So. Three weeks in, and my resolve is still strong. I think I may be losing some weight, definitely losing some inches, but I'm not getting the extra energy I want to make up for the 90 minutes a day I'm doing this! Plus, my time is not improving. On the other hand, I'm breaking myself into new shoes, my back is hurting less, and I'm becoming known around town as a walker. Also, I skipped a day walking, but went right back to it the next day. So I'm not a quitter.
