From a Wall Street Journal review by Edward Kosner headlined “‘Power Players’ Review: Sportsmen in Chief”:

From George Washington’s fabled toss of a silver-dollar-size piece of slate 250 feet across the Rappahannock River to Donald Trump’s touted 18 club championships at his 18 golf courses, athletic feats have been part of the legend of the American presidency.

By most measures, Teddy Roosevelt was the most athletically obsessed if not the most athletically gifted of America’s 45 presidents. As a youth he’d sparred with a boxing coach. In the White House, he played energetic tennis on a court right outside his office, led cowed guests on rain-sodden hikes and runs, even climbed—and tumbled into a pond—in nearby Rock Creek Park, alarming his Secret Service guardians. All that exertion won Roosevelt the nickname “Mr. Strenuousity.”
