So... You're saying superheroes don't know how to use their muscles?<br/><br/>Besides, how much effort does it take to know how to use muscles? I think many of us have learned how to move or lift things already, and having muscles certainly makes that easier. Are you suggesting that muscles are worthless if you don't know how to do kung fu or something like that? Because that's actually not true either. You don't want abs and big biceps if you do martial arts. Bruce Lee was actually criticized in the martial arts community for working on 'vanity muscles'.
