You’d think that appearing on the silver screen in a skin-tight outfit to portray no less an iconic character than Superman would prove incentive enough to hit the gym, but Man of Steel star Henry Cavill reveals that he was spurred on even further upon seeing the killer shape that his Batman v. Superman co-star Ben Affleck had achieved in order to play the Dark Knight.

In an interview today with Good Morning America, Cavill admits that he “worked a little harder on this [movie]. I got a little bigger,”; and credits Affleck’s buff Bat-bod with inspiring him to add bulk.

“When you see Ben on set and everything and he’s in good shape, it makes you want to go back to the gym that morning and work a little harder,”; said Cavill.

That being said, Cavill is a firm believer that his character would clearly prevail in a Batman-vs.-Superman battle.
