Stars' Summer Style

Grey's Anatomy leading lady, Katherine Heigl, works with celebrity trainer Harley Pasternak to keep herself fit, but doesn't worry about achieving an athletic appearance, "It's just not me and I don't have that kind of discipline," she says. Instead Heigl works with Pasternak to keep her body healthy (she follows his 5-factor diet) and focuses on small but important details like posture. "For me it's never about achieving a look that's impossible," she says.
