KRISTIN CAVALLARI

The Hills star shows off her toned arms in a patterned Vitamin A halter cover-up for a game of beach tennis in Malibu. To stay in beach-ready shape, Cavallari works out with trainer Eric Paskel. "Her goals are to define her arms, particularly her triceps and shoulders," says Paskel, who taught her the alligator push-up. "Start in a plank pose and lower down, just hovering above the ground and using hand and feet, walk yourself forward three steps and three steps back. It hits the triceps in a way gym equipment can't."
