CSI's sexy detective William Petersen admits that summer hiatus has always been a problem when it comes to gaining weight. He usually returns to work a size bigger and THAT creates problems. Not this year. He invested in a home gym and hired a personal trainer to work him over twice a week and police his diet. Petersen says that the older he gets the harder it is to lose weight, so he's determined not to pack on the pounds this summer. We love that he shops at Pavilions in Hancock park. Presumably that French bread is for his wife Gina Cirone.
