Guys opinions of models, girls opinions of muscles. GREAT QUESTION?

okay, this is a very interesting question for me. I was looking through a guys magazine the other day and I saw all of these ads for guys to gain muscle. I was thinking to myself that most of the guys looked better in the before picture. I then realized that when girls look at vogue, we see stick thin models and idolize them, wanting to be as thin. Do guys think the models are too thin? truthfully? Do girls see what I'm saying? I don't tihnk too many muscles are attractive. I'm interested to see what everyone says. DONT BE SHY!
