Anne Hathaway did sit-ups before filming sex scenes in 'Love and Other Drugs'

The actress, who stars opposite Jake Gyllenhaal in the upcoming flick, said that she used to do sit-ups and push-ups to prepare for being nude on the set.

"I would go into my trailer and a make-up artist would put body make-up on me and then - girls will relate to this - I would compulsively do sit-ups and push-ups until they needed me on set," News.com.au quoted her as telling The Daily Telegraph.

"But then we would do the sex scenes and afterwards we would just be Jake and Annie chilling out. It was very innocent," Hathaway added.
