Thanks
@trailspud for a thought provoking article. Here is my take on things---I do everything I used to do when my knees were bad---most of the time, I am better at it too. But, I spend time in the gym working on muscles and balance. I am in pre ski conditioning right now and it is grueling. You cannot expect to ski or hike or cycle if you are unfit---you will have to build up your fitness first.
I had a dexa scan recently and my bones are 175% of a normal 71 year old woman. You have to use your muscles. And, do not kid yourself, you have to first allow your knee to heal---for the first month and then, slowly begin to regain your fitness. If you try to rush things you will end up with tendonitits or some other form of pain. Work on things slowly, this is a long recovery, even for us who are athletes.
I skied almost 100 days last year---I ski moguls on powder days but don't do much bumping on icy days. I ski mostly blacks--and mostly off piste . I often ski a half day since I am an artist and have lots of work to do in my studio too. I frequently cross country ski with friends in the evening---we ski and then drink wine, so I am not sure it is truly a fitness thing!!!
