When you're training for and doing ultramarathons, there aren't enough hours in the day to strength train. So, like a lot of people, I skipped it. I did some cursory stuff, but, as I am now finding out, it wasn't enough.

I'm back at physical therapy once again, doing millions of squats, clamshells, and lunges, because I didn't do them before. Or at least enough of them.

Turns out, afflictions like arthritis can be ameliorated by strength training. It' something we know, deep inside, but kind of ignore it because -- hey -- I feel fine, so I guess I don't need it.

So, listen to Aunt Stubborn and don't skip leg day.
