BEN AFFLECK

Violet's dad owes his shape to hours at the gym. Says his trainer of four years, Gunnar Peterson: "Ben's been coming in five to six days a week for 60 to 90 minutes." They vary his workout, but it often involves an elliptical machine. Now, says Peterson, "he's stronger, sinewy and lean." Good thing, as Affleck's next film casts him as George Reeves, TV's Superman.
