Basically, anyone can educate themselves on the same shit personal trainers know. It's just a matter of whether or not you need someone to make you work out harder.
I don't even put a lot of trust in what they know. Just today at LA Fitness, I was at the squat rack -- to my right was a trainer with 3 fat ass clients. He had them all on a mat doing crunches and all of this elaborate core stuff. Even a dumbass like me knows those fatties should be doing some cardio.
They don't need a trainer for that.
