“We only have one body apiece and it’s going to expire sometime, and I’m going to make sure it’s a long, long time from now.” Sage advice from Carrie Underwood. She recently told Women’s Health magazine , the one she’s gracing the cover of right now, that she shed 15 pounds instantly after becoming a vegetarian. Other stay-young-and-beautiful secrets? She also says even though she works out every afternoon, after sleeping in a little, every night she’s onstage is like another workout. Her favorite ways to exercise include boxing, cardio and anything that gets her endorphins going. Underwood also says she’s the most normal person in the universe. Other than the 11 million albums she’s sold, all the No. 1 one hits she’s had and the NHL player she married, I guess.
