In this video you will see an example of Human Spring at it’s highest-level of athleticism.

Bob Beamon

Bob Beamon broke the worlds record in the long jump and it stood for two decades!!

Beamon set this world record for the long jump with a jump of 8.90 m (29 ft. 2½ in.), bettering the existing record by 55 cm (21¾ in.).  When his teammate and coach Ralph Boston told him that he broke the world record by nearly 2 feet, an astonished Beamon collapsed to his knees and placed his hands over his face in shock. In one of the more enduring images of the games, his competitors then helped him to his feet. One journalist called Beamon “the man who saw lightning”. Sports journalist Dick Schaap wrote a book about the leap, The Perfect Jump. Prior to Beamon’s jump, the world record had been broken thirteen times since 1901, with an average increase of 6 cm (2½ in) and the largest increase being 15 cm (6 in). Beamon’s record stood for 23 years.

This is one of the greatest feats of athleticism in this century.

Watch how he runs to break this record. More importantly watch at the end when he is walking. It’s very interesting.

How does the body absorb or spring back from the impacts of walking, running and the performance of sports such as plyometrics?  

The answer: The human body is a marvel of human spring engineering.

It is important to have strength in your foundation to protect your body from impacts as well as help with balance, agility and coordination.

 Click the links below to strengthen and supercharge the spring suspension muscles system muscles:

This spring mechanism has a leaf spring (which absorbs impact without muscle contraction) it is suspended by the spring suspension system muscles.

1.  The Arch Leaf Spring – There have been studies on the arch with all muscles removed leaving just the bones and ligaments.  These were extracted from cadavers.  What the study showed was that the arch complex itself has the ability to spring back forces without the aid of the muscles.

 2.  The Spring Suspension System Muscles – I coined these muscles as the spring suspension system muscles, the landing muscles or the pronation-supination cuff muscles.  I identified this new medical terminology myself in order to better explain the function of this area.
I did not like the way it was explained in the text books and scientific literature because it confuses people so much that they give up trying to understand how it works.  That is where you just give in to what ever anyone says and you become a victim or drone to who ever is directing you.


Does it take up impact forces as a lever as they see it,

or as a lever and a spring as I see it?

I see the body as a human spring while other doctors and scientists see it as a lever.   I will prove that the body is not a lever in this post with common sense reasoning, something not so common in medicine.

The first step in our understanding of the human spring is to understand how the arch works through the muscles and tendons that attach to it and control it. I call these, the spring suspension system muscles!

As you can see from the video above, there is a tendon that appears through the medial aspect of the ankle. That tendon has strategic attachments at the first and second metatarsal cuneiform joint. The name of this muscle is the tibialis posterior.

The muscle loops around the medial malleolus and attaches on the posterior fibula. (see the picture below)

It’s interesting that we don’t have any exercise machines or exercises to develop this muscle in the gym. Its what I call the missing training routine!

AKA Pronator/Supinator Cuff Muscles

The tibialis posterior, tibialis posterior, peroneus longus and brevis form the pronator/supinator cuff.  Like the rotator cuff, these muscles stabilize the foot and ankle in the “safe range” between the rolling of the impact force from supination to pronation (inside to outside)

Doctors Argue About What Over Pronation Is And What Causes Over Pronation

So many medical specialists talk about over pronation, over supination, being a pronator or a supinator and within their own profession they argue about what it is and what causes it.  This is the core of what causes the majority of conditions in the foot and ankle and what runners focus on when they buy shoes (braces)

When any bone or bony complex (like the foot and ankle) moves out of the safe range of motion it is ALWAYS because of a weakness in the muscle or muscle group that controls this movement or stabilizes this bony complex.  Dr Stoxen

Introducing… The Rotator Cuff of the Shoulder

At one time we did not know what caused instability of the shoulder girdle.  There was a time when we did not have awareness of the important supportive function of the rotator cuff to stabilize the shoulder so the primary movers could do their work without injuring the shoulder.

Introducing… The Pronator/Supinator Cuff of the Foot and Ankle

So, if you want to know why your foot and ankle rolls out of the safe range just look at the muscles which are responsible for this movement and you solved the riddle.  I made this determination based on solid training principles because I wasn’t TOLD or INSTRUCTED on what caused it based on some text book.

How do the Pronator/Supinator Cuff AKA the Spring Suspension System Muscles Work?

I will teach you how these muscles work and show you innovative exercises that I have found and developed that you can use to improve your ability to spring back from the various impact forces of landing such as:

  • walking (1.25 x bodyweight)
  • running (3x bodyweight)
  • plyometrics (3-5x+ bodyweight)

The body springs off the ground when its working the way its designed.  The natural spring mechanism occurs at the arch and transfers its protection and spring energy through the 7 floors of the human spring.

The body is a giant spring with 7 floors of springs:

  1. The arch
  2. The subtalar joint
  3. The ankle mortise
  4. The knee
  5. The hip
  6. The spine
  7. The head-neck

There are two mechanisms that allow spring to happen at floor one:

  1. The configuration of the arch with the 26 bones and the ligament attachments.
  2. The spring suspension system which is composed of the muscles and tendons that attach on the under surface of the arch.

In the walking or running game, whether you are running for weight loss, running to prepare for a 5K, 10K, half marathon or marathon or running for your life, the key to this game is successfully absorbing each impact.

Regardless if you use Chi running, pose running or human spring running, the key to avoiding abnormal movement patterns from a weak or locked human spring that cannot effectively absorb impacts is to have NO spasms or locking of the joint play in the entire spring mechanism and a strong spring suspension system for this three dimensional structure.

Spasms in the muscles that cross a joint or two joints cause the joints to become compressed and when we apply this understanding to the human spring model, spasms cause a preload internal compressive force on the human spring.  This preload internal compressive force reduces the overall force of impact capacity you can load into the spring mechanism.

  1. When your spring mechanism gets weak your spring mechanism collapses into a lever mechanism.
  2. When it collapses, the brain senses the abnormal movement patterns of walking as a lever and tries to protect you from the stress and strain by tripping spasms.
  3. Spasms compress the spring further.

What about you? If you are having these spasms what should you do?

It is critical for you, your coach and your doctor to

  1. Understand what causes these spasms like abnormal movement patterns
  2. How to check for them like gait evaluations and hands on deep tissue palpation
  3. how to remove them to insure there is no internal compressive force preloading the spring mechanism.  This is done with muscle spindle work and other hands on treatments.

I developed a 3 step approach to enhancing spring loading capacity:

  1. Release the compressive forces on the human spring
  2. Strengthen the spring suspension system muscles
  3. Impact train the spring suspension system

This three step approach will help you expand the force loading capacity of your human spring to better spring off from impacts, to have maximum performance and reduce risk of injury.

What does the human spring suspension system muscles do?

The human spring suspension system muscles help you spring off the ground.

What if the spring suspension system is weak, fatigued or locked?

Or what if we didn’t read the owners manual that came with our pogo stick, I mean human spring mechanism?

To help you learn more read the two posts below:

Video Tutorial #169 How To Land Your Foot When Walking, Running And Barefoot Running, click here

Do you know how to walk and run the right way so you don’t damage your joints?

When you are not springing off the ground then you bang into the ground (foot plant) and twist off the ground (toe off) when you walk, jog, run or participate in sports or leisure activities.

Obviously springing off the ground provides better protection from impacts and allows for a more efficient recycling of energy through this natural spring mechanism.

What you need to do is study the engineering in detail so you can develop the best treatment, training and maintenance for your human spring.

Why do you need cushions and braces on your feet when you run?

Why does grandma need:

  • Orthotics
  • Orthopedic Shoes
  • A cane
  • A walker
  • A wheelchair
  • A hospital bed

The doctors said her muscles could no longer support her.

Maybe its a good idea to learn how to condition your spring suspension system muscles of your body for impacts instead of looking for the next brace?

So, before you get up and running, you are going to want to learn about the engineering of the human spring and specifically what the spring suspension system muscles are and how they assist you in springing off impacts safely.

As you know I also refer to them as the landing muscles, the pronation supination cuff or the arch foot and ankle sling muscles, as one famous doctor from Bangkok, Thailand called them.

Most of you work on your “take off” muscles yet the “landing muscles” are hardly EVER exercised because so few even know they exist!

Dont you think that if you put a bigger, more powerful and heavier engine on a plane that it would fly faster?  You might want to put a stronger landing gear on the plane too?

With this simple logic, why are so many of you training the take off muscles and completely neglecting  the landing muscles?  

No wonder you have so many impact related injuries like plantar fasciitis, heel pain, stress fractures, shin splints, knee pain, hip pain and herniated discs!

So many people are told that impacts are bad for you in running.

That is just wrong!

Impacts are only bad for you if your human spring mechanism cannot handle the force of the impact safely!  Period!

So what’s the difference between you and them?

The idea that you have to have cushioned footwear to absorb the force of the impacts doesn’t really make sense, unless the impact resistance mechanism, the spring suspension system muscles and mechanism cannot handle the impacts.

So if your doctor, your coach and your conscience told you that you needed a cushion between yourself and the earth to absorb the impacts I guess what they were really saying was YOUR spring suspension system muscles and joints are not healthy enough to take the impacts but other peoples are.

 Is the human body a lever or a spring?
The first thing we have to determine is what the human body is in the world of physics so we can better understand the model of the object that has to collide with the earth 100,000,000 times before our 30th birthday.There is a fundamental difference between the way I see the human body and the way most other doctors and scientists see the human body.
I say that the body works as a lever and a spring.
Most doctors and scientists say human body ONLY works as a lever systemI think it is because they still memorized the old text book instead of observing how it truly works to protect us from impacts.

I also think that maybe its because the spring mechanisms of the patients that levered into their clinic with pain already had their spring mechanism lock up before they walked into the office.  When they observed them it was while they were limping into their offices with their levers so they could sit or lay down during the examination of their locked levers.

How many doctors see top athletes doing double fullsstanding fulls, or plyometric drills?

Many just recite “the body acts as a rigid lever at take off”.

You can tell when they talk like that there is no independent thinking.

Why is the body NEVER a rigid lever during running or walking?

At the same time it is loading from the force of the landing like lowering a weight on the bench press.

With all that rolling and loading in a three dimensional plane across 33 movable joints it never becomes a rigid lever!  Its just impossible to think that can happen with a rolling loading bag of 26 moving bones.

For me, with my experience studying impacts in sports such as running, jumping and  plyometrics, I find it ridiculous to think that the body absorbs these incredible impacts with levers.

How can a lever protect two objects (earth and human) that predictably will collide over 250,000,000 times in a lifetime?

Lets see… this object will collide with the earth 250 million times so lets design it as a lever.

Are you thinking what Im thinking?

It doesn’t make sense!

Is it just me or do you think it’s hard to imagine that we can launch our 150 pound bodies against 450 pounds of impact resistance force for over 26,000 consecutive impacts with ultimate efficiency as a lever system.

If you believe what you are saying, then you are saying that is the way you launch your body against this 450 pounds of resistance or approximately 11,700,000 pounds of work load!

The same person can’t do 200 calf raises (working as a true lever) amounting to 30,000 pounds of work.

Here are the exact formulas:

  • 26,000 impacts/26 miles
  • M x A = F      (M)150 pounds x (A)3 = 450 pounds force per impact
  • 450 x 26,000 = 11,700,000 pounds of impact over the course of that marathon
  • 150 pounds x 200 total calf raise reps before exhaustion = 30,000 pounds of work

Why do we become exhausted at 30,000 pounds of work during calf raises (working as a true lever) but can run 26.2 miles for 26,000 impacts of 450 pounds of force amounting to 11,700,000 pounds of work?

Why the body is both a lever and a spring….

  1. The body works as a lever mechanism when doing calf raises.
  2. The body works as a spring mechanism when running.

Its obvious which one is more efficient!

Do doctors and scientists disagree with me?

You wouldn’t think so but they still hold on to this lever model!

OK OK the body does work as a lever and a spring.

Does that make you happy?

In my opinion, the body does move at as a lever system such as when we are going up on our toes, walking up stairs, doing raises, but it also functions as a spring mechanism when we are walking, jogging, running, and participating in sports activities.

If we look at the body as a spring mechanism we have more effective ways of treating and training the body than as a lever.

Also looking at the body as a spring mechanism helps us explain many mysteries that baffle doctors and you.

Like…. CHRONIC PAIN – The body bangs and twists into the ground 10,000 steps a day (walking) rather than springs off the ground so it cannot protect itself from the impacts resulting on an assault on the muscles and joints.

Maybe that is why my plantar fasciitis, heel spurs, shin splints, knee pain, hip pain and herniated disc won’t heal!  

Like… CHRONIC FATIGUE – The body bangs and twists into the ground 10,000 times a day (walking) rather than the more efficient way of ambulation, springing the mass off the ground.  (some have estimated that 25-60 percent of the energy is recycled through this spring action)

The human body abides by the Hookes Law of Physics

Hookes Law applies to spring mechanics.  It does not apply to lever mechanics.  Read this article I wrote and give me your comments at the bottom.

The Human Spring Model and Approach in its Relationship to the Hookes Law of Physics

When you think about impacts there is a force that impacts your body on each landing. If we understand how this force absorbs into our body safely then we can look at those structures that absorb the force and release them, strengthen them and supercharge them for optimum performance.

Then we can run barefoot because we won’t need an artificial cushion to do what our human spring is designed to do for us!

Why don’t doctors and scientists let go of the lever model for the more accurate spring model of evaluating, treating, training and maintaining the human body?

Why do they still hang on to the lever model if it doesn’t make sense?

They can’t prove it is a spring by EMG testing because EMGs don’t measure the spring of tendons and connective tissue complexes (the arch)  

Most of the muscles that control the safe rolling of the foot from supination (outside) to pronation (inside) and the spring action of the foot originate outside the foot on the calf.  They become tendons in the foot.

The muscles have strategic attachments at the underside of the foot where the spring action occurs but they originate in the calf.  (see the illustration below)

I have been a guest doctor at track and field championships examining healthy springy feet and evaluated the springiness of the feet of every patient that comes in my office.

Coaches, trainers  and managers send me athletes and entertainers to tune them up to improve their performance.  They do not have any injuries. I evaluate them head to toe nail to see what areas we can release to increase their spring performance.   I know what a springy, fully released human foot is supposed to feel like.

I work 10 – 30 hours on stiff or locked feet to remove preloaded compression forces by deep tissuing out every single spasm and releasing every single joint to maximize the ability of the foot to load impact forces into a spring mechanism safely.  When Im done, the feet feel a much different than they did when they started.  More springy!

Imagine how springy your feet and legs would feel if a deep tissue specialist worked 30 hours releasing the tension and spasms on your lower body!

There is a huge difference in the springiness of the foot of a patient with a plantar fasciitis, bunions, chronic knee pain and or herniated disc that hasn’t healed.  Why do I know? Ive been working on thousands of feet with my hands for 25 years, 6-7 days a week a minimum of 10 hours a day.

Feet that have stiff muscles around them or have locked joints function as a lever mechanism so they cannot absorb the force of the landing as effectively .

To think any differently violates the laws of physics!

Lets see…  A stiff foot or a springy foot….

Which one is going to bang on impact?

In the examination of the walk you often see the calf muscle shake on impact with a patient who’s foot is locked.

That tells you right away there is no spring in that step!

If you have plantar fasciitis, foot or heel pain, heel spurs, calf pain or swelling, shin splints, knee pain, hip pain or back pain, walk barefooted (shorts too) towards a camera and away from it fast. When you look at the video watch to see if your calves shake.  You might be amazed!   I did a post on you might like titled,

In order to absorb millions of impacts it must be designed as a spring mechanism.

When the Spring Mechanism Breaks Down it Becomes a Lever Mechanism

What about the studies?  Are their any studies that prove what you say?

Almost every gait study done in America or anywhere except a third world country will provide inaccurate data that will confuse you into thinking that the human body moves, protects you from impacts and recycles energy as a lever mechanism rather than a spring mechanism.

How can I say that?

If a scientist selects a study group from people who have worn shoes for 20-30 years then the human spring mechanism has been tampered with extensively and therefore the results and interpretations and conclusions from these studies are not as helpful to prove the body is a spring vs a lever when it is working right!

Imagine if we were doing a study of elbow movement and decided to use a student who had a brace on his elbow for 20 years and another who did not have any braces on the elbow his whole life.

Are they going to have different elbows with different movement patterns and strengths?  Of course they are!  Logic!

One would have to study how normal healthy children walk who have never worn shoes or habitually barefoot subjects from some third world country would have to be selected.

The other problem with the way gait is studied is, the subjects are commonly selected who are pain free.  That doesn’t mean there isn’t already substantial plastic deformities and locking of the spring mechanism represented by a locking of any one or many of the 33 joints of your 26 bones of your foot.

People have advanced bunion deformities that are painless that obviously effect impact resistance.  The reason why these deformities happen without frank pain is because we take about 50,000,000 impacts into each foot by our 30th birthday.  Even subtle abnormal loading position of the foot can cause a lot of deformity in that many impacts.

Did someone qualified to evaluate for the joint motion of all 33 joints check these subjects before they were included in the research?

You rarely see a doctor do motion palpation of each individual joint of the foot to make sure they are all moving according to the way they were designed even when the patient has a condition like plantar fasciitis, Mortons neuroma, heel pain, bunions, calf cramps and the list of spring compressive conditions goes on up the floors of the human spring.

In fact I once had a doctor question me when I suggested that the most commonly locked joint of the foot was the second and third metatarsal cuneiform joint.

He suggested it wasn’t supposed to move because it was a saddle joint.

If it is a joint then it is supposed to move!  What are you talking about?

Why would the joint be there if there was no movement needed there?

I guess if he believed it was not supposed to move he wouldn’t have to examine the joint for movement there.  If he believed there was no movement there in the mid arch then he would not feel so guilty locking the arch up with an orthotic from the bottom and the shoe from the top.

Why do we have joints?  

To protect us from impacts!

How do we check for joint play in a joint?

I was not taught how to evaluate for loss of joint play in a joint and for abnormal movements in the spine for all my years in chiropractic college.  I had one (2 credit) class on examining and adjusting the extremities such as the foot and ankle but there was not so much emphasis on it as I put on it now.

I make sure there is no restriction on any joint from the tip of the head to the toe nails on every patient.  

I learned how to evaluate for restrictions on the joint play affecting the ability of the body to load the forces of the impact into the spring mechanism by absolute necessity.

My first patient started off the education process of human spring!

My very first patient was powerlifter, Ed Coan, as described as “the greatest powerlifter in the history of the sport“…

For more information on The Ed Coan Story – What I Learned from the Strongest Man in the Worldclick here

If the doctor doesn’t  even have the skill set to be able to evaluate the joint play in all 33 joints of the human foot and after that if he cannot manipulate these joints then he can’t understand how the locked joints behave differently when it is in fact released. He has nothing to compare.

I can tell you that when you release the mid foot locking and the metatarsal cunieform joints of the foot,  there is a loud cracking noise from the release of the fixation.

Watch the video below of me resetting the talus in the ankle mortise.  The sound of the release of the locking of this joint may startle you!

Many patients say afterwards it feels more bouncy or springy when I walk.

It just makes sense!

Whenever the foot rolls out of the safe range into a over pronation position, the ankle joint is affected. This over rolling stresses the ankle joint and many times the talus bone which is like a ball bearing of the foot, jams into the joint above called the ankle mortise formed by the extension of the tibia and fibula.

When I trained for 3 months running barefoot in zig-zag patterns I noticed a huge improvement in my foot-ankle alignment.  If I tried to over pronate, my pronation/supination cuff muscles would immediately “snap” my foot back into the safe range!  I have noticed the differences in my patients as well.  

Why use a brace like an orthotic or motion control shoe when you can train your body to correct its own alignment?  

How can you treat a patient with a knee cap misalignment in the trochlear groove which is essentially a pulley mechanism without addressing the ability of the foot to plant without torquing the tibia and fibula out of alignment with the knee cap?  Think logic!

To read more about Cracking Achy Knee Pain or Chondromalacia Patella – Treatment and Prevention Tips from The Barefoot Running Doctorclick here

When you look at it, it looks like a saddle on a horse’s back.

When I make adjustments of the talus that is jammed in the medial aspect of the ankle mortise, the release of this joint makes a very loud audible crack or release. Here is a video of me below releasing a talus joint locking.

How else does this “locking” of the many joints of the human foot affect movement and development?

If muscles pull against the joints they must be moving for the muscle to get full contraction and full development.

This is obvious!

Just think of how much development you’d get from your bicep during a curl if your elbow was completely locked.

The lever system model claims that the body becomes a rigid lever as if it’s some kind of stiff unit when it pushes off.  

If that was true, then the forces of the impacts of between 300 – 800 pounds would literally destroy the cartilages in a short time and end plates of your bones if it became a solid unit.

I contend that during running for sure that the foot is never an 180 lb  solid unit unless it’s locked or frozen.

But if it’s working right it’s in a constant elastic deformation process, constantly moving the load across the ever-changing deforming structure that  protects you from these impact forces and stores energy only to release it for maximum efficiency.

It’s ridiculous to think that it’s okay to have joints locked up and that it won’t affect the development of the muscles control the landing and absorption of impact forces.  If you don’t check for the joint play in these important joints then you may be missing something very crucial in the treatment of the patient!

As I said many times the primary landing muscles, the spring suspension system muscles that load the force of the impact into the spring mechanism and release the energy or  unload the forced back into the mechanism I refer to as the spring suspension system muscles.

You won’t find that word or concept in any book or taught at any school because I coined the muscle group to fit the human spring model because it was not possible to explain what was available in the human lever model.

The muscles that absorb the forces of the impact are the tibialis posterior, tibialis anterior, peroneus longus and peroneus brevis and a few others up the floors 1-7.

The impacts are also absorbed from other muscles such as the soleus however we are always developing those muscles.  Exercise is needed to supplement what we are NOT exercising in our daily lives.

From my clinical experience, the majority of the people who have injuries from running such as plantar fasciitis, shin splints, heel pain, torn cartilage in the knees, hip pain and herniated discs are because the spring mechanism can’t effectively absorb the impact into the spring.

Because the human spring is preloaded with compressive force from muscle spasms and locking of joint lay there is no room to load all the impact force.

Because of that, the impact is absorbed into the tissues as chronic stress and strain, wear and tear inflammation and pain called degenerative joint disease during running or simple walking.

Then you have the acute injury resulting from an acute overload of the force of impact into the compression spring, the vertebral disc, which is really a plastic deformity.

I explain elastic vs plastic deformity in depth in:

Video Tutorial # 143 What I Learned From Studying Javier Sotomeyer Technique About Improved Performance and Reducing Injury Riskclick here to view

In the knee we call it torn cartilage.  In the foot or shin or tibia bone we call it  stress fractures.  When the preload compression force overloads the compression spring of the lower back it causes a plastic deformity of the disc or a herniated disc.  If the overload is severe acute with no room to absorb the forces into the mechanism you can have a fracture or fractures.

Damage to ligaments, tendons, cartilage, bones or discs occurs when the force of the impact exceeds a spring mechanism’s capacity to store the impacts either over time as a plantar fascitis shin splint, heel spur or cartilage wear or instantly as a herniated or bulging disc.

The spring suspension system muscles help absorb impacts.

All joints that are involved in absorbing these impacts must be moving.

If the joints don’t move where the tendons attach then the tendons cannot pull against these joints.  That makes it impossible to get full impact force into these joints and it’s also impossible to get full positive adaptation leading to maximum development of the muscles, tendons and connective tissue of joints.

The body does not only use muscles to propel.  The arch would spring back impacts even without the muscles just by its very design. 

The arch configuration is 26 joints wrapped by ligaments and this connective tissue that forms a springy bow or leaf spring, that adds impact resistance and free energy to impact activities such as walking, running and the performance of sports.

Footwear alters movement patterns in the foot and most footwear either binds, deforms or reverses the human spring mechanism.

A few doctors and academics have argued with me that there is no scientific proof that shoes binds or restrict movement in the foot.  

I agree that assumptions must be based on peer review literature, however I do not need peer review studies to tell me that a shoe that I wrap around the foot and lace tightly does not alter the movement in any way in the foot or the joints above.

People who talk like this either work as consultants for footwear companies or will wait for 30 years for 10 studies to say it does while thousands of patients have rapidly deteriorating health because they are treated the opposite of what is best for them in the long run. Meanwhile they wait for someone to do a study that tells them what they already know.

It is obvious that footwear binds the foot and alters the natural movement of the foot to some degree. Each style of footwear and the size of the shoe etc. determines how much it binds the foot. If it did not bind in some way it could not stay on your foot.

Do you think you can attain full range of motion in adduction, abduction, inversion and eversion of the foot with a shoe on? No way

How can a body part attain full range of motion in abduction, abduction, inversion, eversion, supination and pronation when there is a piece of leather wrapped tightly around it?

This is where they contradict themselves!

On one hand, footwear companies and doctors say that you have to wear shoes to support the foot which means that it’s applying a pressure to the foot to provide the support.

So just by saying that it supports a foot you are admitting it affects the movement of the foot, period!

I’ve had arguments with other doctors in forums where they say show me the proof that the shoe inhibits the movement of the foot. Then in another forum topic they will say that the shoe supports the foot and therefore it’s an important item to wear when you’re running because your body can’t absorb the force of the impact as a lever.

They contradict themselves!

If shoes give an athlete a competitive advantage then isn’t that a form of cheating?

No athletes train with implements or braces if they KNOW they give them a lift or advantage because they KNOW this takes away from the positive adaptation they need to get stronger.

Do you tell your friend to lift the bar off you at 3/4 way up or grunt out that last rep yourself?

When lifting you could injure yourself so why not wear a brace on every joint of your body?  Im sure some doctor could convince you this is a good idea!


I remember in the early 80s, I was the doctor for the American Powerlifting Federation for six years, 1986 to 1992.

To hear more about the beginning of powerlifting in the soviet union watch

Historic First Sports Medicine Course In Russia – Sports Chiropractic Journal – August 1989, click here to view

At that time these new bench shirts were coming out. What they were was a  T-shirt that was made from a very tight fitting elastic nylon material which protracted your shoulders into the extreme negative position related to the bench press.

watch this video to see an example of how a bench shirt was used,  Johnnie Jackson puts on bench shirt at 2008 USPF Nationals

When athletes would load the weight on their bench, they lowered the weight into the muscles and tendons and at the bottom of the bench shirt it stretched and helped them to propel or push the weight up off the bench which added about 40 pounds to their maximum bench press.

You’re wondering how they got away with that!

They made claims that the bench shirt was developed that way to prevent injuries during the bench.

Doesn’t that sound familiar?

The difference is that the athletes were smart enough about principles of training never to train with the bench shirt.  WHY?  If it helps you to do the bench press BY LESSING THE STRESS ON THE JOINTS AND MUSCLES then you are not allowing your body to adapt to the weight and get stronger!

They just put the bench shirt on a week before the competition to make sure it fit right then ONLY used it to try to get some extra boost to win the competition or break a record.

Was the record legitimate?  Not to me!

If you cannot get full range of motion on the joints of the foot with a shoe on, then you cannot get full adaptation.

Test your foot motion with and without a shoe in full inversion, eversion, adduction, abduction, pronation and supination motions and I guarantee you will feel the shoe material restricting you because the sole is a stiff unit that prevents the full range of motion in movements. Listed below are two exercise posts that you can do to try testing your foot:

  2. Video Tutorial #106 Foot Inversion Exercise, click here to watch

I guarantee you you’re not going to get the same range of motion as if you’re training barefoot.

You cannot get the same adaptation running with shoes as barefoot! Period.

So how do you think you’re going to develop these landing muscles to best absorb impacts when you’re running with shoes?

If your body is a perfect spring, capable of absorbing impacts why are you running with a binding device that has a cushion to absorb the impacts your own body is capable of absorbing?

  • Did some shoe company brainwash you with their Madison Street advertisement?
  • Are you afraid?  You could run barefoot as a child but you are more afraid as an adult than when you were a child?  Be brave…
  • Is it because you don’t have anyone to release the 33 joints of your feet?
  • Is it because you don’t want to do the strengthening drills to strengthen your suspension system landing muscles?
  • Is it because you want to wear shoes that match your outfit?
  • Is it because you don’t want to work on your form and technique and think the shoe will make up for your form breaks and weaknesses?

Millions of people run distances barefoot around the world…..

Check out the Barefoot Runners Society and find a chapter near you. Here.. 

Watch this video below of  former Olympic track world record holder, Zola Budd, who, in less than three years, twice broke the world record in the women’s 5000 metres and twice was the women’s winner at the World Cross Country Championships. She mainly trained and raced with world record speed, barefoot.

Remember F = M x A

That means the forces of the impacts on her foot were greater than any other female runner in the world at that time her same weight.

Its proven with newtons law.  Do you want to argue with me on that too?

Please don’t…. I don’t want you to embarrass yourself.

How do you do run barefoot on the street and not have impact related injuries or conditions.

All I had to do was figure out how to safely load the impact force into my human spring that was represented by the cushion and I could throw those bench shirts whoops! I mean running shoes away.

Even if you don’t want to throw out your running shoes don’t you do want to condition your human spring mechanism to absorb impacts more effectively, more safely and at greater forces or speeds?

Of course you do!

Im a 50 year old doctor who stands on his feet all day working late and still figured out how to take impacts safely into my barefoot human spring without damage and run 9 minute miles in the 5 K without wanting to run fast. watch the video below as I demonstrate barefoot running in slow motion.

 How to strengthen your spring suspension system muscle group.What I recommend is that you train the foot with drills in directions that stimulate the development of these spring suspension system muscles.
RESISTANCE TRAINING – Train with resistance exercises adding cuffs  strapped to the foot moving it in a variety of  directions such as eversion, inversion, abduction, adduction, pronation and supination.

Kids Should Run Barefoot and have Fun and So Should YOU!

It’s interesting that kids seldom have chronic injuries, their spring suspension system muscles are fully developed as they’re running around in free play in the backyard with no shoes on.

This goes on very successfully until mom screams out,

Put your shoes on and stop running around like a crazy kid!”

We don’t realize what we’re doing to our children when we tell them that they should behave and act like us. What we are doing is we are taking them away from the developmental plyometric exercises of leaps, bounds, hops and skips in multiple directions and making them conform to our boring straight path routine that causes us to have an imbalance in the spring suspension system muscles of our body.

As kids we run around in the woods chasing animals, animals that run in multiple directions and as adults we run down the path to try to get to first base then stand around for a few minutes, run to second base on a straight path in then of course there is this matter of having shoes on to protect us from these impacts in different directions that will make us stronger.

The moral of the story is that the spring suspension system muscles must be developed in relation to the amount of impact forces that you are planning on absorbing or springing back from.

These are the fundamental causes of weakness in the spring suspension system muscles.

  1. The spring suspension system muscles are not completely developed by running straight ahead. You must move the foot in all ranges of motion against resistance.
  2. You must develop the foot in these ranges of motion with impact forces that are equal to the amount of impact forces you plan on absorbing. That means if you are planning on running you must run drills in all ranges of motion so that the spring suspension system muscles are able to move and develop.
  3. Footwear inhibits the development of these muscle. So training must be done with bare feet. Shoes only inhibit the movement of the bones so the muscles can’t fully develop.
  4. Start with slower speeds and work your way up adding an increment of speed every two weeks.

Impact Drills and Plyometrics

Your spring suspension system must be completely released during these impact drills.  If you have a locking or more stiffening of any of the joints by either joint stiffness or muscle stiffness surrounding the joints the suspension system that represents a preload force on or a compression of the spring suspension system.

That means that the total capacity to load the force of the impact into the spring mechanism is reduced because it’s preloaded already with some force. If you try to load maximum force into this preloaded spring mechanism there is no room for the force to go.

That is when it has no other choice but to cause injury when the force plastically deforms the disc. This is what we call a herniated or bulged disc.

If the force is overloading the spring mechanism of the knee then you can get a a meniscus tear or anterior cruciate tear.  If it’s in the foot then it can become a heel spur, plantar fasciitis or a shin splint.

These muscles are essential for absorbing impacts so if you’re having impact injuries such as shin splints plantar fasciitis, herniated discs, heel spurs, then you can suspect that your spring suspension system of the arch of your foot is locked.

The most likely area for the spring mechanism to lock is at the metatarsal cunieform joint number two and three.  (mid-arch)  Also the talus can lock in the ankle mortise medially.  When I release these joints they make a loud crack and the patient feels an instant release of the joint stiffness.

If your spring suspension system muscles are stiff the most likely ones are the medial intrinsic muscles of the foot, the tibialis posterior, tensor fascia and gluteus medius.  You can start releasing these muscles by doing the spring release techniques to release these joints in tutorials #77-89, the links are below:
