Q. Which American President Rode a Mechanical Horse in the White House?

A. Strange but true that Calvin Coolidge received a gift of a mechanical horse when he was in the White House. He often rode it dressed as a cowboy or sometimes in his underwear. It was a central feature of his exercise regime.

I guess this may have made President Coolidge one of the original rhinestone cowboys? Presidents today of course work out extensively and use a variety of equipment. As there were fewer indoor exercise machines in the 1920s, I guess President Coolidge's choice is not really that strange.

I can just imagine "Silent" Cal whooping it up on the saddle...
