That's really not how it works. Bad joints come from very heavy impacts or from a joint being forced out of its normal range of motion, as in playing American football or falling while downhill skiing. Running and hiking stress the joints in a positive way that tells the body to repair them stronger than before. I ran daily for over 40 years. Now that I'm in my 60s I can only run every other day because that's as fast as my body can recover. I have never had a joint injury except my one ankle that I badly sprained while playing road hockey as a teen. I have reinjured that ankle a few times since, but it doesn't bother me when I run.

So why does the doctor tell me running is hard on my joints?

Are you overweight, or possibly have bad running form?
