2 in a row

I did not go to the gym this morning, but that's because I wanted to go for a walk. I forgot my watch, but I'm pretty sure I walked at least 30 minutes and probably closer to 40 minutes. I want to keep building on that. I did feel it in my knees a bit today, but I'm hoping that will get better. I think I will look for new shoes this weekend. Tomorrow...back to the elliptical.
