National Exercise Day sits on April 18, distinct from the federally proclaimed National Physical Fitness and Sports Month in May, and its existence is attested only on holiday-listing sites. No primary documentation identifies a founder, organisation or establishing act for it.
A council in the Cold War
The federal effort began with a worry about soft recruits. In 1956, President Eisenhower created the President's Council on Youth Fitness, the first cabinet-level federal body devoted to physical fitness. It was later renamed to add "Sports," and in 2010 added "Nutrition."
For decades the council promoted fitness mostly through schools and youth testing. The science linking inactivity directly to disease was still being assembled.
