I find dryland training to be one of the best ways to get in shape for the approaching ski season. Liberty Mountain Racing Team (LMRT) has a nice dryland program that I enjoy participatng in. We use lot of high impact plyometric exercises involving jumps, sprints, etc, as well as some yoga. It's lots of work, lots of fun, but most of all it pays off. I highly
recommend it. Here are some pictures. They were taken the day after the pre-Halloween snowfall (it all melted).
