Not Eating Before Zumba Workout

I think I made a huge mistake today in doing interval cardio training on an elliptical climb machine before class today. I burned 300 calories in 20 minutes doing interval training. What I do is raise the meter to 100 which is the highest resistance, and go to level 10 to make a bigger stride. After that I did an hour class of Zumba workout with Jewel. The strange thing was that I didn't really eat much before I went and I didn't have as much energy as I normally do. Maybe it was the eating thing that was the problem. No shake, or meal replacement bar, just water and a bit of fruit. And after I finished the class, I was feeling down, and lazy and worn out. I'm the cause of my own demise I think. And that feeling turned into a bad mood. I mean, isn't working out supposed to release positive endorphins...or maybe only when you give your body what it needs first so it can give you that kind of bonus.

So never again, I will be negligent in fueling my body before an intense Zumba cardio workout.

Lesson learned.
