Lost 25+ lbs.! "I'm surfing every day," the 42-year-old Scotsman told PEOPLE about his preparation for his upcoming surf movie, Of Men and Mavericks. The 6 ft., 2 in. actor, who weighed in at 197 lbs. for his muscle-bound role in 2006's 300, has also ditched weight-lifting in favor of yoga and cardio and a diet rich in protein and vegetables. "I generally train for a role and give everything to that," he explains.
