PreSeason Workouts

hi there...So, I just joined this group...not sure how active it is...I recently moved to Colorado and LOVE to ski. Since the last time I have been on my skis I have gained about 20lbs. I'm looking for some great workouts that will help me get into shape over the next couple of months before I hit the slopes...

Does anyone snowshoe or XC ski? I haven't done those yet, although, can't wait to enjoy all that Colorado has to offer!!!
