Hey Ben,
Yes, I'm based in the U.S. And you're correct... NSCA = National Strength & Conditioning Association.
Their cPT cert is quality as far as certifications go and their CSCS is the gold standard in this industry right now as far as strength and conditioning for athletes.
Truthfully... this industry is failing in the sense that there aren't rigorous standards for calling oneself a personal trainer. This coming from someone without a degree, mind you. I started a masters in exercise physiology and frankly... it just wasn't doing anything for me.
There are very few barriers to entry in this profession. To boot, any certification, I don't care which... even if it's the best of the best... it's simply the tip of the tip of the iceberg.
The human body is too complex and dynamic to have one certification cover all facets of human body and performance. Which isn't a problem, really. The problem lies in the fact that most so-called professionals stop the learning process as soon as they pass their certification exam.
If you're going to be a truly informed trainer, you should be well versed in biology, physiology, physics (energy, biomechanics, etc), anatomy/kinesiology, chemistry, etc. as well as all the subset sciences that are born from these areas of study.
You're not going to become competent in all these fields simply by reading a certification text book. Frankly, all these texts do are prepare you for passing their exam. That's it.
My background? Truthfully not all that impressive. Two degrees in unaffiliated fields of study. Thankfully, knowledge/education comes by way of multiple paths. The fact I'm a huge nerd and love science didn't hurt. I'd finish my masters if it meant more rigorous standards would be placed on the field. Shit, I'd pay double for the degree if it meant less bozos would find their way into gyms in charge of people's health.
I currently train out of the suburbs of Philadelphia, Pennsylvania. My partner and I own a training center where we train a wide array of individuals. Right now I have a client who is 570 lbs and another looking to increase velocity in his pitch and reduce injury potential so he has better chances of getting picked up by a major university to play ball. Like I said, it's a wide array of people we deal with.
I've been training for the better part of a decade.
If you have any further questions, I'm all ears.
