Etymology of gym

Gym is short for the Greek word gymnos which means naked.

Gym is also a short form for the word gymnasium which, in Greek, means place to be naked.

The word gymnasium was used in ancient Greece, meaning a locality for the education of young men, including physical education (exercise) which was customarily performed naked, as well as bathing, and studies (most gymnasia had libraries that were often used after relaxing in the baths).

Physical education was considered at least as important as learning.
