Movie Star Workouts
THE ROLE Seductive superhero the Black Widow in Iron Man 2
WORKOUT PLAN Scarlett Johansson teamed up with husband Ryan Reynolds's longtime trainer Bobby Strom five months before filming to get in bodysuit-worthy shape. "When I met Bobby, the first thing I said was, 'I have to wear a Lycra catsuit!'" Johansson says. "He was, like, 'Calm downand walk on this treadmill.'" They worked out for 90 minutes, seven days a week and kept a strong focus on her nutrition. "She really hated working out, she'd done it for a past film and had a bad experience," he says. "It was a transition, but once it happened she loved working hard."
