Great article on a great guy, Trygve Berge. But you don’t mambo by “keeping shoulders pointing downhill as the legs swivel.”

I taught for Stein Eriksen for two years at Snowmass, wrote the book Ski Powder 9 Ways, which included the mambo. It is actually a delayed rotation with the body loose. Here’s how you actually do it:

1. Pick a gentle groomed slope.
2. Point your skis down the fall line.
3. With arms out wide, slowly twist your body in one direction.
4. As that twisting action eventually connects with your feet and skis, they begin to turn in that direction.
5. Now slowly and loosely twist your body in the other direction. Now your skis are moving in one direction and your body twisting in the opposite.
6. When your twisting in the new direction finally reaches your feet and skis and they stop and start turning in the new direction, slowly and effortlessly twist your body in the opposite.

The result? The Stein Eriksen mambo.
