Double amputee who teaches Nordic walking

Not only inspirational, this story illustrates the power of Nordic walking as an exercise activity. I have personally worked with people recovering from strokes. I've also seen how the wheelchair-bound can take advantage of the poles and how a woman with scoliosis was able to get in a good walk.

Improve every time you go out

This is more of an ad by Nordixx for their poles, but it contains a useful tip for tracking your progress every time you go out.

Different types of terrain

Notice the Nordic walkers in this photo. On trails they pay more attention to balance in the rough spots and then push off where the trail evens out.
