Eight ways to burn an extra 100 calories without noticing  

1. Walking (15 minutes at a brisk pace) Regular brisk walks could help reduce your cholesterol and blood pressure levels, and potentially cut the chances of more serious health risks like strokes and heart disease
2. Stairs (15 minutes throughout the day) Stairs are great for toning up your bottom and legs. Make it a habit to run up the stairs at home, and when you're at work or out shopping, take the stairs instead of the escalator or lift
3. Dancing (20 minutes) Nothing improves your leg-muscle tone, fitness and mood more than a good spin. You don't have to go to a club and you don't need a partner - just put on some music and cut up the carpet!
4. Housework (20 minutes) We all have to do it, so make it count. Getting down and dirty with the hoover, washing the windows or scrubbing the floor are great ways to raise your heart rate and tone your muscles. Just make sure you do it at a reasonable pace and use some elbow grease
5. Washing the car (20 to 30 minutes) Don't take it to a car wash - do it yourself and put some effort in. Washing and especially waxing the car works the front and backs of your arms, plus your shoulders and back muscles, making it as effective as press-ups
6. Gardening (15 minutes) Short spurts of vigorous gardening, like digging in compost or raking wet leaves, will boost your fitness levels more than longer sessions or an easier workout, so get stuck in
7. Cycling (10 minutes) Cycling is a brilliant way to tone up your legs, plus it's really good for your heart. And if you've got kids, it's a great excuse to get everyone out into the fresh air together
8. Skipping (15 minutes) Skipping works your heart and lungs, and gives your legs and upper body a great workout too. Start in bursts of two to three minutes, and count each skip so you know how well you're doing - you'll be surprised how quickly you build up fitness.
