A good tip for avoiding knee injuries. Work out your hammstrings. Appereantly because most peoples quads are so overdevelopped in comparision to their hammstrings hard impacts create a shearing motion on your acl which causes it to tear more easily, or so says my cousin that was a physical trainer for the Canadian Olympic snowboarding team for a couple of years. I've been working mine out once and a while during the last two ski seasons and that coupled with stretching I've noticed I can't take way bigger impacts with out mm knees feeling shitty.
