Not trying to start a debate, but I've read in Pumping Iron (the book), his autiobiography, a few biographys, and his encyclopedia that he was at his HEAVIEST off season at 245. But I've seen pics of him at this 'off season' weight, and he still has the abs, triceps, etc showing pretty clearly. So, it's not that hard to believe he was on stage at 230-235 and being really ripped. As for 4%, YIKES! He claimes 7-8 in all books, and talks he gives about it. You must also take into consideration his legs. His thighs at peak were 28inches. My own thighs at 6'3 are 27 1/2 inches right now, and to me are not huge by any means. And seeing as how legs are most the body weight, you can see where he was lighter. I would think if he trained them a little more, he could have easily been 15-20lbs heavier over all. Who knows...
As for all the bro's worrying about "will I look good at this weight?" "is this weight good for my height?!", don't worry about it! Bodybuilding is supposed to be a pleasureble thing. With all the worrys in life, we don't need this to turn into another one. I can tell you that size doesn't really matter personally. I felt small when I was 144.5lbs, at 175, 182, 191, 210, 220, and now at my current weight of 239 I still feel small. I have a feeling I will still feel that way at 250, 260, 270, etc. I have small joints, and naturally low body fat, a nice v taper, so I appear at least 5lbs heavier than I really am, but it all makes no difference. I am even reluctant to wear certain clothes that might show too much, because I feel there isn't anything to show. Then I see a guy my height who is about 175-190, wearing a tank top and enjoying the beautiful hot sunny day. My point? Thats when I realize there is no magic number to make you happy with your size. It's all about being happy with who you are. Sure it would be awesome to look like a Franco, Lou, Haney, Arnie, or even a Priest, Nasser, etc, but if we all keep up this mind set, we still wouldn't be happy once we got there...
