Says he does 3,500 situps and 1,500 pushups daily. And he used to do more, something like 5,000/day.
And the man is a beast, I remember watching him play - multiple guys would try to tackle him, and after a few seconds he'd start moving the entire pile of 6 or 7 guys and push the entire group of them several yards into the end zone using his insane leg strength.
He's also fiercely agile with explosive strength. People underestimate the role of ligaments and tendons in athletics and focus too much on pure muscle strength. Yeah, this guy is a freak of nature.
