Not a bodybuilder, but I did go to the same gym(s) as two world record holding benchers.
One was Dave Waterman. He was shorter than me (I'm 5'5"), 198lbs and benched over 600lbs. Another guy who went to the same gym (Body America, which closed down and he now goes to Powerhouse) was Jim Kilts. Also benched over 600, but I think he weighed around 180 something.
Dave looked more like a bodybuilder. He looked as wide as he was tall, and was shredded. Jim is big as well, but it's not as blatently obvious as Dave was. I don't think either of them were competitive in squats or deads (though I'm not sure), but their benches were still incredible, especially for their body weights.
They were awesome to watch working out, but I would try not to bother them as I didn't want to be that anoying kid always asking questions.
They both gave me a lot of motivation to keep doing what I'm doing.
