"Katie does 20
minutes of working out with kettle bells two to three times a
week," says her trainer Missy Beaver. Swinging the cast-iron
weights helps "establish long, lean muscles." Another way to
achieve a toned torso? Doing dumbbell back rows and tricep
extensions, which "help with improving your posture, lifting
your boobs up," says Harley Pasternak, who's trained the actress
in the past.
