Every person learning how to ski eventually falls. To continue skiing after a fall, it's important to learn how to stand up on your own power. Untangle any arms or legs that have gotten crossed. Rotate your body so that your head is uphill and your skis are downhill.
Face skis across the slope so that they are pointing neither uphill or downhill.
Place your hips above your heels while on the ground. This can be done by bending your knees, tucking your feet into your body and leaning forward. Plant a pole on either side of your body. Push down on both poles. Push up with your legs.
