My ex was a body builder, steroid user and at the time, the largest dealer in the west coast (quite a distinction, eh?)- until he went to prison, of course.
Yep. I wasn't always a mild mannered 'net jocky. I have a past.
Anyway, yes a lot do have body dysmorphic disorder; they don't think they are big and do anything they can to get bigger.
The ones who are super large for competition don't look quite this distorted because the contests require symmetry and being very cut and these guys don't have it, they are just trying to get big because they don't think they are.
But to be fair/play devil's advocate- whatever, I'm sure there are an equal amount of people who look at over weight people and underweight people and say just as judgemental things as folks are saying about these dudes.
I have to say that because for years and yers, I hung out with all kinds of body builders; the natural competitors (yes, they get tested), the "other" ones who get all the glory (and no they don't get tested and if a contest announces they are testing, the contestants typically withdraw from the contest), people who took steroids but never wanted to compete, they just liked the way they looked and then of course the BDD ones and for the most part, they were all nice, friendly, funny, decent people. Some just got carried away and some didn't know they got carried away.
