“J turns describe the big curved J shape of the track you’ll make with your skis in the snow. It’s a fun way to introduce kids to the parallel stance, and it’s another way they can stop.
Start out by skiing in a gliding Pizza straight down the slope, right in the fall line. Before you get going too fast, turn across the hill (out of the fall line) and make that curved part of the letter J. You’ll come to a nice controlled stop with your skis pointing back uphill. It might help to have someone else make a big J turn first and then you can follow that track in the snow.”
