Michael B. Jordan, who got his break as The Wire's sensitive kid Wallace and raised his profile in last year's Fruitvale Station, knows he needs to be able to bulk up on command if he wants to break into the A-list. "You've gotta be ready to take off your shirt," he says, and he will as the Human Torch in next year's Fantastic Four movie. "They want to blow you up and put you in a superhero action film. Being fit is so important. . . . The bar has been raised." Even in the late Nineties, Hollywood's biggest stars Nicolas Cage, Keanu Reeves, Harrison Ford, Denzel Washington, Will Smith were handsome Everymen, athletic but not jacked. Now even Tom Cruise and Bruce Willis, who is pushing 60, are more chiseled than they were in their prime.
