Physics in Motion

I own a small building downtown, and one of the units in that building is rented out to a fitness company that holds classes, the sort you might see taking place in a gym. Karate, cycling, Tae Bo, you know the sort of thing I'm talking about.

Well, the other day I was down there checking up on things, and a karate class was just finishing up. Now, there was an aerobics class of some kind called Physics in Motion, which was supposed to start right afterwards. Unfortunately, as far as I could tell, the instructor wasn't there. She simply didn't show up. Of course, the people taking the class were there, and they wanted their exercise!

Obviously, I too wanted them to have their exercise. I wanted their money! So I did the only natural thing that any reasonable property owner would do, which was to pose as a substitute instructor and lead the class myself. I gave a little spiel which proceeded in a manner similar to the following:

"So, everyone gather around, Physics in Motion is going to begin. Your regular instructor isn't here tonight, but apparently I'm some kind of fitness expert, so I'm going to lead instead. You see, in aerobics we move our bodies a lot, and I guess the basic idea is that you sweat a lot and therefore start burning fat or something like that. I don't know, but people do this stuff, so I guess it works. Anyway, today's animal is the speed leopard! Er... I think it was maybe the cheetah? Nevermind, let's get started."

So I started to jog very lightly in place, and the people enrolled in the class followed suit.

"This feels pretty good. Starting to feel the burn. Yeah, that's good! Getting in shape!"

We continued to jog in place like this for about a minute.

"Let's just keep this up! This is good! Nice form, everybody!"

Finally, someone said to me, "I don't think this is going to work."
