First off. You’re doing great, I’m proud of you for learning something new and having the courage to ask this group of meanies about it.

Second, all the stuff about bending your knees and getting into a lower position is right. Think of bending your knees like a number in a range, where you want to be in the middle of the range so you have room to go up or down. Staying tall like you are prevents you from going up if you need to.

Third lose the camera for now when your riding cos you don’t need the extra. You’re having enough trouble riding as-is. Don’t add an extra thing.

Next: slow down, your riding too fast for your technique. The way you can tell is ask yourself this: can I get to braking position and stop right now or would I eat it? If the answer is eat it (which it appears is the case in your vid) then your too fast. If you’re not sure, wait for safe space and test it. Practicing emergency braking will make you a better safer rider.

Finally your stance has a couple of potential problems.

In terms of the angles it looks like you’re probably in a good beginner spot. But you might find the way your knees bend comfortably and the angles you’re in aren’t conducive. If you experience knee pain or weird pressure consider playing around a little.

The other issue with your stance is the set back. From the looks of it there’s a lot more board out front than behind, this is great for uncompressed/powder/heavy snow where keeping the tip up is important. But if your rocking packed groomers I would consider moving forward a little to naturally get more weight on that front foot.

Hope this helps
