Snow hiking/a real complete sport
Walking involves a constant need for balance and, although it seems natural and effortless, are muscles are constantly working to maintain this balance so we stay upright.Hiking on snow increases this physical effort because of the unevenness of the terrain, the slope and the fact that you have to be careful not to slide on the snow all the time. The same with snowshoes, where the physical effort is accentuated even more so.
Walking with poles works your arms, your shoulders and your back, as well as your core as you use your poles to climb up and to stop you sliding down on the descent.
