It works your upper body, arms and trunk, as well as your legs and burns 20 per cent more calories than normal walking at the same speed.

Nordic walking, which was developed as a sport in Finland in 1997, originated from cross-country skiers who used it to keep fit in the summer months. The Finnish are even known to walk to work using their Nordic walking poles.

By 2001, it was estimated more than 12 per cent of the Finnish population were regularly Nordic walking.

But you don't have to live in a mountainous country to benefit. Nordic walking has moved across the continent to these shores and is now beginning to get a following in the UK.

Stride along the Downs with your poles taking in the spring scenery as you go or even try a Nordic walk along the seafront.

By pushing off with a pair of specially-designed walking poles, you will work your muscles - including those in your upper body - get your heart pumping and burn more energy than normal walking. But because the effort is spread throughout the body it feels easier and less tiring.

Raija Kuisma, Nordic walking instructor and senior lecturer at the School Of Health Professions at the University Of Brighton, says: "It is an exercise where you can get the training aspect without feeling you are pushing yourself too much.

"It makes you work hard without actually noticing it."

Wai Ming Loh, an instructor and student who has been writing his Masters dissertation on the effects of Nordic walking on older people, was given his first taste of Nordic walking during the London rush hour.

"You can work as hard as you want to," he says.

"No matter how fit you are, you can get benefits from it.

"It can also be quite sociable as you can walk with another person or a group of people."

BENEFITS Burns at least 20 per cent more calories than normal walking while going at the same speed
Increases your aerobic fitness and endurance
Use muscles and movements you don't normally use when walking because you tend to take longer steps
Works your whole body, including your upper body. As well as leg muscles, it works arms, shoulders, upper back muscles and trunk muscles
Can help ease back pain by encouraging you to rotate the spine more which strengthens the spinal discs
Can reduce neck and shoulder tension through the use of the poles
Can help reduce symptoms of repetitive strain injury (RSI) through squeezing and releasing the grip of the pole
Reduces the load on your knees
Strengthens bones and so can help fight the effects of osteoporosis
Can be sociable if you do it in pairs or groups. Everyone can walk at the same speed but work harder by using arms more
Suitable for older people with the support of the sticks.

TRAINING TIPS Raija and Wai suggest these tips:

Take a session with an instructor if you haven't tried it before. If you get into the wrong habits, the benefits could be lost
Start with a warm-up. Aim for about half an hour of Nordic walking at a moderate intensity pace and finish by cooling down with some stretches
Aim to walk three to four times a week, half an hour at a time
Increase the intensity by walking further, faster, using your arms more and going up hill
The talk test is a good indication that you are walking at a speed you can manage. You should be able to hold a comfortable conversation while you are walking
Keep hydrated. Take some water with you and, like any exercise, wait for two hours after eating a heavy meal before you go out on a walk.
