Ski touring tips in Alborz in the picture
Well, you can use them, but try and put as little weight on your arms as possible. When I skin I am aware of how I use my triceps and forearms and try to only use them for balance, not to propel myself forward. When the skin track is steep people tend to use their arms too much. Remember your legs are way stronger than your arms, so put 90 percent of your weight on your legs. On a long, flat section in the backcountry I will sometimes just hold my poles horizontally practicing my balance by only skinning with my legs.
