Walter Camp (1859 – 1925) was an American football player, coach, and sports writer known as the “Father of American Football”. Among his gridiron inventions, are the line of scrimmage and the system of downs.
Camp was believed in keeping in shape through simple exercises. As an adviser to the United States military during World War I he devised a program to help soldiers and sailors become more physically fit called the “daily dozen set-up” comprised of twelve very simple exercises. The exercises in the original Daily Dozen involved hands, grind, crawl, wave, hips, grate, curl, weave, head, grasp, crouch, and wing and took about eight minutes. Camp wrote a book explaining the exercises and in the 1920s newspapers and magazines generically used the term “Daily Dozen” to refer to exercise.Starting in 1921 with the Musical Health Builder record sets, Camp began offering morning setting-up exercises to a commercial market.
This manual accompanied the recordings. The design was fairly impressive as info graphics during the 1920s.
