What is so important about...?

Question

My gym class just started an aerobics unit...why do we need to learn aerobics...i might as well skip class and buy my own aerobics video! and what is so important about it?!

Answer 1

It's a way to keep help keep people moving, aerobics (I assume you mean the Richard Simmons kind) don't require too much time out of your day, don't require a lot of space, and are easy for everyone to do.
In my gym class, we had to do units on dancing...
