You would not be an 'ideal' macho man if you don't have muscles to show. Let's face it, woman always look first on the face, then downwards on our chest and abs, then towards the butt - almost the same way we look at them :)
It was proven that when you have a body frame of a muscle man, when you are facing behind or your face is covered, you can be mistaken with a super hunk actor even if your face is not that handsome :) So what more if you're actually handsome (we will talk about this later on other secrets), girls will actually flock to be with you, to have a feel of your muscular body.
