Cross-Country Skiing requires lessons. If you can't take a lesson, watch a video. Taking lessons and watching videos can really help you grasp the complexity of the gliding with ease on snow crystals. 2 years ago, I spent the time to make these cross country ski technique videos - for both classic and skating - and published them, making them free for all to learn and improve from. Enjoy! Hope you find them helpful.
