taking a break

I'm not walking my usual five miles every day. I'm not walking at all. I've decided that walking outside in this heat and humidity is just too hard on my body and for some reason I can't get excited or motivated to get on the downstairs treadmill. I have been doing lots of stretching/joga poses and lifting weights. I'm going to try for Michelle Obama arms before school starts next month. I have also been restricting my calories somewhat. I know that this can be dangerous if I overdo it but I don't feel as hungry in the summer months so I just don't eat as much. Fruit, vegetables and lots of water; what's not healthy about that?
