Someone cared to downvote. So I made a random Google search and came up with this guy, who is 5'8 and 210 pounds in contest state

Which puts him at 31 BMI, so just barely in the obese category.

And this guy is clearly not your average "gym rat", he's a winner of Natural Mr. Universe, so he'll be somewhere on the very edge of the Bell curve. 99.9% gym rats will never be close in terms of lean body mass. So if they are "lumped in obese", then they truly have a lot of fat to lose.
