One number predicts your 10-year mortality risk better than cholesterol, blood pressure, or BMI...
VO2 max — the maximum rate of oxygen your body can utilize during intense exercise — is the single strongest predictor of all-cause mortality in the published literature. A low VO2 max (below 25 ml/kg/min) is associated with a 5x higher mortality risk compared to elite fitness (above 54 ml/kg/min). Moving from 'low' to 'below average' fitness is associated with a 50% reduction in mortality risk — a larger benefit than quitting smoking.
VO2 max declines ~10% per decade after 30 without training. Zone 2 cardio (conversational pace, 60–70% max HR) for 150–180 minutes per week is the most evidence-based intervention for improving it.
VO2 max: the volume of oxygen your body uses at maximum effort.
It is the single strongest predictor of all-cause mortality in the medical literature.
Low VO2 max is five times the mortality risk of elite fitness.
Moving from low to below-average fitness cuts mortality risk by 50% — larger than quitting smoking.
It declines 10% per decade after 30 without training.
The intervention: Zone 2 cardio.
Conversational pace.
60-70% max heart rate.
150-180 minutes per week.
That's the longevity prescription.
Not supplements.
Not biohacks.
Aerobic base..
Check your estimated VO2 max in your fitness tracker. Then commit to 3x 45-minute Zone 2 sessions per week for 8 weeks. The longevity data is unambiguous.
