I have a friend who wants to try snowboarding, but refuses to take a lesson. They insist on having me teach them. For many reasons this is a terrible idea, but I'm not going to change their mind.
Therefore, how do I teach someone to snowboard who's never strapped a board on before?
I figure I'll show them how to strap in, push around, and get one and off the lift. Then we'll go to the top of the bunny slope and I'll have them do toe side from one side of the run to the other and then stop (crash). Then I'll have them to heel side back to the other side and stop. We'll keep repeating this for a while. I'll also emphasis bending the knees and not the waist and also keeping weight over the front foot.
As for turning, I don't really know how to explain it to someone. I thought that maybe I'd tell them to ease the edge pressure on their front foot to get the board to start pointing downhill, and then to kick their back foot around to change to the other edge.
