Nearly every ancient culture has evidence of stone lifting as a form of physical training for athletes and warriors. The large block of red sandstone pictured above dates to the 6th century B.C., weighs 315 lbs. and the inscription on it says: "Bybon, son of Pholos, threw this over his head with one hand." For some strange reason many people refer to this stone as an early kettlebell but I would disagree. At any rate, Bybon's stone current resides at the Archaeological Museum of Olympia in Greece.
