Far more than 200. A thick and muscular woman (who's not fat) can weigh 200 at around 5'8" to 5'10". I'd say probably at least 230, and 250 isn't out of the question, depending on just how thick and muscular she is.
Like all things, though, real research is your ally. Call a gym and ask where female body builders train in your area. Call that gym, tell them you're a writer who wants to get a detail right, and ask if they have anyone who can talk to you about how much a large, thick woman weighs.
Also worth a mention: Does your reader need to know this number? Why?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
