Nordic walking is a sport that started in Finland. It is known that from old times Finns were good skiers. The secret of their success is so called walking with ski poles. It is walking with special poles when there is no snow. Ski coaches in Finland noticed that skiers, who used poles in summer for ski walking, have reached better results and it became a staple for off-season Nordic ski training. Medical research showed that Nordic walking burns 40 per cent more calories than regular walking. Besides, Nordic walking is less harmful for your joints. Athletes with knee pains discovered they could walk longer distances with a pair of trekking poles.
