Is anyone going to take this seriously or am I wasting my time here?
Are you a bodybuilding fan, or strictly a contributor to Wikipedia? If you knew this crowd you wouldn't ask that question, so be more patient if you really want responses that you're gonna care about. Also, not everyone that might be interested in giving you information for their entry is gonna open a thread on a bodybuilding forum labeled generically "Attention all bodybuilders." I think you might wanna change the thread title to something like, "Bodybuilding On Wikipedia," or something to that effect...something more relevant. If you want the most responses to your query, then hope a meaningful discussion gets going about it in this thread, which is the only thing that will keep it bumped, and it'll also help allow the pros more time to see it and understand the importance of it.
Actually, there's a couple of guys on here that might be interested in compiling this info as a service to the pros to give to you FOR THEM. Much like a PR person does for notable personalities in other interest groups and sports/entertainment genres.
