Ho Hum

I just got back from my walk and once again, I'm wondering why I'm so tired. I always hear people talk about how great they feel after working out. Not me, so siree. I have a snack about an hour before my walk to make sure there's enough fuel in the tank, and then I eat lunch when I get back from my walk. Yet everytime I get the exercise low, and I've got to tell you, it's not exactly the motivator I'm looking for! I would really love to feel better. Perhaps more research is required . . .
