Actor Matt Damon worked out four hours a day to achieve his rippling physique in the futuristic sci-fi thriller "Elysium."
“We wanted [my character] to look a certain way so I had to keep up a workout regimen,” Damon told Entertainment Weekly.
"I had to just literally go to the gym for, like, four hours a day," Matt told reporters at Comic-Con 2012. "Which was kind of fun in its own way at my age, to be given an excuse to do that, because it’s not something you'd ever really do otherwise!”
Matt's workout routine included hours of weight-lifting and cardio exercise with an emphasis on core strength because he wears a heavy, high-tech exoskeleton that gives his character super speed and strength.
“It’s kind of like wearing one of those old Bo Jackson weight vests,” says Damon, 42. “It’s really insidious trying to carry extra weight even if you’re in shape. You just really need a pretty strong core or you can get injured pretty easily, particularly at my age.”
Undergoing drastic body transformations is nothing new for Matt, who lost 40 pounds for "Courage Under Fire" (1996); slimmed down again for "The Talented Mr. Ripley" (1999); got buff to play CIA assassin Jason Bourne in the "Bourne" trilogy (2002, 2004 and 2007) and gained 30 pounds for "The Informant" (2009).
Damon admits the constant weight shifts are hard on his body, especially as he gets older. One action star he's in awe of is Tom Cruise, who at 50 remains as fit and youthful-looking as ever.
“Tom is the best," says Matt. "He genuinely looks fast to me. I’ve never seen him run in person, but when he runs in movies, he is really going fast. I have a feeling that in a footrace, he would really smoke me.”
