Beckinsale ate vegetarian for many years, but started eating fish and chicken at the suggestion of her trainer. "I was a vegetarian for a really long time because I am incredibly squeamish about meat,” she told Shape. “But when I was filming Pearl Harbor, I didn’t have enough energy, and the trainer I was working with at the time said ‘You’ve got to start eating chicken and fish.’ So I did, and that helped me.” In general, she maintains a clean diet. She dished to Delish that she triest to avoid sugar and refined carbohydrates as they make her feel “very sluggish.” She tries to eat protein and vegetables, which “suit my body very nicely,” she said.

To complete the workout, Kate’s helped her do some stretches, revealing just how flexible she is. “Do you have any bones?
