Matthew Daddario on 'Shadowhunters' Work Out: 'It Was Endless!'

Matthew Daddario stops by the AOL Build series to talk up Shadowhunters on Monday morning (January 18) in New York City.

“It was endless. You have to watch your food intake and you have to run and you have to work out,” the 28-year-old actor shared with HuffPo Live later on.

Matthew continued, “When I first started, I was running the first thing in the morning, and running when I got home…running myself ragid there. I was eating a diet mostly of chicken and maybe some vegetables. It wasn’t very fun, to be honest, but eventually, you do start to get obsessed with it and enjoy it.”

“By the end, we were all fitness freaks, which was good because Shadowhunters are supposed to be in very, very good shape,” he said.
