Why Your VO2 Max Matters More Than Your Step Count

9 to 5 Wellness

About

If you could track one number that shows how long and how well you'll live, it would be your VO2 max. In this episode of the 9 to 5 Wellness podcast, I'm diving into VO2 Max: what it is, why researchers treat it as a longevity biomarker, and how busy professionals can raise it.

Many of my clients and patients put it this way: "I don't feel old, and I want to stay this way." If that sounds like you, start here.

In this episode, you'll learn:

    What VO2 max is, and why it's also called your aerobic capacityHow your heart, lungs, circulatory system and muscles work together to turn oxygen into ATP, your body's energy currencyThe study of more than 122,000 patients that linked a higher VO2 max to a lower risk of death from all causes, not just heart diseaseWhat counts as a "good" VO2 max for your age, sex, fitness level and altitudeWhere to get tested: university labs (often free), cardiopulmonary exercise testing (CPET) or a smartwatch estimateHer top 3 strategies and 2 favorite workouts for improving aerobic capacity
