The arms and back is a different deal and generally just get bigger, but you can't really see much of some muscles if they're covered up with fat.
I was actually coming from a muscle-building perspective moreso than strict body-building. I didn't want to put this in powerlifting as our discussions have been about muscle-building.
They have slightly different shapes, although they all carry varying amounts of belly. It's not that they don't have chests, it's that their chest are very under-developed in comparison to other muscle groups.
