Henry Cavill: There is nothing ordinary about Cavill's body, star of the latest Superman movie and fantasy film The Immortals. The British actor beefed up for Man of Steel using the same gruelling workouts as the US National Guard, training with dumbbells that were bigger than his head.
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. He says he eats 6,000 calories for 8 hours of each day, and fasts for the other 16 hours. But Deborra-Lee Furness says her husband looks photoshopped in the flesh. PA Photo/Fox UK.

Justin Bieber: The 19-year-old knows how to please his fans, by sharing 'shirtless selfies' of his young physique on Twitter. Bieber is now believed to have at least 16 tattoos, with the latest a drawing of his mum's eye - 'always watching'.
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. He then truly won us over when he played smooth-talking con man Face in The A-Team, involving plenty of shirtless shots of his pecs and abs.
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.
Mark Wahlberg: He has always been in great shape but it was for his starring role as American boxer Micky Ward in The Fighter that the Hollywood star got superfit. Meanwhile his co-star Christian Bale looked emanciated as he barely ate anything to shed pounds for the role of Ward's drug addict brother Dickie Ecklund.
