This morning I had a good power walk; I covered 3 miles in under 45 min which is a good pace. I stopped at the park to do the ab machines & some arm tension weights. I will probably be sore from that tomorrow! Then, I walked the 0.5 mile home at a slower pace. I wish the weather would cool off though. It was 78F with 84% humidity, and that is a chore to exercise in! There was a breeze but it was from the south/southwest, which any breeze off the Gulf of Mexico is a warm breeze that doesn't help much. I wonder if you burn more calories walking in weather like that? I really don't know.
