Revealing his bulging biceps, the star looked like he was in immesne pain as he lifted up weights at the gym.

Wearing a towel across his sweaty head, Dawyne gritted his teeth as he posed for the camera.

Talking about his routine, Dwayne said: ‘I do steady-state cardio for about 35 to 40 minutes at my home gym. Or I might hit the road out in the neighborhood. And then I’ll go train.’

However, Hugh Jackman recently revealed how Dwayne gave him ‘insane’ advice when he was trying to bulk up for The Wolverine after finishing filming Les Miserables.

He had said: ‘I called my buddy The Rock for tips. I lost weight doing Les Mis.

‘He said, “Here’s the deal – three hours in the gym and 6,000 calories, eating very lean. You gotta do that for six months.”

‘I did it and let me tell you, The Rock is crazy! He is insane. But we did it and the results are there.’

Dawyne will next be seen in the Fast and Furious 7 which also stars Kurt Russell.
