Portrait of Archibald Hill

Why Archie?

Named after Archibald Hill

Archie is named after Archibald Hill, the physiologist who discovered VO2 max and won a Nobel Prize in 1922. His work founded modern exercise science.

Real measurement and real physiology, not generic formulas. Those are the standards we hold ourselves to, and what we built Archie on.
