What's puzzling is that bodybuilder physiques aren't even attractive to most people. I don't mean physically fit and showing some muscle, I mean the extremes of Arnold and even more "built" guys. When you talk to normal people, they don't find it attractive. The people who universally find the bodybuilder physique attractive are other bodybuilders! It's a very "niche" look.
And it's well-known it's not a physique that correlates with actual physical strength or agility. It's just for show. Actual physical fitness doesn't look like that, and even bodybuilders admit this.
