Sarah Jessica Parker can only workout for 22 minutes.
The 'Sex and the City' star, 49, admits she doesn't have the stamina or the motivation to do long periods of exercise, so she makes sure she does a little bit of physical activity every day.
Speaking at the Cannes Lion film festival in France today (17.06.14), she said: "I work out for a sum total of 22 minutes, because that's all I can bear."
However, it might not just be Sarah's low level of fitness that stops her from spending hours in the gym as she previously revealed that she suffers with painful feet after tottering about in high heels for her role in the 2011 movie 'I Don't Know How She Does It'.
Sarah - who has 12-year-old son James and five-year-old twins Marion and Tabitha with her husband Matthew Broderick - explained: "I wore beautiful shoes, and never complained. But then I did 'I Don't Know How She Does It', and I was very thoughtful about my whole wardrobe and said, 'You know, [my character, Kate Reddy] could not afford really good shoes, she would go to Nine West or Aldo'. So I got shoes from there and the bottom of the shoes aren't leather, they are plastic, so I slipped a couple times, twisted my ankle.
"I went to a foot doctor and he said, 'Your foot does things it shouldn't be able to do. That bone there ... You've created that bone. It doesn't belong there.'
"It's sad, because my feet took me all over the world, but eventually they were like, 'You know what, we are really tired, can you just stop - and don't put cheap shoes on us?' "
