I'm holistic kinda guy...something about the whole appearance at a glance gives a lot away. Facial features and expression, build, posture, deportment, dress sense, hair, social setting. Gives me a good idea of the person she is without even saying a word.
There is always physical attraction before anyting else, even if they have great personality. Some don't agree but when they fall for someone they say they didn't find attractive, I wonder then how did they fall for that person? They must have found them in some way attractive, but perhaps didn't acknowledge it at first.
It's not shallow, just a million years of natural selection.
BTW, the bodybuilder is grotesque.
