Henry Cavill has been in peak shape for years, but he's somehow managed to get fitter. If anyone saw Cavill's most recent—and terrible—release, The Man from U.N.C.L.E., then you know that Cavill's arms have been trying to break free of his shirts. This revolt of his muscles is thanks to the upcoming March blockbuster Batman v Superman, where Cavill will be gracing screens again as Superman and facing off against a very muscular Ben Affleck

Until theaters display the larger-than-life images of Cavill and Affleck fighting in very tight outfits, there's this photo to tide everyone over. It marks Cavill's first shirtless Instagram, and though his relatively new account has been decent so far, this pic certainly ups the ante.
