gumby, I would have been annoyed and amazed too with her dopey comment.
If you're interested in doing exercises on your own, I have a fantastic site that I use.
Here's a link for an exercise and muscle directory-www.exrx.net/Lists/Directory.html
The left window pane displays the exercises that are done for the muscles listed in the right window pane.
There are animated gifs to show how the exercise should be done. It really is an excellent site.
Here is the home page that is filled with plenty of information-exrx.net
On the left you'll see a menu with great information such as beginner's page that lists ways of stretching out, diets, Etc.
