This week, Entertainment Weekly features Chris Evans on their cover from his upcoming movie Captain America.
I don't know much about the Captain America character other than he carries around an indestructible shield and fights Nazis. According to his comic lore, "Weakling Everyman Steve Rogers ingests the Super-Soldier serum and gains incredible strength and agility."
Every man does not look like that.
I think "Super-Soldier serum" is now known as Steroids. The results are evident when viewing the variety of ox-shouldered guys at the gym whose ginormous arm trunks haven't casually relaxed against (or touched) their hips since their "treatments" began.
Now that looks natural.
