Kristin Davis "pours sweat" when she works out.

The 'Sex And The City' actress has been working with celebrity fitness trainer Tracy Anderson in a bid to get in shape and admits she has found their sessions more gruelling than she expected.

She said: "I mean, it's a hard workout. I pour sweat. Every piece of clothing I have is wet when we finish. It sounds a little gross.

"I didn't realise, but I had been developing my abs kind of outwards. We don't want that!"

Despite working out for two hours a day, the 45-year-old actress has accepted she will never be "the thinnest" but is happy with her body shape.

She said: "I have hips. I'm never going to be the thinnest actress, and I don't want to be. When you're at peace with yourself and your body, you're automatically more confident.

"I can't just hop on the treadmill. I need to mix things up and enjoy what I'm doing."

Kristin is also in awe of her close friend and co-star Sarah Jessica Parker's discipline, but thinks she looks "amazing" even if she doesn't look after herself.

She told Fitness magazine: "She's one of the most motivated people I've ever met, and she has an amazing body even when she doesn't work out; though like the rest of us, she doesn't feel that way. For me, it's more fun when I have someone to go with."
