(Cover) - EN Star Style - Olivia Wilde took up martial arts to achieve her toned body for TRON: Legacy.

The 26-year-old actress and model plays the character of Quorra in the sci-fi film, in which she boasts a highly sculpted frame.

Olivia has revealed her figure in the movie was crafted from hours of hard work every day, doing cardio, weight training and mixed martial arts to maximise her fitness and achieve her sleek physique.

However, she enlisted the help of a professional to motivate her to the challenge after a hard days work.

"I worked with a personal trainer, so I did about an hour of cardio five or six days a week, weight training three times a week, mixed martial arts/fighting three times a week, and thats a lot more than my normal [routine]!" Olivia told Womens Health.

The star revealed she is proud of her body and the way it looks in the much-hyped film, which tells the story of a virtual-world worker who tries to take down the master control programme. (C) Cover Media
