Ryan Gosling: Emma Stone's character in Crazy Stupid Love wasn't wrong when she exclaimed "Seriously? It's like you're Photoshopped!" the moment Gosling took off his shirt. It even led Cosmopolitan to ponder what was the secret behind his universal sexiness. Core strength, according to his trainer.
Hugh Jackman: Women the world over have drooled over Wolverine, but Hugh Jackman's wife isn't actually a fan of the body he has worked so hard to achieve.

Channing Tatum: Men who have been forced to watch 'that' film about male strippers with their wives and girlfriends have been left envying Tatum's body, with male health and fitness magazines showing them how to follow the 'Magic Mike diet'. He underwent a strict regime again for his latest film, Fighting, but this time he had to shed the weight to make him look more agile.
Bradley Cooper: He made a big impression sitting alongside pal Gerard Butler at the 2013 Wimbledon final. But long before that, Cooper had reeled in female fans across the globe by shaping up for the Hangover.

The British and Irish Lions: Yes, we have selected the entire team who in one photoshoot during the tour to Australia laid to rest all the old images of rugby players sporting beer bellies and battered faces.

Daniel Craig: The blond hunk brought a muscular edge to the role of James Bond when he first starred in Casino Royale, surprising the critics when he appeared in 'that' ocean scene. Not only did Craig's itsy bitsy pair of blue La Perla trunks turn Bond from a male icon into a female fantasy, but they later fetched £44,000 at a Christie's auction.
