Mayo Clinic – Walking poles work your arms, shoulders, chest and upper back muscles

Walking poles work your arms, shoulders, chest and upper back muscles through a full range of motion as you walk.

Think of it as cross-country skiing for walkers: With one walking pole in each hand, you grip the handles and push off with each stride. The arm movement adds intensity to your aerobic workout, which can help you burn more calories. Visit External Link
