The 50-year-old actor, who stars on the DirecTV series Kingdom, opened up about his boxing workouts and keeping his body in shape.
“There’s no better workout than boxing,” Frank said. “Short, fast bursts of energy, constant acceleration. You’re burning deep, deep fat cells and using everything you store. There’s never an excuse to miss a workout. I play an MMA coach on [DirecTV's] Kingdom, so I work in a gym! And even if I’m not in the gym, I can do a 45-minute routine with dumbbells, a jump rope, and shadowboxing that burns a ton of calories.”
“I stick to a paleo-centric diet—wild-caught fish, organic chicken, no grains, rice, or oats. As a wrestler, I was always cutting weight, so I was never really a foodie. My one indulgence is wine,” Frank added.
