Hahaha, it's so hard to strike that right balance of fit without being injured... but I'd certainly prefer to have overuse injuries than metabolic stuff for sure.
I've heard of the golf ball trick for my heels before, but I didn't actually realize it was supposed to be a relaxing thing, I thought it was more like a painful massage, so I had only tried it once while I was standing. I'll try it again while I'm sitting and see how that goes. Thanks!
It can be relaxing or painful, depending on how hard you do it! :)) For me the advantage is that is a really easy fix, and one you can do almost everywhere. Let me know if you try it!
