Kellan Lutz pushed himself hard for 'Immortals' role

Kellan Lutz has revealed the secrets to his buff body in upcoming movie "Immortals" - he ate 16 eggs every morning as part of a strict diet and fitness regime.

The Twilight star bulked up to 220 pounds for the mythological Greek epic by following a specially-devised eating plan.

As a result, Lutz had energy to spare and he regularly worked out on set with his co-stars Henry Cavill and Luke Evans to stave off boredom.

He tells Men's Fitness magazine, "I ate 16 eggs every morning. I got up to 220 pounds of solid muscle. We'd work out every day.

"Shooting one scene could take all day - and when that's just driving a Humvee at five miles an hour, we had energy to burn. We were doing push-ups on top of the Humvees. We were throwing wheels and rocks. We were timing each other, betting who can do the most push-ups, just to keep our sanity.

"Within 30 minutes, you're dripping. And it's Africa. So it's hot as balls out there. We pushed each other to be the best we could be."
