It is important to stretch well before skiing, especially the buttocks, thighs, knees, shins, and ankles. These muscles are used the most when skiing, along with the biceps.
You can stretch out your muscles, build muscles by doing sit ups, crunches, push ups, etc. I myself use one in morning and at night to do my crunches. The lift off the ground puts more stretch to your muscles so it benefits using one.
