I second powerifterjay's opinion. No way this guy is curling twice his bodyweight. I know there are some strong SOB's on this board, but can anyone here even curl his own bodywieght? I can't, not even close.
And I also agree with Jay that these numbers do not add up. I can rep out on dips with 100lbs attached, but I cannot even get close to getting a 500 lb bent row off the floor. And who can bent row 100lbs more than they bench?
Also, this guy is 2 inches taller than me and 50 lbs lighter, and I am by no means the thickest guy around. But you are telling us someone this skinny is doing these things?
What do his arms, chest and legs measure?
