“If I’ve had an indulgent night, I try to make up for it as soon as possible the next day… I’ll go work it out. I have a trainer in West Hollywood, Gregg Miele at Heart and Hustle gym,” he said three years ago. “When I was getting in shape for the show (DirecTV’s Kingdom), I was doing three sessions a day: one fight-training with Kingdom‘s coach, Joe “Daddy” Stephenson, and two strength-building with Gregg. Each workout focused on a different region of the body—upper body, core, or legs—and we’d do a circuit of six different moves for one area. Lifting a lot of weights, really trying to break the muscles down.”

The gym is a popular spot for celebs – Ryan SeacrestCalvin Harris, and Olivia Culpo all frequent the spot. While Jonas doesn’t often show off his body on his own Instagram page, he’s posted a few that show off his buff arms in recent months.

My favorite part of the workout is always the protein shake afterwards.
