According to the Oxford English Dictionary, the exercise was named in the 1930s for American physiologist Royal H. Burpee, who developed the Burpee test. He earned a PhD in Applied Physiology from Columbia University in 1940 and created the "Burpee" exercise as part of his PhD thesis as a quick and simple way to assess fitness. The exercise was popularized when the United States Armed Services adopted it as a way to assess the fitness level of recruits when the US entered WWII. Consisting of a series of the exercises performed in rapid succession, the test was meant to be a quick measure of agility, coordination and strength.
