It's not easy being Wolverine, the X-Men's toughest mutant superhero – just ask Hugh Jackman.
The Aussie actor, who's played the role in four "X-Men" movies, including his upcoming spin-off, "X-Men Origins: Wolverine," said getting into superhero shape is serious business.

"I was probably training for a year before we started," Hugh told Access Hollywood's Shaun Robinson. "That was the key."
He revealed that he spent an hour-and-a-half every day in training to get the buff body he showcases in the movie, and getting there took a super-mindset.

"I work out imagining I'm Wolverine," he said. "Wolverine to me is the guy that when everybody else quits, that's where he begins. I think that's why people love him."
But Hugh said the biggest change was in his diet.
"I think we've wiped out entire gene pools of chickens," he said. "I know to any vegetarians out there, I really apologize. It's just so much tofu you can eat."

The product of his work is evident on screen – and at home.
"At first [my wife] was like, 'Hugh, this is ridiculous, look at you,'" he said.
"'I don't know who you are – now get into bed,'" he continued, laughing.
"X-Men Origins: Wolverine" is due in theaters May 1.
