A hundred years ago this month, the June 1922 issue of Talking Machine World carried this advice for phonograph dealers worried about a summertime slump in sales. Their lifesaver would be the “Health Builder” records featuring the Daily Dozen exercises of Walter Camp.

Camp had worked as an adviser to the U.S. military during World War I and came up with a physical fitness regimen for servicemen. This became the “Daily Dozen,” a series of twelve simple exercises to get a running start on the serious work of the day. The Daily Dozen were featured in books and articles, and starting in 1921, in this series of phonograph records. So the dealer could sell not only the records, but also the phonographs to coach customers on their fitness regimen.

Camp’s company could supply the literature and cut-outs, and suggested that the dealer run demonstrations. They could use an athletic member of the sales force, or a young husky from the neighborhood.
