Several of our club members have found the Nordic Ski Lab website useful. The videos and instructions are clear. Videos appear to be made at the Canmore Nordic Centre. The website has a few videos free of charge and the rest is available to paying customers.

A quote from their advertising message:
We have a number of free resources designed to make the sport more accessible to more people, including free instructional videos and articles to help orientate new skiers to the sport.
