Although Nordic walking, walking with poles is not really that hard to master - it isn't after all 'rocket science' - starting the activity correctly is important, in order to get the most benefit.
I urge all of you to look for a qualified instructor. Those living in the Washington DC area can take advantage of the free demo classes, which I offer on a regular basis.
Marko Kanteneva is certainly a Nordic walking pioneer. He helped Exel develop their original NordicWalkertm poles and designed the INWA
instructor training program. Here's an opportunity to learn from a true master trainer.
Although 'Original Nordic Walking' is a very good book, there are other good Nordic walking manuals available. David Downer has written the very comprehensive 'Nordic Walking - Step by Step' and Tim T-Bone Arem has put out 'Nordic Walking a Total Body Experience'. Geert Hulshof in turn, has written 'Nordic Walking - Equipment, technique and training'
All of these resources can help you with technique, equipment, fitness and all kinds of other fitness-related questions, but as I said, there is no substitute for a good in-the-flesh instructor.
