The United States Navy “V-Five Association” is legendary. This WWII physical training produced some of the US Navy’s finest pilots and men including former President Gerald Ford and some of NASA’s Apollo astronauts.
The V-Five published about a dozen manuals on various physical topics including mass calisthenics, track & field, gymnastics, and many other sports.
This video specifically addresses the history of football in the US Navy.
