8 actors who transformed their bodies for roles
From bulging muscles to skin and bones, the physical metamorphosis of Hollywood stars is an art all its own.
Chris Pratt for 'Guardians of the Galaxy'
In only six months, American actor Chris Pratt went from a goofy pudgy guy on the sitcom "Parks and Recreation" to a ripped action star in "Guardians of the Galaxy."
The new Star Lord says he dropped more than 60 pounds for the role through a combination of workout regimen P90X, running, boxing, swimming and kickboxing. “Three or four hours a day of just consistent, ass-kicking hard work,” Pratt told Men's Fitness.
In addition to the exercise, Pratt also revamped his diet – increasing his intake to 4,000 calories per day and drinking lots of water. "I was peeing all day long, every day. That part was a nightmare," he added.
