When is it okay for a man to hit a woman?

If there were a feminist here, she'd probably hit you.

This is true though. >_> Maybe not to female bodybuilders, but it's quite true from the crap I studied and read. Females have more 'fat' in their body, so they can produce and carry a child. Guys have more muscles, 'naturally'. Which isn't to say a female can't be stronger than a guy, just by regular circumstances, no.
