OMG! Way harder than I thought! There wasn't a beginner class available when I was so I went to a "moderate" one. The owner said I would be OK as the instructor only has a few people in that particular class. There was only two other students. They said for a first timer I did pretty good, but I'm pretty sure I'll be sore here and there tomorrow.
The instructor looked like she was about 100# and couldn't open a pickle jar that wasn't previously opened. Wrong! I'm pretty sure she could open jars I can't.
All I kept thinking through the class was "why the heck didn't I start this in my 20's?" I'm playing catch up at 54.
Many things we did I saw as an instant benefit to skiing. If nothing else but for the range of motions and balance.
If you've been on the fence, go for it. Glad I did. Sorry I waited so long.
