Get the Bod: Britney Spears This week belongs to Britney Spears. Britney worked hard getting back into world-tour shape, and she admitted to Glamour magazine that she thinks going to the gym "isn’t fun . . . so to do it every day would be horrible. Three days a week is cool, even two. It makes me feel good and feel like I’ve done something. It's important to take care of your body."
