Z Health: The Most POWERFUL, and infuriating, Fitness Tool

Lessons from a Fit life.

This is the power of Z health: Her back pain went from a 9 to a 2 after tracing the alphabet with her finger. It took :30 seconds.

He couldn’t lift his arm past shoulder level for years, then whacked his head with his bicep after doing a vision drill. :20 seconds.

He couldn’t move his neck following a medical emergency, but restored full range of motion by holding his breath and doing squats. :60 seconds.

I am not brilliant, and I did not stay at a Hiliday inn express. I study z health.   It is simultaneously the most powerful and infuriating fitness tool kit available.

What is Z health?

I’m going to leave something out but here we go. The core beliefs of Z health are:

  • Everyone is an athlete.
  • Your body is wired for survival, not performance.
  • If one move can get you in pain, one move can get you out.
  • It all starts with your brain. Every voluntary movement you make is created by your brain. If you want to really change the way you move, you have to start by changing the brain.
  • Your Brian needs fuel, and activation to work optimally.

Highlight that 2nd to last one.

It’s what makes Z health so frustrating. The brain, all things considered, doesn’t work the way most people would think it does. To change the brain you basically have to do some really odd, seemingly random things.

Like tracing the alphabet with your index finger to relieve back pain; or doing an eye drill to relieve shoulder pain; or holding your breath to restore mobility.

People fight me on these. People who pay for my “expertise”. If you have neck issues and I say hold your breath you’re going to have questions.

Be that as it may, I also thought it was BS until I saw it work over and over again.

Time for an example

We tried everything; his neck wouldn’t move. We tried mobilizing the muscles of the neck; We tried mobilizing the muscles above and below the neck; We tried massage; We tried gliding and slacking the nerves.

I could go on, but you get it: his neck wouldn’t move.

Working with problems like this is frustrating. You make educated guesses and then test to see if the guess worked.

Nothing was working.

I went back into my Z health training. The brain is wired for survival. It was limiting motion in the neck to protect him.

From what? The tissue wasn’t damaged, nor was the surrounding musculature. There wasn’t any physical trauma to the neck.

Ok… what do the brains/muscles need? Fuel.

Fuel comes in the form of gaseous exchange “mainly focused on oxygen and carbon dioxide exchange and maintaining a healthy ratio of carbon dioxide in the body.”

Was the brain not receiving enough fuel (aka Oxygen)? Let’s test.

He held his breath and performed 10 squats. Holding his breath increased the amount of CO2 in the blood which pushed the Oxygen out (see the Bohr effect) delivering more fuel.

Wait a second? Holding your breath delivers more oxygen???

Your starting to see what I’m up against w Z health.

Back to the story:

His neck moved. It moved like it hadn’t in years. It move like nothing had been wrong minutes before.

His reaction was priceless: a stunned look. Then he stopped, looked me in the eye, and said “This is bullsh*t.”

He’s kind of right.

Neck pain isn’t about the neck.

It’s about the brain.

All pain is.

All movement too.

That’s Z Health. It takes you down some weird paths; it often seems like total bs; but the results speak for themselves.

What is Kinesio tape (K tape) and Does it actually work? Let’s get down to it.
I woke up sweating.  4 am.  I sat up, stared out the window and the room swirled.  Something was amiss. My balance was gone.  Any time I turned left I felt I was going to crash.
Once upon a time sneaker engineers tried to outsmart millions of years of evolution and fix our feet by adding a raised heel, air blown rubber, increased cushioning, thick tread, and support (via dual density foot bridges and rigid soles).  And by and large the rate of foot and leg injuries stayed the same.
