In the eyes of the majority of average men, any above average male is going to be accepted as being alpha over them.
To women, a well built man can take a couple of forms. For example, a physique like Steve Reeves or Reg Park would draw far more admiring glances from women than a Branch Warren. Some women prefer a strongman type body. Powerlifters are generally not as admired once they go the HW/SHW class unless they maintain a semblance of shape to their physiques. It's been my experience that older and/or more mature women generally prefer their man to look like a man, not Woody Allen.
I lift to stay alive and healthy. I want to look as good as I can and of course, be as strong as I can and all within reason. I am now in my 41st year of weight training.
