The 38-year-old sexy celeb looks just as good walking away as she does coming toward you. Surfing and snowboarding help keep her back strong, but she also works out with Los Angeles trainer Teddy Bass several times a week. During their sessions, Cameron does strength moves that engage her upper and lower body at the same time (like lunges with rows). Teddy explains: "Targeting multiple muscle groups at once burns more calories."
