4. VO2 Max: #1 Predictor of Longevity and Healthspan

 In this episode of MD Longevity Lab, we dive into VO2 max—widely regarded as the single best predictor of longevity. It’s a modifiable metric that speaks volumes about your cardiovascular fitness and future healthspan. But before we get into the science, we kick things off with a classic marital squabble (because, of course, nothing says "longevity" like a debate with your spouse about semantics).

Whether you're a weekend warrior, trying to improve your health, or someone just trying to keep up with your kids, this episode will break down:

• What VO2 max really is
  
• Why it matters more than you think
  
• How you can test it and improve it
  
• The longevity benefits of simply moving more
  
• Our own approach to building VO2 max into a busy life with kids, careers, and chaos
  

Key Takeaways:
✅ VO2 max is not just for elite athletes—it’s a metric anyone can track and improve
✅ Even modest improvements can lead to dramatic reductions in mortality risk
✅ Zone 2 training, HIIT, and daily movement matter
✅ It’s never too late to start

Real Talk Segment:
We share the behind-the-scenes reality of getting on the same page as a couple when one of us thinks we're "fit enough" and the other disagrees—spoiler: guess who wins?
