Etymology

from Greek kalos "beautiful" and sthenos "strength"

Word Origin
The benefits that exercise can have for both strength and looks are suggested by the origin of the word calisthenics. Calisthenics was made by joining the Greek kalos, meaning "beautiful," and sthenos, meaning "strength." The word was originally used to refer to exercises done by young women, but it later gained the more general meaning that we now know.
