generate tremendous force.

They are not relying on muscular tension.

They are using elastic power.

Training methods that develop elasticity include:

• Yi Jin Jing tendon training
• structural isometrics
• slow movement exercises
• controlled connective tissue loading

This is exactly the focus of my Iron Silk Method program.

Iron Silk is designed to restore the elastic connective tissue qualities that allow martial power to feel effortless.

When elasticity develops, many practitioners notice:

• strikes feel heavier
• movements become smoother
• the body feels springy instead of stiff

Elasticity is the engine of martial power.

Pillar Two: Structure

The Frame That Carries Force

Power does not come only from the muscles or tendons.

It must travel through the body.

Structure is what allows force to move efficiently through the skeleton into the ground.

When structure is correct:

• the body becomes stable
• pressure flows through the frame
• muscles remain relaxed

When structure collapses, power disappears.

This is why many internal martial arts emphasize standing practice.

Standing training teaches the body to align:

• feet
• hips
• spine
• shoulders
• head

When these elements are stacked correctly, the body becomes capable of carrying tremendous force without strain.

This is the focus of Zhan Zhuang training.

Zhan Zhuang develops:

• posture
• root
• internal connection
• relaxed strength

Over time, standing practice creates a body that feels heavy and stable under pressure.

Pillar Three: Pressure

Breath-Driven Internal Power

Breathing is far more than a relaxation tool.

In traditional martial arts, breath is used to create internal pressure.

This pressure stabilizes the body and fuels movement.

Practices that develop internal pressure include:

• dantien breathing
• whole-body breathing
• compression and expansion drills

When breath and structure work together, something powerful happens.

The body begins to move as one connected unit.

This type of breathing is a key component of both Iron Silk and Martial Qigong training.

Pillar Four: Durability

The Armor of the Body

Elasticity creates power.

Structure directs power.

Breath fuels power.

But the body must also be able to handle power.

That’s where durability comes in.

Durability refers to the strengthening of:

• bones
• tendons
• muscles
• skin
• connective tissue

Historically this was developed through hard Qigong training.

Practices included:

• static posture strength training
• tendon conditioning
• iron body methods
• breath-powered tension

This is exactly what is taught inside my Martial Qigong course.

Martial Qigong develops the external strength and durability that allows martial artists to remain strong and resilient as they age.

Without durability, elasticity becomes fragile.

With durability, the body becomes capable of absorbing and delivering force safely.

Pillar Five: Integration

Turning Training Into Martial Power

The final pillar is integration.

Integration is where everything comes together.

Elasticity, structure, breath, and durability must eventually become one coordinated system.

This is what allows martial artists to move naturally and generate power without thinking.

Integration is developed through:

• slow martial movement
• striking mechanics
• grappling pressure drills
• standing meditation

At this stage, the body begins to express power effortlessly.

Many practitioners describe this as:

• heavy hands
• relaxed strength
• effortless issuing

This is the stage where training becomes true martial skill.

The Foundation of Everything: Daily Practice

All five pillars rest on one essential foundation.

Daily practice.

The martial body is not built through occasional effort.

It is built through consistent, intelligent training over time.

Even short daily practice sessions can create profound changes in the body.

A simple daily structure might include:

Standing practice
Iron Silk tendon training
Breathing exercises
Martial Qigong conditioning

Over weeks and months, these practices gradually transform the body.

This is how martial artists develop strength that lasts decades instead of years.

Bringing It All Together

When the five pillars are trained together, the body begins to change in remarkable ways.

Elastic connective tissue creates explosive power.

Structure carries force efficiently.

Breath generates internal pressure.

Durability protects the body.

Integration turns all of this into martial ability.

This is the essence of The Iron Body Protocol.

And it is exactly what my training programs are designed to develop.

• Iron Silk Method builds elasticity and tendon power
• Martial Qigong develops durability and external strength
• Zhan Zhuang standing practice creates structure and internal connection

Together, they form a complete system for building a powerful, resilient martial body.

Train for the Long Path

Martial arts are not just about fighting.

They are about developing the body and mind over a lifetime.

When you train the five pillars consistently, the goal is simple:

To become stronger, healthier, and more capable every year.

Not weaker.

Not slower.

But better.

That is the path of the Iron Body.

Train with intent.

Which Warrior Fitness Program is Right for You?

Posted on January 25, 2022 by Jon

I get asked this question all the time – Jon, which one of your programs should I start with?

And the answer is, it depends on your goals.

So in this article I’m going to give you a set of general guidelines to help you decide which program is right for you.

Quick disclaimer before we get started: ALL of my programs are designed to increase functional strength, improve mobility/flexibility, and build your health and energy reserves.

Even though my training is forged in the crucible of martial arts, you do NOT need to be a martial artist to reap all the benefits from any of my programs.

So here goes…

If you are a martial artist looking to unlock the methods of internal power which make ANY art powerful and useful then I recommend starting with Integrated Strength, Shadow Strength, or The Power Protocol.

Each one of these looks at the secrets of internal power and strength from a slightly different perspective to guide you into becoming an all around power house in your respective art.

If you are a weekend warrior looking for the edge in your strength and conditioning training, I suggest the WarFit Program or Sledgehammer Domination which are designed to build superior levels of functional strength, burn fat, and increase all around endurance.

If you are looking to build up your energy reserves and recover faster from all your training and life stress, I suggest Evolve Your Breathing or Vital Force. Both these programs will balance out your workouts and help build health, energy, and give you the edge in your recovery.

And lastly, if you are a man in the over 40 crowd, I highly recommend Strong(er) Over 40 and Dad Strength. These programs will guide you to growing stronger as you get older, along with building and keeping your levels of testosterone high!

At any age and in any life circumstance, keep training, keep pushing, keep growing, and always keep challenging your perceived limits!

NEVER Cocktail Your Training… Here’s Why

Posted on November 25, 2020 by Jon

NEVER Cocktail Your Training – Here’s Why…

Cocktail Training is a term coined by world renowned sports training expert, Dr. Tudor Bompa. It refers to mixing various exercise programs together, having arbitrary and even contradicting goals.

The basic idea is this – if you don’t have clearly defined goals and progressions when you train, you will, in effect, get nowhere. As I often say, random exercise selection leads to random results.

Let Me Do the Heavy Lifting for You

Each program in the Warrior Fitness training library is specifically crafted to avoid the cocktail training effect and maximize your strength, conditioning, and skill development goals.

The entire catalog of stand-alone programs can be found HERE

However, if you’d like me to design a 1-month training program specific to your personal needs, goals, and unique situation, I am offering a special discount price on program design for today only.

Allow me to do the “heavy lifting” for you and design the perfect program to meet and exceed your goals. All you have to do is follow it and put in the sweat equity!

What’s included in each monthly program?

Professionally designed fat-burning, functional muscle & strength building, whole body workouts (video details of every exercise and written workout plans)

Create a 2 month program for me <<===

Create a 3 month program for me <<===

NO Excuses!

With gyms shutting down again and the holidays coming up, most people rationalize (i.e. – make excuses) to themselves that it’s ok to be weak and lazy and “just take some time off from training”… You are NOT most people. Warriors are a rare breed who do not find excuses but find a way instead.

Do not slack off in your training. Now it is more important than ever to stay strong, healthy, and fit for whatever life throws at you.

Random Training = Random Results

Posted on June 12, 2020 by Jon

One of the biggest problems rampant among many types of fitness programs is that random training yields random results.

It is difficult to measure progress when the parameters are constantly shifting.

In order for the body to produce an adaptation for improved performance in life, sport, or martial art, we must apply specific stimulus as per the SAID Principle (Specific Adaptation to Imposed Demand).

This basically means that the body adapts with a specific type of fitness to any demand which is imposed on it.

When the same exercise is performed for too long, the body adapts to the stresses of each set and the adaptations or returns get smaller and smaller.

Once it has adapted to the stress, then it’s time to change or increase the stress or else we fall into that trap of diminishing returns.

Usually though it takes the body a period of 4-to-6 weeks to adapt and then it is advisable to begin changing exercises.

This does not mean that we need to completely throw away everything we have been doing; far from it. An exercise or drill can be changed by increasing intensity, increasing volume, decreasing rest periods, or increasing complexity or sophistication.

Warrior Fitness Training Principle # 9:

Specific Training + Frequent Practice = RESULTS

Instead of training randomly and getting less than ideal (random) results, a properly organized training program with incremental progression of increasing complexity and sophistication will actually prepare the body much better than a set of random skills strewn together with a nebulous outcome in mind.

How do you properly organize a training program for internal strength? <<==

Train the Body, Everything will Follow

Posted on February 13, 2020 by Jon

How do you get great at so many different facets of martial art at one time?

What one thing can you do to bring up your game across the board, no matter what are you practice?

Train the body.

✅ Want to get better at grappling? Train the body

✅ Want to get better at striking? Train the body

✅ Want to get better at weapons work? Train the body

✅ Want to become more powerful? Train the body

✅ Want to become harder to throw? Train the body

Why does this work?

Your body is the delivery platform for every skill in martial arts. Thus, if you properly condition the body, you improve your ability to acquire higher and higher levels of skill across the board. Build a stronger foundation and the tower can go much higher.

Once you build a highly conditioned body for martial arts, all your other skills instantly become much easier to train.

Instead of focusing on all the many different skills, weapons, tactics, techniques, etc. in the martial arts, look at the one commonality between them all – YOU. To be more specific, your body.

If you put in the work at the level of conditioning the body, ALL your skills improve. You are focusing your energy on creating a body specific for budo. This type of training precedes all of your techniques. It builds a stronger, broader foundation so that any skill you choose to work on is automatically improved!

Over the past 30 years of training in martial arts, I have been privileged to cross-train in many different arts from Jujutsu to Karate to Russian Systema to BJJ and MMA to Krav Maga and Combatives to Internal Arts and weapons training. In each of these I was able to, not only hold my own, but develop a remarkable degree of skill in a very short amount of time – why?

Because I developed a system to train my body that crosses over EVERY art.

Do you want to keep struggling to reach your full potential or do you want a specific, proven, step-by-step system to get you there?

Train the body and everything will follow.

The Year of Strength

Posted on January 1, 2020 by Jon

I have dubbed 2020 “The Year of Strength”.

Why?

Because in strength is what holds us all together.

The strength of love.
The strength of family.
The strength of relationships.
The strength of community.

Yes of course the strength to physically defend ourselves and others. But also the mental strength to make the right choices. The spiritual strength to move past our own physcial and mental/emotional limitations and still be able to keep going when people depend on us or circumstances align against us.

The strength of character to do the right things even when no one is watching or holding us accountable.

The strength of will to persevere no matter what type of challenges life may throw at us.

In my philosophy, as you know, physical training is the microcosm of the macro. The strength of body translates over into all aspects of our lives and our psyche. Being stronger physically makes all of us more useful to each other and of course harder to kill. 🙂

So look forward to much more coming your way to give you all the tools you need to strengthen all 3 parts of yourself – physical, mental, and spiritual – from Warrior Fitness this year.

Happy New Year, my friends. Let’s make it a STRONG one!

Stronger Every Day!

PS – Looking for a crucible of physical training to put yourself through this year? Want to come out stronger, harder, leaner, and vastly healthier in just 6 short weeks? Warrior Fight Club training starts tomorrow – get in on the action HERE!!!

Powerful Morning Ritual To Start Your Day

Posted on August 7, 2019 by Jon

Here is a great way to set yourself up for success on a daily basis.

Spend the first hour of each day working on your own personal development. Discipline yourself to get up earlier and work on yourself each morning – This powerful practice will literally transform your life!

The Hour of Power

Step 1 – 5 minutes is dedicated to gratitude

Practice being grateful for all the people in your life and everything you have. When you start from a place of gratitude each morning, it’s much more powerful to begin each day from a place of abundance, realizing just how many things are going right in your life, rather than coming from a place of lack.

Step 2 – 5 minutes for writing your goals

Take a fresh sheet of paper and write out all your goals on a daily basis – health goals, financial goals, personal development goals, relationship goals, career goals, etc. When you write your goals make sure to write them in the first person and as if they are already accomplished.

For example, if you have a goal to earn one million dollars in your business, you would write – “I earn $1,000,000 in my business.”

Step 3 – 10 minutes of meditation or visualization (prayer fits in here too)

Visualize your goals as if you had already achieved them.

Every morning I sit down on the floor, close my eyes and focus on my breathing.

After each exhale I retain the breath because this is when your body is most quiet – after an exhale, before the next inhale – and silently say to myself, “Every day in every way I am getting stronger and stronger. Every day in every way I am getting better and better.”

I say it several times while holding the breath on the exhale, each time more intently.

When I open my eyes, I am clear, focused, charged up, and ready to start my day!

Here’s a short video I made describing the process…

Give it a try and let me know how it works for you!

Step 4 – 20 minutes of exercise – begin with mobility and deep breathing with bodyweight exercises.

Do you jump out of bed every morning brimming with energy, ready to take on the day? Yeh, me neither. 🙂

What I have found is that doing 3 simple exercises as soon as I get out of bed in the morning helps to rev up my energy levels and kick start my day.

Tomorrow morning, and every morning after that, I want you to perform the following 3 exercises. You will be amazed at the powerful effect they have on stimulating your metabolism and getting you ready to kick butt for the day!!

What are the 3 exercises?

Breathing Push-ups x 10
Breathing Squats x 10
Breathing Leg Raises x 10

For each exercise, exhale fully and deeply (diaphragmaticly) while lowering down, and inhale fully and deeply by expanding the belly when raising the body. Make sure to fully actualize the breath in every movement.

That’s all. Just one set of 10 for each of those 3 exercises to kick start your day.

Step 5 – 20 minutes dedicated to reading

Great warriors train all the time. Reading is a form of training that must be practiced by the warrior on a daily basis. Feeding and training the mind is just as important as feeding and training the body. Remember – knowledge is power!

Fill your mind with creative, positive and motivational ideas, concepts, and philosiphies – reading is the key to success. Learn something new every day!

Here are 10 books that are a must in every warrior’s library. Expand your mind and pick up these books!

(PS – don’t have a full hour in the morning? change the amount of time spent in each area to fit your schedule)

You will find this powerful practice a great way to start your day and propel you towards success in every area of your life. Make sure that you implement it tomorrow morning!

21 Day Wuji Standing Meditation Challenge

Posted on March 26, 2019 by Jon

21 Day Wuji Standing Meditation Challenge

Why Wuji?

The health preserving and sustaining effects of Wuji Standing have been documented in hospitals and medical clinics across China.
The reason this practice has such a profound impact on health and recovery from exercise is that the standing meditation acts like a system-wide reboot for the whole body.

It stimulates the nervous system, increases circulation, and raises energy levels, while providing deep relaxation for both mind and body.

Aches, pains, old injuries, muscular tensions, and imbalances are highlighted and brought to the forefront by this method and then slowly dissolved over time and completely released.

The practice provides a way of completely relaxing and letting go of the muscular tensions in the body, while the correct alignment of the bones delivers support, creating a profound neutral and relaxed, almost buoyant state.

As the whole body and mind are exercised, both relax and stimulate the nervous system, increasing circulation, opening the joints, and raising energy levels for a feeling of overall well-being.

This exercise looks easy from the outside. After all, you’re just standing there and not moving. However, there is a lot going on inside: the breath and qi (energy) are moving.

This exercise is a challenging, sometimes frustrating, yet highly beneficial and rewarding practice. The only way to truly appreciate it is to experience it for yourself.
