I want the woman to be more muscular, and I want her to win against genuine resistant, but subject to that I want the guy to be a normal specimen.
A 180lb fbb should certainly be able to overpower a 180lb guy who is reasonably fit but nowhere near her condition. Even a 200lb guy.
She wouldn't be able to casually lift him and spin him around like the puny men if that's what you want, but she could certainly manhandle him and come out on top.
