Use both poles.
Using a single trekking pole can create strain on one side of the body and compromise balance.
Hold them correctly.
Bring your hand up through the bottom of the loop, then straight down on top of the strap, so it lays smoothly across the back of your hand. Avoid gripping the poles tightly, which can create strain all the way up your arm to your neck.
Conventional wisdom suggests that on even ground, arms should bend at 90 degrees when you’re holding poles, but this isn’t always best for everyone, Paley says. It’s more important to be comfortable than to go for a perfect right angle.
Adjust length as you go.
Make them shorter on uphills and lengthen them for downhills.
Plant poles carefully on slick terrain.
Position poles straighter up and down, because angled poles tend to slip more easily.
On steep, off-trail terrain, use poles to ease your weight down so you’re not jumping onto uncertain footing.
Make stream crossings safer.
Lengthen poles for deeper water, and make sure pole tips are planted securely on the river bottom.
Keep it natural.
Poles do the most good if you continue to walk naturally. Let your arms swing normally.
Engage your core.
Don’t simply move your arms back and forth. Keep your core involved, as this helps take further pressure off of your knees.
