What if one metric could predict how long — and how well — you live?

In this episode, Dr. Elie sits down with Dr. Andrew Sellars, physiologist and Co-founder of VO₂ Master, to decode one of the most powerful markers of longevity, resilience, and performance: VO₂ max.

Dr. Sellars has pioneered the world’s first truly portable, lab-grade metabolic analyzer — a technology that’s reshaping how athletes, clinicians, and wellness centers around the world measure the body’s internal performance in real time. Today, we break down why VO₂ max is far more than a fitness number — it’s a window into your mitochondrial health, metabolic flexibility, and biological age.

From elite athletes to everyday individuals, from hot Gulf climates to high-performance labs, we explore how oxygen efficiency sits at the core of human potential.

We discuss:

• What VO₂ max really measures, and why it’s among the strongest predictors of healthspan and longevity

• The evolution from traditional lab testing to real-world portable analysis

• How mitochondrial efficiency and oxygen utilization shape resilience and aging

• What Dr. Sellars has learned from testing thousands of athletes and users worldwide

• Why early metabolic diagnostics can prevent chronic decline before symptoms appear

• How heat, humidity, and regional environments affect metabolic demand especially in the Gulf

• The technology revolution behind VO₂ Master: portability, wearables, cloud data, and AI

• Isocapnic breathing: what it is, how it works, and why it enhances recovery and performance

• Practical steps to safely improve VO₂ max and track meaningful progress at any age

• Dr. Sellars’ one essential message for anyone seeking to live longer, stronger, and sharper

A deep dive into the future of metabolic health. where data, breath, and physiology meet to define the next era of human performance.
