The One Number That Tells You How Long You’ll Live Well

The Ride Back: One CEO’s Journey from Burn Out to Leading Better

Dan Hurdle spent 30 years climbing the executive ladder. Boardrooms, big decisions, bigger pressure. By the time he stepped into his final CEO role, he had mastered the art of leading organizations — but along the way his health had quietly slipped off the agenda, especially during his final executive role.

Stress had taken over. His body was paying the price. He didn’t know if he would make it.

That’s when we got to work.

Nothing dramatic. Nothing overnight.

We built a sustainable leadership practice centered around physical health, recovery, and performance. We dialed in a strength training routine, introduced mindfulness practices to improve stress resilience, and got him back to one thing he had always loved — mountain biking.

Slowly, the conditioning came back.

So did the clarity.
So did the energy.
So did the capacity to lead under pressure.

The stress hadn’t disappeared — but the way he moved through it physically and psychologically improved day by day.

His investment in his own wellbeing ultimately improved how he showed up for his people. Today, Dan doesn’t just live this philosophy — he coaches it. He went on to become a Duke-trained human performance coach and now helps other leaders rebuild sustainable performance from the inside out.

Here’s what I’ve learned working with leaders like Dan:

The busiest, highest-performing leaders are often the last ones to invest in their own health.

But physical health, recovery, and VO₂ Max may be some of the most overlooked leadership longevity strategies available to executives today.

If you’re carrying a heavy load right now, this article is for you.

The One Number Most Leaders Never Track

Your body has an engine efficiency score. Most people never check it.

Of all the metrics in medicine, few predict how long — and how well — you live as powerfully as VO₂ Max.

VO₂ Max is one of the strongest indicators of cardiovascular fitness, cognitive resilience, stress tolerance, and long-term healthspan. For executives and high-performing professionals, it may also be one of the most overlooked leadership longevity strategies available.

Leading longevity experts are direct:

“VO₂ Max is more strongly associated with reduced mortality risk than nearly any other measurable fitness marker.”¹

We obsess over cholesterol, weight, and BMI. But decades of research point toward cardiorespiratory fitness as one of the strongest predictors of all-cause mortality and long-term performance capacity.

What is VO₂ Max?

Think of your body like a high-performance engine.

VO₂ Max measures how efficiently your heart, lungs, blood vessels, and muscles process oxygen during physical effort. It’s measured in milliliters of oxygen per kilogram of bodyweight per minute.

The higher the number, the greater your aerobic capacity and cardiovascular efficiency.

But this metric represents more than fitness.

VO₂ Max reflects how efficiently your body produces and sustains energy under stress and demand. That’s one reason it has become such an important marker in conversations around human performance for leaders and sustainable leadership practices.

It’s an integrated score of:

• heart function
• lung capacity
• blood vessel efficiency
• muscular endurance
• mitochondrial health

Which is exactly why it predicts so much.

Why Leadership Longevity Depends on Physical Capacity

The Two Pillars of Leadership Longevity

Among all leadership longevity strategies, maintaining VO₂ Max and strength may have the greatest long-term impact on energy, resilience, and healthspan.

1. VO₂ Max — The Aerobic Engine

VO₂ Max predicts:

• cardiovascular health
• endurance
• recovery capacity
• energy sustainability
• all-cause mortality

Higher levels of aerobic fitness are associated with better resilience and greater physical capacity under stress.

For executives and high-performing professionals, this directly impacts sustainable performance over time.

2. Strength — The Physical Foundation

Muscle mass and strength protect against:

• frailty
• injury
• metabolic disease
• physical decline
• loss of independence later in life

Research from the PURE study found that grip strength alone may predict hospitalization and mortality risk more effectively than several traditional clinical markers.²

Strength also supports posture, movement efficiency, resilience, and long-term physical reserve.

Together, strength and VO₂ Max create what longevity experts often call “physical reserve” — the buffer between your current capacity and the minimum needed to function well under stress.

The wider that reserve, the greater your resilience.

The Marginal Decade

Longevity experts often describe the “marginal decade” — the final 10 years of life.

During this stage, VO₂ Max and strength often determine whether someone remains independent, active, and engaged or becomes increasingly dependent on others.

The remarkable insight is this:

That decade is heavily shaped by the habits built decades earlier.

The time to build leadership longevity is not after burnout.
It’s now.

Why Leaders Should Pay Attention to VO₂ Max

Sustainable Performance Requires Physical Capacity

Leadership is a long game.

Executives are expected to make high-stakes decisions, manage uncertainty, lead teams, and maintain emotional composure for years — often decades.

That level of output requires physical systems that can sustain stress and recover efficiently.

VO₂ Max is one measurable indicator of that capacity.

Stress Resilience Is Physical, Not Just Mental

Stress management is often framed psychologically, but resilience is deeply physiological.

Aerobic fitness improves the body’s ability to recover from physical and psychological stressors. Leaders with greater cardiovascular fitness often tolerate pressure more effectively and recover more efficiently between demands.

Your Peak Career Years Coincide With Physical Decline

Many leaders step into their most consequential roles precisely when fitness naturally begins to decline.

That’s why proactive investment in health, movement, recovery, and sustainable leadership habits matters so much.

Sustainable Leadership Practices Start Small

One of the biggest misconceptions around health and performance is that transformation requires a complete life overhaul. The most effective leadership longevity strategies are often the simplest and most sustainable.

It usually doesn’t.

Dan didn’t rebuild his health overnight.

It happened through:

• consistent strength training
• regular movement
• mindfulness practices
• gradual aerobic conditioning
• recovery habits
• getting back to activities he genuinely enjoyed

One ride at a time.
One habit at a time.
One decision at a time.

Research shows VO₂ Max is highly trainable, with measurable improvements in aerobic fitness often occurring within as little as 6–8 weeks of consistent training.³

That’s what sustainable leadership practices look like in real life.

Leadership Performance Is a Long Game

Investing in your VO₂ Max won’t just improve fitness.

It can improve:

• resilience
• energy management
• recovery capacity
• long-term wellbeing
• physical reserve
• quality of life

In many ways, leadership longevity and physical longevity are deeply connected.

Healthy leaders tend to sustain impact longer, recover better under pressure, and maintain greater capacity over time.

Just ask Dan Hurdle.

My husband and I are both executives and investing in our quality and length of life means doing things that improve our strength AND VO2 Max.
