Flexible Gymnastic Girl

The word derives from the Greek γυμναστική (gymnastike), fem. of γυμναστικός (gymnastikos), "fond of athletic exercises", from γυμνάσια (gymnasia), "exercise" and that from γυμνός (gymnos), "naked", because athletes exercised and competed without clothing.
History
Exercises of the ancient Greeks at first consisted of athletic feats performed by each individual according to his own notion, and were encouraged among the youth as combining amusement with exercise. These exercises were at length reduced to a system which formed a prominent feature in the state regulations for education. In fact, the period for gymnastics was equal to the time spent on art and music combined. All Greek cities had a gymnasium, a courtyard for jumping, running, and wrestling.
