I find that long boarding in a gently sloping large parking lot is a great way to simulate the carving on a board. I like the long board over a conventional street deck because the lenght makes it handle more like a snowboard. Also the larger, softer wheels make them much better for cruising on asphalt because the wheels don`t get jammed by evey little rock on the ground.
I would also recomend a trampoline for working on balance, spins, jumping anything freestyle will benefit from a tramp use. Also it`s a great workout, does not require you to go anywhere and is relatively inexpensive.
