Actor Hugh Jackman shows us almost literally every muscle in his upper body in the new “The Wolverine” promo shot on Facebook.  Wowzers!

Having played Wolverine four times – three in the “X-Men” films and once in a solo movie “X-Men Origins: Wolverine” – Jackman is no stranger to the vigorous workouts and strict diets that it takes to get into Wolverine shape.   However, Jackman is not a fan of training for the role.

“I don’t really enjoy training,” Jackman, 43, told Men’s Fitness. “People say it’s addictive, but I’m like, ‘not so much.’ “If I weren’t getting paid or didn’t have a character like Wolverine to maintain, I would just be a tall, lean, fit guy.”

Jackman consumed 6,000 calories a day for his new Wolverine role, along with a high-protein, high calorie diet to add muscle mass to his body.

And back in 2006 when he was training for his first Wolverine movie, it was quite a different story.

“For ‘Wolverine,’ I ramp it up,” he said. “I do an hour and a half a day in the gym and eat a thousand calories more a day than I would normally. And I train really hard. I crank up the Godsmack and Metallica. I yell and scream, which helps me get into the character and have a b*tch of a workout.”

He was bench pressing 315 pounds and was able to leg-press 1,000 pounds.  I wonder if he’s doing much more than that now that he’s “The Wolverine”…

“The Wolverine” hits theaters next year (July 2013), and Jackman’s character travels to Japan, where he faces off with a mysterious figure from his past in an epic battle.
