Someone on another board asked this and alot of the women said ‘yes’ they noticed and they listed what parts they noticed in order. It tended to go something like chest, shoulders/traps, biceps, in that order.
However this was a fitness board, filled with insecure, narcissistic people who use performance enhancing drugs. What about women who aren’t into that lifestyle, do you notice or care if a man is muscular? Does it matter if he is or isn’t rail thin while muscular? What parts do you notice or find attractive?
I have heard from reading about the biology of attraction that a V shaped torso is to women what an hourglass torso is to men, the common sign of health and fertility. If so that explains why shoulders was no. 1 with women on that other site and chest came in 2nd.
