Damon and a male friend headed to the Steve Tisch Sports and Fitness Center where the actor worked out on the StairMaster and then lifted light weights.
“He was definitely ripped,” Josh Morris, a senior at Tufts who was working out in the gym when he spotted Damon, tells PEOPLE. “I seemed to be the only person who noticed him, and couldn’t pass up the opportunity to say hi. He was with an older gentleman who appeared to be a friend or trainer.”
Morris even managed to sneak a quick selfie with Damon before heading out.
“Many students were saying hi, and he seemed very friendly. I assume he knew what he was getting into working out at a university gym,” Morris continues.
Dressed in a New England Patriots hat and a gray Boston Red Sox T-shirt, the actor also provided quite a thrill for the Tufts University field hockey team, posing for a photo with a few of the team members.
