We get a lot of people doing their practical placement at the gym. I give them good advice, most look over my shoulder at the hot chick or guy across the room instead, or examine their nails. I've personally supervised the placements of about 30 students, there were only 3 who I trusted to do a health consult or programme showthrough, most were clueless and not very interested in what was happening around them. One of the ones who paid attention is now working at our gym, I'm not aware of any of the others being employed anywhere. This is a normal ratio, in a class of 20 you'll find 1, if you're lucky 2, actually go on to jobs in the industry. Most people doing the courses just don't know what they want to do, almost none have ever hired a trainer, etc.
In fact recently that has been my first question to the work placement students, and it will be my first question to people asking here about becoming a PT.
"Have you ever hired a personal trainer? or even got a programme from a gym instructor?"
In most cases the answer is "No, PT is expensive, and a programme, well the instructors at my gym are idiots."
"Right... so you think it's not worth paying for personal training, yet you expect other people to pay for personal training with you? You don't trust the expertise of people who've been doing this for years, but you expect other people to trust your expertise? Do you think PT has value, or not?"
It's okay if you don't think it's worth paying for something. I know guys who never pay for a haircut, they just buy electric clippers and get a #2 all over. But these guys aren't trying to become hairdressers. If you don't value what you're offering, why should anyone else?
