Bodybuilding is a pageant show as far as I am concerned, or the judges themselves. They could care less how you attain the physique you do, you could be mowin lawns like ronnie does for all the Judges care, and be growin like weed like Kamali in the offseason and show up on stage. As far as athleticism goes, the picture that Intenseone pretty much shows how "athletic" these "athletes" are.
If bodybuilding is a sport, then why aren't modeling, spelling B's, Dominoes, etc considered sports? All are forms of entertainment, and require certain skills.
