Cameron Diaz's Fit Philosophy

Those incredibly toned arms don't come easy; Cameron stunned everyone with her strength last year when she took to tossing tires to keep her definition. "Exercise for me is like eating, sleeping, and breathing. I'm consistent, and when I'm not consistent, it shows up on my body," Cameron has said. "I get really skinny, and I know it might sound like, 'Well, good for you.' But the body that people talk about is not me trying to stay slim, it's the one where I work hard to keep weight on me."
