I agreed with all the awnsers. Also make sure you are fitted correctly as either a regular (righty) or goofy (lefty) footed.
When I first started the ski shop physically pushed me from behind and because of the way I regained my balance they determined I was goofy footed which turned out I wasn’t.
If you are predominatly right handed then you will be a regular if you are predominatly lefty you will be goofy.
Keep in mind if and when you take a lesson and you are goofy you will be mirroring the class otherwise you will be riding backwards all the time. That is not a bad thing but not necessary a good thing when you are first learing to ride.
It is an awesome sport and addicting as all get out!! Good luck!
