Episode Overview
In this Longevity Shortcut episode, we dive into one of the most underrated (and under-measured) metrics of health: oxygen efficiency. Our guest, Shane Stubbs, author of The Perfect Health Lesson, has spent decades researching how oxygen efficiency can dramatically lower the risk of chronic diseases and optimize overall health.
Oxygen Efficiency vs. VO₂ Max
VO₂ Max: Measures the maximum amount of oxygen your body can use during intense physical activity.
Oxygen Efficiency: Shows how effectively your body delivers and uses oxygen at the cellular level. This impacts heart health, recovery speed, resilience, and disease risk.
Shane’s Impressive Score
At 59 years old, Shane’s absolute VO₂ Max is 4.75 liters per minute—a score typically seen in fit young men in their 20s.
This places him in the top 1–2% for his age group, proving that with the right training, you can dramatically surpass typical “age-based” health expectations.
AQ Points & Strategic Training
Activity Quotient (AQ) Points: A simple tracking system to ensure you’re hitting the right heart rate zones.
Training Protocol: Short, consistent sessions at 80–90% of max heart rate, about 2–3 times per week.
Improvements often show up within 8–12 weeks, affecting not just fitness but also blood markers and overall health.
Why It Matters
Low VO₂ Max is an early warning sign for heart disease, stroke, type 2 diabetes, and even dementia.
Scientific studies link high VO₂ Max to a 30% lower risk of heart disease and a 54% lower risk of type 2 diabetes.
The Perfect Health Lesson Framework
Shane’s method is not a diet or workout plan—it's a health transformation framework that combines daily habits, AQ Points, and targeted exercise.
The goal is to reprogram your body’s oxygen system, enhance resilience, and potentially slow down—or even reverse—biological aging.
Track Your AQ Points
Use any simple system (like Shane’s) to measure whether you’re consistently triggering the right intensity in your workouts.
Estimate Your VO₂ Max
Use a smartwatch, a beep test, or software like Shane’s Health Impact Softw

Are You A Charlotte?
In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
