This young actor, who stars on ABC’s Suburgatory, has only praise for his favorite workout. “You show up, there’s a workout on the board, the clock starts—I love that you’re always competing,” Parker tells MF. “Plus you start to develop a friendship with the people you see there all week, which in L.A., can be hard to come by.” There you have it. For him, CrossFit isn’t just a workout—it’s a lifestyle. Do you agree?
