VO2 max estimator · Free · 90 seconds

The strongest single mortality predictor — estimate yours.

Top-quartile VO2 max carries 4× lower all-cause mortality than bottom-quartile (Mandsager et al. 2018, n=122,007). This tool produces a calibrated estimate from age, resting HR, and subjective fitness — no treadmill needed.

  • VO2 max estimate from resting HR + age + fitness
  • Mortality percentile band (Mandsager 2018 reference)
  • 12-week protocol matched to your band
  • Cross-links to VO2 biomarker + Norwegian 4x4 protocol
Measure first thing in morning, lying down, after 1 minute settling.
If you have a recent timed mile, it sharpens the estimate.
