“Athlete decline with age. Artists improve.” – Zenman

Shane “Zenman” Eversfield, Founder Kaizen-durance

There’s more to endurance sports than fighting the Aerobic Wall.

Kaizen-durance Arts

A cutting-edge endurance training and racing method developed through a lifetime of intensive field-tested research, teaching, training and racing.   

Dr. Andrew Getzin, Head Team Physician for USA Triathlon has this to say about Kaizen-durance:

These insights, techniques and exercises are applicable to the elite triathlete, the middle of the pack racer, and for all of us who seek to maximize return on our aerobic investment for healthy functional and fulfilling lives.   And they are compatible with any conventional training program.

Make 2020 your year for mastery! 

Start here with Book One: 

Kaizen-durance, Your Aerobic Path to Mastery: An Introduction


Again, from Dr. Getzin:

Book One, “An Introduction to Kaizen-durance, Your Aerobic Path to Mastery” opens the door to celebrate aging as the acquisition of wisdom rather than the decline of aerobic fitness.   As Shane says, “It’s not mind over matter, it’s mind IN matter.  Finesse is stronger than force.”

What is “Kaizen”?

A Japanese translation of the Chinese “Gai Shan”. Kaizen translates to English as “continuous lifetime improvement”.  No limits.

Finesse is stronger than force.  

Here’s the Deal:  After the age of 25, we begin to lose 1% of VO2max every year.  Current endurance science, coaching and training methods focus narrowly on trying to slow the inevitable decline of aerobic capacity… while ignoring a far more powerful resource that each of us embodies, regardless of aerobic capacity.

Yes, there really is an alternative to the drudgery of “Banging your head against the aerobic wall”… day in and day out:

Kaizen Solution: Tap into and develop the most powerful resource that is infinitely available to you (and to each and every one us) regardless of your age, genetics, education or current fitness and athletic ability: Train the fitness of your mind-body connection.

Neural Fitness: Kaizen-durance is founded on the fledgling science of neural fitnessShane Eversfield has been studying and successfully applying neural fitness in his pursuit of endurance arts for four decades.  Neural fitness is the strength of your mind-body connection.  Neural fitness enables you to hack your performance potential at any age: Athletes decline with age.  Artists improve.

You can train and develop this mind-body connection as you continue to pursue aerobic fitness to…

“Maximize return on your aerobic investment… for a lifetime.”

Why “art”, rather than sport? 

Even the pursuit of combat is not called martial sports.  Shane Eversfield, Founder and C.E.W. of Kaizen-durance explains:

“To realize your highest potential, you must balance your goal-drive for a specific result at the finish line with a patient and hyper-mindful pursuit of mastery through diligent and consistent practice.  Athletes often fixate on the end goal – eyes on the prize – and stumble over obvious pitfalls, resulting in injury, illness or burn-out.  If the martial artist does this while fighting, s/he will end up injured, or worse.” 

A Deeper Look

Kaizen-durance is not “mind over matter”. It is the discovery and cultivation of mind IN matter.  Shane Eversfield, founder of Kaizen-durance calls this “kinetic intelligence”, or K.I.  He has devoted the past four decades to the study of neural fitness and its application to endurance sports.  (Scroll down to find out about his 2016 Kaizen-durance 500 ultra event.)

Caution: As a practice, Kaizen-durance is deep and systemic. It permeates well beyond athletic performance. Through your Kaizen-durance practice, you will also develop the skills to transform any form of stress in your daily life into a rich opportunity to build “life fitness”.

Every relationship, every task, every challenge in your life – from the most mundane to the most daunting – offers the opportunity to strengthen your life fitness. As you develop kaizen “navigational skills”, you will be compelled to embrace each moment as a life athlete.


Kaizen-durance Mission Statement

Kaizen-durance facilitates endurance athletes of all ages and abilities to identify, develop and engage effective “navigational skills” of mindfulness to pursue mastery and brilliance in training, competition and in everyday life experiences – from the most mundane to the most challenging.
