Personal Training Sessions: What to do?

I went into the gym the other night and the guy behind the desk asked me if I wanted to save money on my membership. I was skeptical, but he made me an offer I couldn't refuse. So I signed up. With the deal I got I get 5 free one hour personal training sessions. I have no need for a trainer, I'm pretty well versed in excercise science, how to push myself and how to reach my goals. However, I'm always interested in new ideas and could use someone to bounce ideas off of.<br><br>
For those of you that use or have used personal trainers, how does a session usually go? If I give them a rough outline of what I'm doing and what my goals are, do you think they'd be willing to make suggestions as to what I could add or improve? How educated are these people? Are there certain things that they won't be willing to help me with?
