Amanda Seyfried keeps fit by boxing.

The 29-year-old actress has a set exercise regime which she follows in order to stay ''strong'' rather than look ''skinny''.

Although she sometimes has to skip some sessions when she's shooting a movie, Seyfried feels as though her body gets the best workout when she straps on the gloves and pounds the punch bag.

In an interview with ES Magazine, she said: ''When I'm not working too hard I try to see a trainer twice a week. I do weight training, a bit of boxing and running at the gym. I aim for that 'strong not skinny' look.''

As well as accepting she has a responsibility to her work to stay in great shape, the 'Ted 2' star also likes to look good in designer clothes.

Seyfried's most recent fashion splurge was a pink Chloé coat and she is wishing summer away so she can wear the warming garment everywhere.

She said: ''It may be summer but I've just bought a coat from Chloé. It's pink and beige, a little oversized and goes beautifully with my hair. I just happened to pass the store when I was last in Paris. I see myself wearing it everywhere: London, New York, even around the house. I can't wait for the autumn.''
