The always active Cameron Diaz was spotted heading to an afternoon workout on Monday (August 27) in New York City.
Looking energetic and ready for her sweat session, the 39-year-old donned a red tank with black yoga pants as she excitedly walked down the Big Apple streets.
In fitness related news, the blonde beauty is set to write a book about health and wellness in partnership with HarperCollins.
According to the publisher, the book will offer advice to young women about health, fitness, nutrition and general well-being. A rep for HarperCollins says Miss Diaz hopes to "engage and empower" women.
