If you can burn an extra three hundred calories, six days a week, that's enough to lose an extra twenty five pounds in a year. There are lots of ways to sneak in exercise without it taking any extra time out of your day.

Just find three of these ten suggestions to fit in each day, Monday-Saturday:

1. Roll up your sleeves and spring-clean a room for twenty minutes


2. Do an extra ten minutes on the cross-trainer or the rowing machine at the gym.


3. Stroll to the local shop (fifteen minutes there and back) instead of driving.


4. Each time the ad breaks come on, do a three-minute exercise blast: crunches, press-ups, jogging on the spot.


5. If you work in a desk job all day, take a five minute break every hour to stretch and walk around the room.


6. At work, walk to colleagues' offices and chat face-to-face, rather than emailing.


7. At the supermarket, park at the far side of the car park. Use a basket, not a trolley - it helps tone your arms.


8. Each time you're waiting for the kettle to boil (two minutes) do stretches and squats. While dinner is cooking, run up and down the stairs ten times.


9. When waiting for a train twice a day, walk around the station for ten-fifteen minutes.


10. At the weekend, spend ten minutes shooting baskets, and fifteen minutes playing Frisbee.
