Had both knees done several years ago. Also had hips done.
I am 75 ,,going on 55!
Ski every day. In all but moguls!
More technique,,,less muscular moves. I am a better skier now.
Must do more flexibility warm ups. Must learn to watch other skiers, since I have been hit twice due to " extreme skiers"!
Do not do power lifts,,,rather more lower weight reps.
Tog, Whiteroom, & ScotSkier all said essentially the same and helped me get set up on a pair of skis to master the techniques. I must confess, my current gear is antiquated. Volkl P-9s. So I've taken their advice and will be crashing letting the technology do the work for me. I'm looking forward not to just enjoying skiing, but actually skiing again since I haven't been able to for several seasons now.
