The BioAge Index™
Welcome to The BioAge Index - the show for business owners, executives and high performers who want more energy, less drag and a younger biological trajectory.
I’m Grant Hutchby, creator of REVO and the Turnback Time system.
Our mission is simple:
Reclaim as many years of optimal life as possible, in as many people as possible, as accurately as possible.
Chronological age does not tell the full story. Your sleep, energy, stress, training, recovery and consistency are already creating a direction of travel.
The BioAge Index™ helps you understand that trajectory, find your biggest drag and track improvement over time.
It is directional, not a clinical diagnosis.
Subscribe for videos on biological age, performance, recovery, longevity science and the Turnback Time system.

Set your baseline. Find your drag. Track your trajectory. Live better, longer.

Episode 49: Most Men Over 35 Never Do This And It Speeds Up Aging
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Lifting weights is enough to stay healthy as they age. They’re wrong.
In this episode of Longevity Masters, I break down why cardiovascular conditioning and endorphins are critical for energy, resilience, and longevity.
Most men over 35 stop sprinting.
They lift. They walk. They stay busy.
But they never push their heart rate to its limit.
And the moment you stop sprinting is often the moment you start aging faster.
Cardio isn’t just about calories. It’s about VO2 max, one of the strongest predictors of lifespan and overall health.
When conditioning drops, energy drops with it.
Mood declines. Stimulants increase. Habits slip.
When endurance training returns, everything changes.
Energy rises.
Endorphins surge.
Blood sugar improves.
Focus sharpens.
In this episode, I explain:
• Why sprinting slows biological aging
• Why VO2 max predicts longevity
• Why strength without conditioning is incomplete
• The role endorphins play in energy and mood
• How endurance training improves performance in life and business
Strength builds structure.
Endurance builds resilience.
Conditioning is youth.
Watch now. Then apply it.
