A Damon helped Ben Affleck get the big muscles he’s attained for his role in Batman vs. Superman: Dawn of Justice.
Make that Jamie Damon, one of Affleck BFF Matt Damon‘s first cousins. Jamie is among a group of trainers, including Affleck’s main sweat sergeant, Walter Norton Jr., who have been training the actor both in L.A. and on set for the superhero part.
The crew aren’t Hollywood trainers either, but hometown talent from the Institute of Performance Fitness, based in North Reading, Mass., near Boston.
Matt calls Jamie “a stud of a trainer.”
