Fitness walkers often neglect their posture. If you slump or round your back while walking, you reduce not only the enjoyment but the benefits of your walk. Slumping restricts your lungs and inhibits your breathing. Using Nordic walking poles automatically corrects your walking posture. Proper Nordic walking technique requires an upright posture that facilitates breathing. You will use a very slight forward lean from the ankles, but essentially an upright posture. Hold your head up and you will achieve a good, efficient walking posture.
