Gwyneth Paltrow works out for three hours a day. The 'Iron Man' star - who has two children with her Coldplay star husband Chris Martin - is totally committed to maintaining her svelte figure, according to her chef friend Mario Batali.
Mario, who stars with Gwyneth in TV documentary 'Spain... On the Road Again', said: "I think she works out three hours a day - which is one of the keys to success. If we all did that, we'd all look like Gwyneth Paltrow - or at least closer!"
