Summer Ski Training?

Hello, this is my first post on my new blog, Freestyle Skiing. I am just getting into the sport and I love it. Today I set up a summer setup with my friend in my backyard. I used Astro-turf and a metal pipe for the rail.I had a great time and I highly recommend anybody to do it. Just wet the astro turf with water and soap and have fun. I would really like to progress in the sport by next season and if anybody has any other tips about training, please respond.
