Well, you know beauty's in the eye of the beholder. Some people just don't like muscle - even a small amount - when that muscle is on a woman.
I had a guy come up to me in the gym not too long ago and tell me he wished his girlfriend could see me because she doesn't think muscle can be attractive and sexy. The problem is even if she saw me, she probably wouldn't change her mind. This seems to be a pretty black and white area, unfortunately.
I was talking with a male co-worker (who lifts) about going to the Arnold and mentioned Timea was competing. I flip to a picture of her I'd just seen in his Men's Health, and he says "she's too muscular - you can see her triceps". I personally think Timea has an incredible physique and would love to have her fullness of muscle. Like I said, you either like muscle or you don't. If you don't like the look, you'll never be incented to lift.
