OK, so I'm going ot contest ExistentialDisorders comment to a degree. Depends on how much "doesn't move much" equals. While I can agree it's not enormous, it's all moving. Hips will twist a little as well as stomach. The only reason I mention this nitpick is I've recently seen a lot of pics in the galleries that have enormous twists in the chest with none in the abs or hip. Looks painful.
