Ready to step up your hiking experience? Using a Nordic walking pole (also called a trekking pole) is a great way to not only increase your workout, but provide relief from the stress your body takes on hikes. Using trekking poles can reduce fatigue, provide stability and increase a hiker's speed by providing regular rhythm.
