How It’s Calculated

Inputs and windows

  • WHOOP recovery window: 90 days
  • Garmin running window: 84 days
  • Workout consistency: 48.9% of days active
  • Average pace: N/A

Weighting model

  • HRV score (30%): higher is better vs age norms
  • Resting HR score (25%): lower is better vs age norms
  • Workout consistency (20%): frequent training boosts score
  • Cardio volume (15%): more running miles improves score
  • WHOOP recovery quality (10%): recovery trend stability

Fitness Age vs Actual Age

With an actual age in the 40s, current recovery and cardio trends indicate a physiological profile that trends 2 years older than chronological age. This estimate updates as WHOOP and Garmin data evolve.
