Original Nordic Walking technique - How to get started?

In Original Nordic Walking, the rhythm and movements of the arms, legs, hip and body are similar to normal, brisk walk without poles. In Nordic Walking, the opposite arms and legs move rhythmically forwards and backwards alternatively just as in normal walking but more efficiently and with wider movements thanks to pole thrusts. A longer stride is one indication of a proper and efficient Nordic Walking technique.
