Vash's post has me thinking.

Lately I've been thinking about becoming a certified personal trainer. I'm really concerned about the obesity problem in this country especially in children. I would eventually like to start children's fitness programs in the city that I live and was thinking that becoming a certifed personal trainer would be a good first step.

Are there any trainers out there? What certification would you consider to be most reputable?

Any suggested reading as I begin my quest?

Any thoughts?
