I'm going for a one week long trip to learn snowboarding in the Alps. I was told by a friend that after the first day, your body is exhausted, and doesn't recover for several days. I imagine this is because snowboarding intensively uses muscles that are not normally used so.
So, in order to make the most of the trip, I would like to train some of those muscles in advance. But I have no idea which muscles these are (so cannot figure out a proper workout).
I would like some one with experience on snowboarding to give me some information on what muscles are key to snowboard (particularly for beginners). A set of exercises particularly tailored for snowboarding would be most welcomed too, but not necessary.
Thanks!
