I've been lookin around for over a year now on courses to become a personal trainer, and i finally found one that's pretty decent, and now i'm just waiting on the results of passing or not, then i gotta send in and get my certificate. But honestly, pretty much EVERY gym around here, if there's 10 PT's working there, only 2 of them at most are any good. It's SO easy to get your certificate it's unreal.
I ran into an old friend at the gym the other day and we were talkin about how easy it is to get the cert. He told me a guy he went to high school with decided to start working out, and he was taking all kinds of supplements right away, and about 3 or 4 months later, the guy was like "I got my personal training certificate"... think about that. Someone who's VERY new to working out, is a certified personal trainer, and he's in high school...
If your trying to find a decent personal trainer, LOOK AROUND!!! Don't just pick them at random, think of it as shopping, and find out from their clients how their results are coming. And the first sign of a bad personal trainer, in my opinion, is if they are out of shape... unless they've just been through an injury, otherwise, they can't be that motivating either if they can't even motivate themselves to work out.
Good luck in your search.
