That’s a great question & such a major can of worms you’re looking to open. Yes, there are many imposters in our field calling themselves “personal trainers.” It’s a good & bad thing that there’s no licensure. The good – there’s nobody telling us how to do our jobs & charging us licensing fees. The bad – anyone can say that they’re a personal trainer regardless of their credentials. But here’s the thing – people who can afford a personal trainer aren’t stupid – they’ll weed out the imposters & hire us who are qualified. I’m with you, I pretty surprised that we don’t have to be licensed – I thought that was coming over 30 years ago!
