London, Sept 19 (ANI): Daniel Craig is hitting the gym once again to get into shape for the next Bond film. However, not being a fitness freak means that the only thing that keeps him going while working out, it the thought of a pint of Guinness that he gets to guzzle after sweating it out.

Craig, who wowed men and women alike with his buff bod in Casino Royale, is getting back into shape for the new James Bond movie with a gruelling exercise regimen.

A source at Bond producers Eon says that Craig isn't finding hitting the gym easy, and the only comfort he finds is in the regular pints of Guinness after a workout.

"He's been hammering it back in the gym, though. He's really starting to get even more toned than before. But he's told us he's not a fitness freak so it's really tough getting to the gym. The only thing keeping him going, he said, is regular pints of Guinness," the Daily Express quoted the source, as saying.

"Daniel says it's all part of his regime - and that Guinness is good for the heart."

The source also revealed that while filming on the new 007 movie, till now simply known as Bond 22, has begum, Craig has not filmed any scenes.

"Filming has begun on the next Bond but it's all been preliminary and filler shots. Daniel has yet to film scenes," the source said. (ANI)
