Estimate your biological fitness age from key health metrics.
Fitness age is an estimate of your cardiovascular health relative to your chronological age. A lower fitness age is associated with longer lifespan and reduced risk of chronic disease. Research from the Norwegian University of Science and Technology shows VO2 max is the strongest predictor of fitness age.
This simplified estimator uses resting heart rate, exercise frequency, and BMI as proxies. For a more precise fitness age, a VO2 max test with a sports medicine professional is recommended.
