Young Blonde Girl With Undress Her Black Camisole And Knickers And Doing Flexible Gymnastic Exercises In The Bedroom

Etymology
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.
