Expert Positions
The Verdict
All 5 experts agree VO2 max is one of the strongest predictors of all-cause mortality. Patrick frames moving from low to elite fitness as potentially adding ~5 years and outweighing the risk of smoking or diabetes, and Huberman ranks cardiorespiratory fitness above any supplement for longevity. It declines ~10% per decade if you don't train it, but rigorous training can roughly halve that rate. The consensus protocol: a Zone 2 aerobic base plus 1-2 high-intensity interval sessions a week — the Norwegian 4x4 is the most-cited.
Where They Disagree
Zone 2 volume vs HIIT efficiency: Attia argues most people should prioritize a large Zone 2 base (80/20), while Patrick — via Dr. Martin Gibala — emphasizes that short vigorous intervals can match VO2 max gains in far less time, a stronger time-efficiency case for leaning into HIIT.
How much high intensity: prescriptions range from Hyman's 20-30 min of HIIT twice weekly to Johnson's 90-150 min/week in Zone 5, which makes direct comparison difficult.
