The problem here is that this train has left the station many years ago. It’s very difficult (almost impossible) and very costly to regulate this industry at this point. There are many reasons why that is and it can’t be analyzed in a short answer. The only way that regulation can happen in our industry is if health insurances add personal training as one of the benefits for those customers of theirs who need it (and there are millions who do). Just like Physical Therapy and massage therapy can be covered by health insurance, so could Personal Training. But in order for the insurances to add trainers into their providers list, these trainers must get licensed by the Federal government on top of their regular certifications. I said federal and not state because this is the easiest, cheapest and fastest way to have this done. Otherwise we will be dealing with multiple regulations that will be required by each state separate.
I’m not fan of big government, but if this was going to work this is the way to do about it. Otherwise there is really no benefit for our industry to get regulated for the simple reason people don’t really care about it. If the price is right and the testimonials are good enough then trainers would be hired by those looking for one. An extra certification or license won’t influence their decision one way or another (unfortunately).
