You'll find them in indies and other promotions. I don't really follow it too much but there is a faily big female wrestling promotion which I'm sure will have some built wrestlers.
I think if they refer to them as a diva, or a knockout, they aren't going to be bodybuilders. Beth Phoenix looks stacked though, as well as pretty.
Chyna had muscle, and out of 10 she was possibly a 3 at her peak and when she was being carried, if the normal WWE divas are a 1.
