I first want to say that I've always kind of been skeptical of most personal trainers because of the perceived cookie cutter, by the book stuff that many tend to follow. I know that there are better and more efficient ways to train, but I think that getting the certification as a personal trainer could be a very valuable tool. My buddy is getting his personal trainer certification this summer through ISSA, but I've been looking around at other programs like NASM, NSCA, ACSM, etc. I just want to know others' opinions on what would be the best program. Factors to consider would be gained functional knowledge as well as respectability of the program. I want to see what would probably give me the best opportunities.
