My First Demo

So, for my certification class we have to make a workout demo.
My first issue, what in the name of all that is holy is that supposed to mean?
We had to pick songs with a constant beat and design our own workout to them and they have to be at least 10 minutes long. So instead of making my own, I asked if it was okay if I took songs from Less Mills Body Combat and it was. So I taught my very first intro to combat class.
The rush was beyond words, I was nervous but excited. I knew what I was doing but at the same time my mind was going blank. Giving safety cues, watching form, keeping with the beat, and making sure I had the right songs. These were my main worries. I stepped up in front of that class and I let the fire inside out. Before I knew it, my demo was over.
It went so well. I could have yelled louder and said my cues better but all that matters is that I actually made it through without freaking out.
