Brazilian supermodel Gisele Bundchen believes fitness can't be neglected during pregnancy.

The 29-year-old model gave birth to her first baby, Benjamin, with husband Tom Brady last year.

'I did kung fu up until two weeks before Benjamin was born, and yoga three days a week,' contactmusic.com quoted her as saying.

'I think a lot of people get pregnant and decide they can turn into garbage disposals.'

'But it is important to look after your body while you are pregnant,' Bundchen said.
