FitnessNorms

Population-level reference data on physical fitness and human performance.

FitnessNorms publishes neutral charts and tables showing how fitness-related metrics vary across age, sex, and other population reference frames.

The site focuses on descriptive, non-prescriptive data derived from published studies and public datasets. No personalised recommendations or coaching advice are provided.

Initial reference pages will cover metrics such as aerobic capacity, strength, and energy expenditure, presented using simple, reproducible transformations.
