When PEOPLE's Sexiest Man Alive 2012 agreed to star in the summer blockbuster Magic Mike, he embraced the role wholeheartedly, from working out three hours a day to waxing his legs. The 32-year-old even tapped into his experience as a onetime male dancer – handy for filming tricky scenes in G-strings. Tatum's wife of three years, Jenna Dewan, liked what she saw. "She thought it was hilarious," he says. "You know, she married an ex-stripper."

In less than four years, Hemsworth, 29, went from Aussie soap star to Norse god, fabled Huntsman and, next up, leader of a guerrilla-style resistance group in the remake of Red Dawn. With the rise came working alongside today's hottest actresses – including Natalie Portman and Charlize Theron – but it's Hemsworth's Thor director Kenneth Branagh who best summed up the rugged star's appeal to Out magazine: "[Chris] is built like a concrete shipyard and looks very fetching with his shirt off."

If you don't recognize Max Greenfield, his abs or pecs might look very familiar since he plays the mostly shirtless scene-stealing character Schmidt on New Girl. But going bare-chested takes work, Greenfield, 32, reveals to GQ. "I always tell people I'm not one of these guys that was, like, born with like a halfway decent body," he says. "Depending on how naked I am in the next episode, that's how much I go to the gym the week before."

"I don't really believe in judging art, but I showed up just in case," quipped the first-time Emmy winner in his acceptance speech for Homeland. And with that the self-proclaimed "pesky Brit" showed American audiences he had both acting chops and a sly sense of humor. At 41, Lewis uses that same self-deprecating humor to approach filming tough scenes for the Showtime series – namely sex scenes opposite costar Claire Danes. "I'm full of self doubt and self analysis – just like in real life," he told British GQ.
