"however where did the comments about women that get big legs already had big fat legs to begin with come from?"
I'm generally talking about most of the women that come in for training who haven't lifted before. The fact is, most of the time their legs are big and fat (thigh skinfold well into the 30's), or there are a few that lift who also have high thigh skinfold measures and would rather not work legs than diet. If you can get you mid-thigh skinfold down to 12 mm, then take a look in the mirror and see if you still think you have big legs. If you AND others do, then you're the genetic freak.
Having said that, I do see women, one comes to mind in particular who recently joined the gym that has legs way bigger than her upper body and she is well muscled, lean and powerlifts. Another case in point is the women BB that was discussed in the "is this realistic" thread. So there are some women that develop bigs legs with strength training, juiced or not. Why genetically women can hypertrophy their legs to a greater extent than their upper body is a mystery. Doesn't seem to be this way in men, although sometimes it isn't genetic in guys since alot of them just like to train upper body because legs are too demanding, plus their easy to hide their skinny legs in baggies.
