Ryan Reynolds, Blade: Trinity
Back in his Van Wilder days, Ryan Reynolds lived like a frat boy. “I was pretty unhealthy,” he admits. “I didn’t care what I ate or what I drank.” Then came Blade: Trinity, and the comic actor got serious. After three months, six-day-a week workouts, and a 3,200-calorie daily diet, Reynolds gained 25 pounds of muscle.
