Hugh Jackman Bikes Around London

Hot Aussie superstar Hugh Jackman, 42, is keen on going green. Jackman, who is in London for the premiere of his new futuristic movie about robot boxing, Real Steel, took to the streets from Radio 1 Studios riding a fold-up, green and purple bike.

Jackman is an avid cycler and uses it to help him keep in shape, something that takes a lot of effort for the man whose name has become synonymous with The X-Men's Wolverine, one of the most celebrated superheros in comic book lore. "I'm a naturally skinny guy — genetics are not on my side with this thing — so I have to eat like a horse," Jackman told the UK's Daily Mail about having to beef up for roles. "But at the same time, there is a high from how fit and strong you feel. And usually I'm doing it while I'm on another job, so I'm training at 4:30 in the morning, and it's brutal."

Of course, that kind of bulk doesn't come from riding a tiny push bike through the streets of London. And Jackman will need to start training again for the second Wolverine X-Men spin-off, which will start shooting next year. Until then, he's plenty excited about the premiere of Real Steel.

"The fights are unbelievable and very not just, 'Wow, that's cool,' but very engaging and very emotional. There's some fights at the end, I'm guessing there won't be a dry eye in the house." Real Steel hits theaters in the states on October 7.
