Powerlifter Jeff Lewis, who at 525 pounds is big even for superheavyweights, is being discussed over at Bodybuilder.com. Lewis finished second to Gary Frank at the WPO Semis. In the process he squatted a record 1202 pounds.
Some of the members over there are roughing him up pretty good. They point out that his squat is actually only 2.2 times his bodyweight. Obviously, other lifters are putting up much better differentials. They also lay into the amount of bodyfat he must be sporting.
I'd agree that it's not healthy to carry that kind of bodyweight around. But man, he is darn strong. 1202 pounds is one heck of a squat at any weight. Congratulations Jeff!
