Plutarch Caius Marcius Coriolanus 2

[1] And so Marcius, who was by nature exceedingly fond of warlike feats, began at once, from his very boyhood, to handle arms. And since he thought that adventitious weapons were of little avail to such as did not have their natural and native armour developed and prepared for service, he so practised himself in every sort of combat that he was not only nimble of foot, but had also such a weight in grapplings and wrestlings that an enemy found it hard to extricate himself. At any rate, those who from time to time contended with him in feats of courage and valour, laid the blame for their inferiority upon his strength of body, which was inflexible and shrank from no hardship.
