Writing and Working Out

I joined a gym. I decided I needed more activity than just Kung Fu twice a week. More aerobics. My cardio is horrible. I can barely jog a mile. So I decided to take an aerobics class at the gym. I'm in worse shape than I thought. Five minutes into the warm up I was huffing and puffing. But I stuck through the whole hour. It was a great workout. Keep this up and I'll be running a marathon in no time. OK, not really. I have no desire to run a marathon. But I'll be in better shape. The workout left me pretty tired. "They" always say not to workout before bed, because you won't be able to go to sleep. I understand the theory of the endorphins or whatever running through your system, but I never have that probelm. A good hard workout and I'm ready to pass out. I took a half hour power nap on the couch after a shower, then got to work writing. 1500 words. I'd like to write more, but I'm tired, and my head hurts a little. I think I'll play with the puppy for a while then see how I feel. But still, 1500 words is good progress. I still don't quite know where the novel is going, but every time I write it flows out easily, and I just can't get enough time to write.
