In 1997, Arnold underwent open heart surgery to repair a defective valve, and doctors cautioned him to reduce the intensity of his training going forward. In 2003, he needed shoulder surgery after an accident on the set of Terminator 3—the shoulder was operated on again in 2012.

As governor of California from 2003–2011, Arnold relied more on cardio, for heart health and to burn off fat. Though age and injuries have tempered his weight training in recent years, as his latest movies and paparazzi photos show, he’s still in incredible shape—and shockingly muscular for a man of 67 years. He still performs many of his own stunts, and commits to performing some physical activity daily.
