Robert Pattinson has revealed he had to train to run like a true action hero for new Twilight movie Eclipse.

The 24-year-old Hollywood heartthrob confessed to Reveal magazine his run in the first two Twilight films as brooding vampire Edward Cullen had been a bit weak, so he hit the treadmill.

Robert laughed: "I had to learn how to run properly. In the last two films, I ran in a limp/skip. I had to run more solidly this time so I spent a lot of time on a giant treadmill. It was like one of those things that mice run around in."

Robert also had to brush up on his fighting skills for a scene with new co-star Bryce Dallas Howard, who plays villain Victoria.

The actor admits he used a body double for the most dramatic parts, but movie bosses were still impressed with his action moves.

Robert revealed: "Weirdly, one of the producers told me: 'Wow, you look so enthusiastic in that fight scene. Much more than in any other one in the series'. It's always hard to do stuff with Bryce because she's the gentlest person and is always laughing. And she's afraid of hurting me!"
