Los Angeles, Jan 29: Actress Cameraon Diaz feels her lungs do not allow her to run long distances.
The 41-year-old says her lungs do not have the capacity because of asthma and smoking for years, reports femalefirst.co.uk.
"I sprint seven blocks and sprint back. I'm an interval girl. I had asthma as a child, and I smoked for so long that I just don't have the lung capacity. Speed is my game," Diaz told Self magazine.
The "Bad Teacher" star also admitted that her lack of endurance ruins work-out sessions with actress-friend Gwyneth Paltrow.
"I'll only last, like, half of it (session). We enjoy working out together, but she kicks my a**. I don't have her endurance. I'm in awe of her," Diaz said.
