Kellan Lutz is ditching his vampire role as he embodies one pivotal character in Greek/Roman mythology: Hercules. Playing the role of a half mortal and half god in 'The Legend of Hercules', it is only apt for the 28-year-old actor to have a strong and muscular body. What exactly is Kellan Lutz workout for his Hercules role?

"While shooting Hercules, I adopted the Paleo Diet. So I really deleted sugars and deleted carbs and dairy and some other things. And you really just notice that your body will adjust, and you feel healthier," explains the rumored boyfriend of Miley Cyrus.

According to the special diet's website, it is "the healthiest diet that mimics the diets of our caveman ancestors, includes meats, seafood, vegetables, fruits, and nuts." When it comes to exercise, the Kellan Lutz workout primarily includes the action scenes in the film.

"Riding a horse works out your legs and your stomach. Wielding the sword works out your shoulders and your chest. And then I was pretty much in a skirt the whole movie, so I was doing pushups for the chest. You know I worked hard. I really did," says the 'Expendables' actor.

With his recent roles, does Lutz see himself as one of the hottest guys in the industry? "No. By all means, no," the actor says to She Knows.

'The Legend of Hercules' is scheduled for release on January 10.
