Of all the celebrities who have trouble keeping their muscles contained, Chris Evans might be our favorite. It all started when he got superhuge and superhot for Captain America, and since then, he's had us beside ourselves at every turn. He's taken his rippling muscles to Comic-Con, he was easily the best part of this year's People's Choice Awards, and of course, he's been captivating us in all the Marvel movies he appears in. Since we can never really focus on anything else, we're launching a full-scale investigation into his practically trademarked physique and all the times it was desperately trying to escape his clothes. If you finish and find yourself wanting more, fear not — we've inspected Joe Manganiello's beautiful biceps as well.
