Daniel Craig has hit the gym for the next Bond film.
The hunky actor is desperate to bulk and tone up before he starts filming the next 007 adventure, tentatively titled Bond 22.
But Daniel, who is also having skiing lessons in preparation for the latest high-octane thriller, is less than keen on his new regime.
A source at Bond producers EON Productions said:
"Filming has begun on the next Bond but it's all been preliminary and filler shots. Daniel has yet to shoot any scenes.
"He's been hammering it in the gym, though. He is 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."
Daniel, 39, who wowed women all over the world when he emerged from the sea wearing a tight pair of blue trunks in Casino Royale, has said the only thing that gets him through the tough workouts is a pint of Guinness afterwards.
The source added: "Daniel joked the only thing keeping him going is to have regular pints of Guinness. He said it's all part of his regime, and that Guinness is really good for the heart."
Daniel has an extra incentive to tone up as he previously revealed he is willing to do a full-frontal nude shot.
He said: "In today's world we expect female actresses to go naked so why not men? I have told bosses I'm prepared to do a full frontal scene. I'm not shy and Bond wouldn't be shy about it either."
