Yes, I have watched people talk on their cellphone while working with a client. I’ve watched people not even watching the client and looking bored out of their mind. I have watched trainers make the absolute worst exercise choices for clients (overloading too much or too complicated.)
I’ve been in clubs where it was encouraged to over-push people and I wouldn’t do it. I’ve been in clubs where I’ve seen really great trainers as well. The profession has a lot of turn over, many people think it’s an easy job and decide they can do it. They have no idea how much work it is.
The bad thing is, it’s hard to erase a person’s bad experience with a trainer, making people not want to use another trainer, or maybe not continue exercising.
