After pulling a muscle in my back earlier this week I was finally able to go back to the gym to Zumba today, or as my daughter calls it jingly butt Wednesday. After not going for over a week I feel lethargic and tired all the time. Can't wait for those endorphins to start pumping again so I can feel like the new me felt two weeks ago. No wonder I just used to sit around and be tired all the time, this is no fun. I always used to dread exercising and now I look forward to it. Plus, the people at the gym are so much fun and I've made some really good friends there.
