The ancient Greeks placed a high value on both physical and mental fitness. Each important city in Greece had a public area set aside in which young men would gather to exercise, compete in sports, and receive training in philosophy, music, and literature.

Living in a warm climate and not wanting to be encumbered in their activities by unnecessary clothing, the Greeks would typically do their exercising without wearing any apparel.

3. Etymology: the term given for the exercise area was gymnasion,; literally, "school for unclothed exercise"; from the Greek verb gymnazein, "to exercise with no clothing"; which is a derivative of the adjective gymnos, "unclothed".

The Greek gymnasion, became the Latin gymnasium, which was used in two distinct senses to mean both "an exercise ground" and "a public school".
