JR Bourne's acting career is a lot like his physical condition—consistently in great shape.

We've gotten to know Bourne over the years through his role as Chris Argent in Teen Wolf. And now we'll see him in Somewhere Between, a new thriller coming to ABC on July 24 at 10/9 p.m. CT.

We caught up with the entertainer (and fitness enthusiast) to chat about Grouse Mountain—one of his fitness challenge recommendations in Vancouver, Canada (the show's production location)—his success using the keto diet, plus his reflection on one of the most unique training sessions he's ever experienced.
