A short term gym membership sounds like a good idea. Who knows, you might really like it?
There are different types of trainers and some are noisey but the magnetic ones are quieter. I set mine up in front of the t.v. when I use it.
They can be set up with a computer and a program that plays on the t.v. so you see the people you are "riding" with and record all the data. Mine is just a simple resistance unit which I can pick up and throw in the closet in a couple seconds.
