I'd never worked out in my life. So, I visited many gyms, found a mom & pop, and hired the trainer free from corporate constraints.
My second session he said, "You might be better off doing bodyweight exercises at home for a few weeks."
I told him that there was absolutely no way I'd form this habit by myself. I needed him to hold me accountable. I needed a routine.
We did bodyweight exercises at the gym for a few weeks. We set goals of a certain number of push ups, (band assisted) pull ups, sit ups, and (I forgot the name of the hamstring exercise) to "earn" my way back to the machines and free weights.
I can definitely understand how a trainer could get frustrated with an individual. But, a trainer that sends a noob home simply sucks. They should at least provide a referral to another trainer.
Fitness instructors are people, some can easily be like that - why not? There are people who suck at their job in every field. But given the heroin ending, hopefully this is fake.
Get tired? No, get a sense of sorrow in professional failure and apathy when someone's level of ability is fundamentally misaligned to the class.m, hell yes.
I'm an adult educator, so while not a fitness instructor, I teach adults life skills, including health and nutrition.
We aren't paid to be individual tutors, but the fact is that some learners need one on one training, or additional time, or a slower pace, or a totally customised syllabus and resource package for their needs.
There's nothing tiring about this.
But there's also nothing we can do. You learn quickly in this job to say "I recommend a more entry level class, or starting with a some home learning" or you burn out trying to juggle 25 different levels of need in a class of 25.
Someone, who ridicules people for some characteristic while they are in the process of improving that characteristic, has understood so little about life.
This is why I wish I had a fortune teller to say exactly when I am going to die. If you knew you were going to go out on a certain date, you could abuse opiates for months before your body gets used to them and then avoid the eventual darkness of deep addiction.
