How can I lower my fitness age?
Consistent Zone 2 aerobic training, high-intensity intervals (HIIT), maintaining a healthy BMI, and lowering resting heart rate through cardiovascular conditioning.
Fitness Age Calculator
Fitness Age estimates your physiological and cardiorespiratory baseline compared to population norms, derived from the HUNT Fitness study algorithm.

Fitness Age = Chronological Age - Function(Resting HR, Weekly Cardio, BMI)
Quantifies cardiovascular fitness using non-exercise regression formulas calibrated against maximal oxygen uptake (VO2 Max) population distributions.
Step-by-Step Worked Example: Fitness Age Assessment
- Resting HR bonus: 54 bpm (< 55 bpm) = +4 points
- Exercise volume bonus: 180 mins/wk = +4 points
- Healthy BMI bonus: 22.8 = +3 points
- Net age reduction: 11 points × 1.2 = -7 years
Calculation Result: Fitness Age = 28 years (7 years younger than chronological age)
Clinical Nuances, Limitations & Best Practices
- Estimates cardiorespiratory fitness non-invasively; direct lab cardiopulmonary exercise testing (CPET) is required for definitive VO2 Max testing.
