Here’s another article on the benefits of hiking with a pair of poles. It covers all the basics at the beginning but gets into an area we don’t hear much about in the U.S.: Nordic walking, which is all the rage in Europe. Basically, it’s cross-country skiing without the skis. You move your poles stride-for-stride with your feet rather than every other stride as you might while hiking.

I tend to go Nordic-style when I take my poles out, because it’s the only way I can get much of an upper-body workout while hiking. The article mentions that you burn 40 percent more calories while Nordic walking vs. regular walking, which is nice but don’t forget: 40 percent more calories is 40 percent more work. It’s a lot more tiring.

Poles are great for your lower extremities — not just knees, but feet and ankles, too. I’d caution against using them all the time, though, because the muscles in your legs will become accustomed to a distributed load, so hikes without poles will seem far more strenuous. As with any exercise, it’s best to mix it up.

Owning poles will give you more hiking options. For instance, when I got my insulated, waterproof overboots for mud-hiking season, I reasoned that since the boots add an extra pound per foot (plus the weight of all the mud that’ll stick to them), hiking with poles would help spread the load around and make the hike less hellish for calves and thighs. Worked pretty well, though it was one more thing to clean up when I got home.

My poles are stowed unless I’m backpacking, hiking more than 10 miles or doing mild upper-body training. They’re good to have around but the real question is like all other deal choices: will you actually use them?
