Do you ever watch skiers slither down massive lines and ask yourself, “How on Earth do they do it?” Well, good news: Henrik Windstedt and Peak Performance are releasing a four-part series dubbed Sketchy Lines that’s super informative on the topic.

Through animations and narration, the Swedish ripper explains in the video, above, what it was like crushing a gnarly route deep in the Alaskan backcountry. Enjoy, and stay tuned for more episodes in the coming weeks.

Ski extreme! ????If you like skiing and want to follow through the history of our sport you should watch the Generations of Freeskiing documentary on demand at Red Bull TV. It's a good one! #extremeskiing #documentary #redbull #badacting @redbull
