Strength exercise descriptions?

Could anyone suggest a good web site with descriptions of the exercises listed on the log pages. I'm new to resistance training and not sure what some of the named exercises are. Actually, my problem is not so much the listed exercises as my not knowing what some of my exercises are called and the few labels I do have are not in the lists. The exercises, or some that are similar, might be there under different names.

I paid for a session with a trainer at the local YMCA, almost a year ago now, but I was concentrating more on what I had to do than what she called it. It's upper body stuff, mostly on machines and one with dumbells. It's probably time to see a trainer again for a re-evaluation and new routine but I'd still like to learn some names to log more details about what I'm doing.
