Buffed for action?

Holy crap is that who I think it is?

Looks like someone's been seriously hitting up the gym for this upcoming Captain America movie. Wow. I almost did a double-take just to make sure those arms are real... (The feet aren't for sure, but I'm pretty sure the arms are )...

There had better be at least one shirtless scene in that movie otherwise I'm walking out (ok, maybe I won't... but they better not let this go to waste like they did with Jake G. in PoP... If you know what I mean ...)
