I worked in the fitness industry for roughly 7 years (5 of which I was a Certified Personal Trainer). I have had the opportunity to work in non-profit, corporate, commercial, and even ran my own gig training soccer teams and individual athletes for a couple of years.
I have met an insane amount of trainers during that time whether it be from conferences, coworkers, or someone I meet when I visit a new gym. I must say there are plenty of high quality trainers that know FAR more than I ever did/will about personal training, the human body, and nutrition. However, I have also met plenty of bad trainers who do things that are so counterintuitive to typical personal training norms.
Also, little known fact: In the USA you do not need to be a certified personal trainer in order to work for a gym and train clients. In addition to that, there are so many non-accredited personal training certifications running around out there that have an online test with no proctors and unlimited retakes at no extra cost. It's wild haha!
What have your experiences been like?
