Why VO₂max Is the Health Metric Everyone Should Track—Not Just Athletes

In the world of endurance sports, VO₂max—the maximal rate of oxygen consumption during intense exercise—has long been used to gauge aerobic performance. But what if we told you this number isn’t just about who wins the race? It’s also one of the strongest predictors of how long and how well you’ll live. For coaches, athletes and anyone …

HIIT vs. Sprint Intervals: How to Optimize VO₂max for Endurance Athletes

Maximal oxygen uptake (VO₂max) is the cornerstone of endurance performance, and two recent studies confirm that aerobic high-intensity interval training (HIIT) is superior to sprint interval training (SIT) in improving VO₂max for both men and women. For endurance coaches and self-educated athletes, these findings offer critical insights into structuring training programs for peak performance. Key Findings From …
