'I don't really enjoy training,' the musclebound star told Men's Fitness magazine.
'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.'
The 43 year-old says maintaining his amazing body is getting harder with age, saying: 'Over the past three or four years it's gotten a lot tougher. I have to eat a stricter diet. I have to train even harder. I can't get away with what I used to.'
Inside the mag, Jackman works out with boxing legend Sugar Ray Leonard who helped him prepare for his role as a fighter in upcoming movie Real Steel.
