Pretty sure big Lou could bench over 500. Lou was massive, you just don't get that way without moving some heavy Iron.
Wes- I can understand judging by your build how you could see it the other way. I myself benched 445 for a single, my best ever. I did this at 225 pounds bw, I have long arms like Lou and, Lou has much more mass than I, Lou had to be strong.
i agree. the guy was 6'6"..and thick across the pecs.
He got to 315 in contest shape.
i cant see any reason why he wouldnt have benched high 500s for a single..if he chose to.
heck, 400 for reps seems very weak for a 330+ lb guy to me.
either way, he was big enough to be able to do, or he was just not mechanically configured for good benching so didnt do it.
if it was based on size alone, then you'd think he could do it.
