I'll take subtle

A few days ago, I had a dull ache in my legs...actually, I couldn't really pinpoint where it was. And I remember being annoyed that I couldn't figure out if it was my knees, hips, legs...or what.

Well, I'll take subtle anyday. I know exactly where the pain is now and it sucks. My knees are killing me. I guess I overdid it on the treadmill. Tonight, I couldn't run at all, so I just did a brisk walk. I don't think I even broke a sweat. Looks like I'll have to switch out my cardio to something a little easier on the knees for now.
