History
The history of calisthenics is linked to Greco-Roman gymnastics. Calisthenics originated in ancient Greece, where it was mentioned in a Persian scout report on Spartan warriors before the Battle of Thermopylae, with the Persians interpreting the odd synchronized movements as a form of dance, and thus a sign of weakness.
Disciples of Friedrich Ludwig Jahn brought their version of gymnastics to the United States, while Catherine Beecher and Dio Lewis set up physical education programs for women in the 19th Century. Organized systems of calisthenics in America took a back seat to competitive sports after the Battle of the Systems, when the states mandated physical education systems.
