Keira Knightley hates going to the gym.

The 'Atonement' star - who looked stunning at last nights BAFTA Awards (10.02.08) in a grey Valentino Couture strapless dress - insists her toned figure is not down to a "boring" exercise regime.

She said: "Gym work is boring and repetitive. I'm not a gym person at all. The most exercise I get when I'm not working is when I turn on the radio."

The 22-year-old actress also revealed she even finds low intensity activities like yoga tedious.

She said: "I really like yoga but I can't do it. I tried to get into it but it just p****d me off.

"It actually really tenses me up, the whole breathe and relax thing. If anyone tells me to relax, I tend to tense up."

Keira missed out on the Best Actress award to French star Marion Cotillard at last night's London ceremony. However, her spirits were lifted when 'Atonement' triumphed in the Best Film category.
