Kate Beckinsale's daily exercise fix

London: Actress Kate Beckinsale says she goes "a bit mad" if she doesn't exercise.

The 42-year-old, who has 17-year-old daughter Lily with former partner Michael Sheen, makes sure that she works out every day by either visiting the gym or going on a hike, reports femalefirst.co.uk.

“There isn't really a typical day... I do have to exercise or I go a bit mad, so I either go to the gym and do a bunch, or do circuit training or yoga or go on a hike,” Beckinsale told HELLO! Magazine.

“And I like to keep up with my friends in England, which makes my day a bit skewed. When I'm going to bed is when they're waking up, so I end up staying up quite late,” she added.
