If this isn't inspiration enough to stay in shape, I don't know what is. Former Victoria's Secret model Gisele Bündchen wasn't keeping much hidden during a seaside photo shoot in Malibu yesterday.

The Brazilian took to the sand in a daring pair of shredded denim shorts that exposed almost all of her derrière. The 5' 11" star was being photographed by Mario Testino, famous for his work with Diana, Princess of Wales and Hollywood's biggest stars including Demi Moore, Madonna and Angelina Jolie.

Gisele, 27, was fresh from a whirlwind holiday with her footballer boyfriend, Tom Brady, who plays for the New England Patriots.

Suddenly I feel the need to do more lunges.
