I am a skier and today i tried out snowboarding. My friend broke his arm when he fell so that's kinda making me scared to fall so now i have a fear of going fast i am terrified to even get off the bunny hill so any tips would be helpful.
As mentioned, it's all about learning to fall properly and safely and staying within a 'safe-ish' margin of risk.
There are two main golden rules to remember when falling while snowboarding:
Don't stick your hands out in front or behind you to break your fall. Your natural reaction is to do this, but with snowboarding you have to train yourself to stop doing it.
Things like wrist fractures, dislocations etc tend to happen a lot more because people stick their hands out and the force of impact bends their arms in ways it's not meant to bend.
It's much safer to take the impact with everything tucked in and close to your body when you fall and just let your whole body take the fall instead of trying to break your fall with your hands.
So for example, if you fall forwards, you'd want to keep your hands and arms tucked up against your chest and fall with your forearms braced against your chest instead of falling onto your hands/wrists like you'd normally want to do. Instead of falling onto your wrist, then you'd be falling onto your braced forearms and chest, which is a lot less risky.
Rule 2) Go with the fall.
With most falls, the best idea is to go with the fall. What I mean by this is you don't want to fight against whatever direction you're falling and try to stop suddenly, instead you want to just tuck your arms in and let your body go with the fall and let the force get absorbed by the slope as you slide down the snow.
This is why you'll notice if you watch advanced riders in the park falling on jumps or even just on normal runs they'll just relax and slide down the landing before getting back up if they fall. They don't fight against the fall because most times it's better to just let the slope and snow absorb the impact instead of trying to fight it and breaking an arm in the process.
