Most important is that the poles are of right length. Rule of thumb: your own length minus 50cm or 19.6 inches. For example: I´m 169cm. I have poles that are 115cm.

Movement of arms should be just as if you don´t have poles, that is, like when walking normally.

Poles must allways point backwards. Point of the pole should hit the ground no further ahead than beside the ankle of the forward foot. If the point of pole hit the ground infront of the foot there will be no fluid movement. That is a common mistake to swing the poles in front of the forward foot.

Walking speed with poles will automatically be abit faster than walking without poles. That is because one must put some pressure on the pole, just like in skiing crosscountry.

That´s all I can say with my experiance.

Nordic walking is not hard. If you can walk, you can Nordic Walk. (my own invented slogan )
