For boys'and girls'gymnastics in schools.The first recorded gymnasiums date back to over 3000 years ago in ancient Persia, where they were known as zurkhaneh, areas that encouraged physical fitness. The larger Roman Baths often had attached fitness facilities, the baths themselves sometimes being decorated with mosaics of local champions of sport.Today, gymnasia are commonplace in the United States. They are in virtually all U.S. colleges and high schools, as well as almost all middle schools and elementary schools. These facilities are used for physical education, intramural sports, and school gatherings. The number of gyms in the U.S. has more than doubled since the late 1980s.[11]
