How to improve snowboarding park skills without a trainer or camp?

sparked asked:


I’m a 19 year old male and I’ve been snowboarding for quite some time now. I’m starting to get a little discouraged in the terrain park, however. I can go through the motions on rails, boxes, and jumps, but I can’t seem to do anything extensive without wiping out. I know this question seems a bit vague, but I was simply wondering if anyone could share their stories of how they improved in the park, or possibly give me some pointers on how to improve without completely injuring myself. Thanks!
