The issue here is real-world practicality for the straight male.
Muscle
can be used to get women, not just to get big.
Females love the thin but muscular look; they shun the bulky square look we often strive for in bodybuilding.
For example, Anibal would pull massive amounts of hos:
Thickness isn't an advantage, but muscle is. What this means to us is that in gaining muscle to attract women, there's a point of diminishing returns. Most women do like muscles, but don't like monsters. We should look practical and not square. To the female's subconscious perception, a considerable amount of muscle
that doesn't appear to hinder one's speed and flexibility, combined with a low level of bodyfat, equals functional advantage in the interest of survival. This means a rare, advantageous male to the female.
