The principal benefit of Nordic walking as compared to regular walking is that it engages most of the muscles in your body. This allows you to get more overall exercise in the same amount of time as you do when you do regular walking. This is a great overall conditioning workout for people with limited time for exercise. You burn more calories than with regular walking. You don't use as many calories as when you run for the same amount of time, but it gives you more upper body conditioning than running. Nordic walking, as a low impact exercise, is much easier on your joints than running.
