Does any know about the personal trainer program through AFAA. If so what is your opinion about the course?

I am certified with ACE and AFAA. I look at AFAA as a good starting point, but in no way is it a comprehensive training program. I do not feel it is a rigorous enough program. It is certainly not as highly valued as certifications by ACE or ASCM, and I think there is good reason for that. There is no way you can be prepared in a weekend certification. As I said, it is a good place to start, but you should only consider it a first step and continue your education.
