These are the best videos! Fantastic science! Spent a wonderful winter with Per Olof Astrand in Stockholm. Stunning science!

"You're about to enter the Swedish Winter Sports Research Centre" It just flows of the lips, lol. Great Vid.

Thanks for a great video

I wonder if that's where klaebo's grandfather got the idea..

the woman is right on about games like soccer on skis for both fun and skill building... the "games" at the end are not games but really drills or challenges that only a very advanced skier with highly developed balance could use...not games that would be useable in say Bill Koch League except for a very advanced group.

I see scientific measurements being taken but they are not referred to. Sad. Also the how-to isn't discussed quite enough, though "flat and narrow," "quiet upper body" and "there's room for fast cadence" are helpful. An even more helpful view, I think, is that our posture, and dynamics shd be the same as our other techniques (which are the same across skate and classic): forward fall, ankle flex, arm bend. In the old 1990's Norwegian Tapes that came to the US, herringbone was given indirect respect because it was used interchangeably with striding to illustrate good form. They didn't call it out, but this taught that we needed to treat herringbone the same as the other moves. It then becomes much more fun. Something else not mentioned: the steeper the climb the more time spent on it: improvement there gives big payoff. The herringbone is your friend! :) (I think the "skidaddle" skill for side-slopes, offcambers and gullies also should be taught. These are real world conditions if not YET part of WC courses. Look it up! It's not sidestepping.)
