I'm stealing this from Paleo hacks ( http://paleohacks.com/questions/2440...eoHacks.com%29 ):

Legend was that this ancient strong-man [Milo of Croton, the ancient Greek wrestler] had won at least six Olympic championships and that he trained over the four years leading up to the games by picking up and carrying a calf. As the animal matured, Milo was tasked with carrying a heavier and heavier load. Milo’s progressive weight-training program would culminate with him carrying the full grown bull into the Olympic stadium, carrying it the full length of the field where he would then kill, butcher, roast and eat his training medium.

Greek O... I mean, Grok On!
