It's no surprise that 39-year-old action star Kate Beckinsale is dedicated to her fitness routine. When she's training for a movie, Kate works out five days a week for hours at a time; when she's not, however, she scales back to 30-minute workouts four days a week, usually at her home gym. Kate makes sure to mix up her routine with yoga, cardio, circuit training, and core exercises.
