The word “calisthenics” comes from the ancient Greek words kalós, which means "beautiful”, and sthenos, meaning "strength". It is the art to control our own body “to defeat the gravity laws” and consists in several bodyweight exercises.
It dates back to the 19th century, when gymnasts brought their movement out from their gyms, but it started spreading in 2010 in America, with Hannibal for King’s YouTube videos. In Italy in 2013, people already practised calisthenics (known as street workout); so many calisthenics were born.
