Justin Hartley Instagram – Throwing back a beer in between bicep curls? More likely than you think… if you’re Justin Hartley, that is. The #ThisIsUs star is in the midst of tackling a new role on @trackercbs, one which sees him always on the go—and throwing right hooks—episode after episode. “My character is always running or jumping or climbing, fighting—a lot of fighting, turning [and] twisting,” Hartley told us about his duties as Colter Shaw. But the 47-year-old actor has spent plenty of time in the gym over the years—have you seen the man without a shirt on?—to the point that he realized how much working out was beneficial for more than just the physical side of things. “It can impact your emotional state, it can pact your stress level—it’s way more important than just physique and looking good,” he said. You can catch Hartley crushing a quick, killer arm workout (no sips between sets this time) for our latest #TrainLike episode at the link in bio.
