With a long shoot ahead of him, it’s important that Ben Affleck stays in Bat-shape until the end of the year. Affleck enlisted Rehan Jalali to get him bulked up leading up to Batman v Superman: Dawn of Justice, but now that he’s on set he has a new team.

According to The Hollywood Reporter, Jamie Damon, the cousin of Affleck’s BFFL Matt Damon, has been training Affleck along with Walter Norton Jr. in Los Angeles and on set of Batman v Superman: Dawn of Justice. These guys aren’t celebrity trainers either, they’re hometown friends from the Institute of Performance Fitness, based in North Reading, Mass., near Boston.

It looks like all of the hard work is paying off. Affleck was spotted a few weeks ago showing off his massive chest, as well as his 17 inch biceps (pictured below). And let’s not forget how big he looks as Batman.
