It triggers me more than it should too, after all it's some superlazy guys coping and inferiority complex. Working out does not stop you from reading books, drawing comics etc. And the guy who works out will also eat healthy, so no saggy body for him.
A huge problem is that people are unable to see inside of them, the healthy guy will look beautiful inside while the comic drawer and other unhealthy people will have a terrible body both inside and out
