Despite being in his late 60s, the veteran actor is as fit as he can be. His secret? Pilates. According to the actor, not only did Pilates help him with an injury, it has since kept him in shape. “It completely kicks my ass,” said the NCIS actor. “I had a shoulder injury that drew me to Pilates. The physical therapist I went to was all about that. They kick your ass on these machines. Pilates is all about controlling the machine, and that’s twice as hard,” he continued. He was a huge runner when he was younger but he has since switched to other workouts.
