Anyone have info on becoming a cert. personal trainer?

[BeenHereB4]

Looking to do some training from home for the test to become a certified personal trainer. Seems to be some demand for it in my area and I'm no stranger to the gym, running, etc. I think it would be a nice job for me even if I only had 2 or 3 clients a week.

I'm looking for info from anyone who has used a successful (or not successful) program and passed the test. Also any experiences with the job.

Thanks so much!!!
