women body builders question

[Guest guest]

We took a break from the seemingly endless beach volleyball this evening and peeked in on a show about women body builders. Wow are those women built! Without meaning to insult anyone that appreciates that look, DH said "They look like male bodies with female heads on them." Some still had breasts which I suspect are fake. Anyway... DH and I were wondering how women can actually bulk up that big?? I didn't think we had enough male hormones for it to happen. Are they taking steroids or doing seriously heavy weights seriously often? I don't want to look anything like that but I wouldn't mind being more "cut" (very toned looking but not for the term "muscular" to come to people's minds looking at me). I'm not concerned about looking that way either, am mostly just curious as to how it happens. Anyone have any insights?
