British actress Olivia Cooke has turned her love of rollerblading into a new exercise routine to keep her fit without having to hit the gym.

The Bates Motel star, 20, reveals she used to skate all the time when she was a kid, and she picked up her wheely cool hobby again last year (13), after realising she could use the energetic activity to tone up her leg muscles.

She tells America's Marie Claire magazine, "I got into it when I was little, four or five, and carried on until I was 14.

"Last year, my mum bought me a pair (of blades) for Christmas. Most people my age are doing something cool, like going to a (music) gig. I said, 'I don't care what people think anymore; this is so much fun'.

"I want nice legs, but I don't want to go to the gym, so I just put on my Rollerblades."
