Coaches that train sportsmen care about making their sportsmen better. Their success is based on improving their athletes overall performance on the field/courtroom/ring. The End is usually what justifies the means.
Personal training though, you've got everything screwed up. The whole industry wants to talk about how exactly important "results" are. Every ones clients wants outcomes, you are the outcomes delivery people. And how do you do that? You make #%^ up.
Disagree? Run down a mental list of the https://en.search.wordpress.com/?src=organic&q=New Jersey personal trainers you've encountered who use a periodization scheme, who've defined protocols for stability, strength, hypertrophy, and power. Describe your education with Stuart McGills study and Mike Boyles Joint by Joint approach or the last period you examine anything by Verkhoshanky or Yessis or Bondarchuk. Your familiarity with Grey Make and the FMS or Dave Tate and the EliteFTS corporation?
You know who John Goodman is? Thomas Plummer maybe?
"Um, John Goodman is just an actor. I have no idea plumber is, is definitely he an actor too?"
... you sorry sorry fellow.
I can let you know the answer, and its going to be considered a long set of NOs.
None of you know anything. Your "education" starts and ends with your training qualification textbook that you hardly ever read. Your "workout routines" are whatever the hell you found on YouTube that looked hard. Your own training is the stuff you prefer, and you've neither obtained significant lean mass nor improved your athleticism in the last 10 years. You became a trainer because you "liked training and employed in a fitness center seemed easy", and that's a direct quote incidentally.
Everyone reading this is going to swear they are not this sort of trainer, but they can say for certain at least twelve trainers that suit this description flawlessly though.
You'll argue that you do know your stuff though. Your argument will be based on the fact that you clients tell you that "you're my shrink/psychologist/life coach". You'll eat that junk up and believe that you're amazing because you know the condition of everyone's marriage. Then you'll argue that their spending money on assistance because they're unhappy and its your job to create them happy.
Boy oh boy it is. Its also your task to obtain BMI below 30 and lower their risk elements that come with being a deconditioned fatass. That's your first job. That's what they hired you for, lest you neglect.
"All my customers get results though!! Except the types that don't and stop after their starter package or tell me they cant afford teaching."
That makes a whole lot of sense. After all, obesity carries with it no higher health care costs over the course of a person's existence. Neither does seated 10 hours a day, eating a diet plan of Costcos frozen meals, and implanting your ass to your sofa. Those ideas all lead to https://zenwriting.net/s7yokao412/iframe-src-www-youtube-com-embed-plgawiqff90-width-560-height-315 happy existence and in no way is a heart attack of type II diabetes in your future.
So what types of system is your schooling based around?
Don't solution, because that probably simply confused the hell away you. And please god don't say you're P90X certified. JUST, DON'T, SAY IT
We tire of encountering trainers that boast of their results based schooling principles, but have no system for producing stronger/skinnier/fiter clients beyond the program they pulled away of their certifications text book/FLEX magazine/bodybuilding.com. This drives me bloody crazy.
And to answer fully the question "whatever your qualification textbook/mens wellness/bodybuilding.com/form magazine said" is just about the answer.
That's lovely, it really is. I'm glad that people who entrusted you with their health are being qualified using workout routines of the week from Bodyrock Television. (on a side take note, I'd worship that girl's body till I collapsed by from exhaustion and dehydration, but I digress).
Ive heard arguments against trainers periodizing their customers training. Ive heard arguments that most fitness workouts don't care about the program, they just want to enjoy the workout.

Ive read all of this, and then I shop around at a US people that is 2/3rds over weight, 1 in 4 are obese, and the prevalence of low back discomfort, joint issues, and a generally inability to go is rampant.
And fitness trainers don't want to follow any kind of progressive programming scheme, since the client might get bored.
So I'm calling out the whole fitness industry then. That is utter ridiculousness, and you all understand it. Lucky for you if you train nothing but hypermotivated athletes and versions. Those aren't the training market for the next decade though, the 100 million those who are overweight are the market.
These people will require a progressive system for ridding their bodies of this excess bodyfat. They will have to understand the difference between bodyfat and lean mass. You will need to know about hormones and how their insulin sensitivity is totally fucked up.
You'll need a system to restore normal joint mobility. You will have to find out about fascial patterns and higher and lower cross syndrome and movement engrams and imbalances and how exactly to fix these things.
You will need to know about nutrition and be able to make coaching advisements that border on being truly a psychological prescription to improve.
You'll need to be able to progress someone through defined stages of training that encompass joint stabilization and mobilization, that encompass the essential movement patterns of squat hinge pull press push. You will have to teach them why these things are important.
And you'll need to do this for old people too, because geriatrics are overweight too and seniors are just getting older and more immobile.
You'll need a system for each one of these points. A teachable, defined system.
And you'll need all of the education that comes along with it.
Therefore get smarter dammit. And if all of this sounds unappealing, then get the hell out of this industry. I'm fed up with personal training being regarded as a joke job that's done by college students and exercise addicts.
Were medical researchers, and we need to become it. And the majority of all, we need to BACK IT UP.
