There are a ton of instances of this sort of thing happening but the basic gist of it goes like this: Someone with millions of IG, FB, Twitter, or TT followers that is in the fitness industry will have some sort of offer that will often go for hundreds of dollars and in return you are meant to get personalized diet and fitness programs that are designed specifically for you.
This is basically the services that a real live personal trainer would offer but at a fraction of the cost. Sounds pretty great doesn't it? Well it might be if it were true but that is not what ends up happening most of the time.
When you sign up with a personal trainer, which I think is a great idea if you have the money for it and the trainer has good references and proof of past results, you truly do end up getting personal attention because you are there one on one with the trainer who if they are worth their salt, they can detect problems in your diet and exercise regimen as well as spot fix problems in your form in whatever weight training you are doing.
Someone on the internet thousands of miles away from where you are at the time cannot possibly do this.
In a somewhat recent but not isolated incident an influencer named Brittney Davis was sued by the state for selling personalized diet and fitness plans but then simply copy and pasted most of them to a great many hapless saps who paid $90 - $300 each for the plans. She, like many other influencers who claim they will be with you "every step of the way" simply made videos that were exactly the same for each of the customers and was creatively edited so that she would have one part of the video that would say the person's name in order to make them think that it was made just for them, when anyone who looks at it can see that this is exactly what the trick was.

Also another big surprise surprise aspect of the entire thing incorporated purchasing certain special supplemental drinks and powders that she is sponsored by. What an amazing coincidence huh? So not only were her clients paying for personalized treatment that they didn't receive but they were also getting double-duped into purchasing junk pseudo-science supplements that do nothing and cost a fortune.
Brittney is just another very good looking person who works our very hard in her own life and probably has a very dedicated diet plan. I am quite certain that she would be an amazing personal trainer and could demand quite a hefty fee for her services in one-on-one situations. The reality of this is that Brittney and many others like her realize that they can make substantially more money by giving just a little bit of assistance to hundreds of thousands of people all at once.
Brittney got busted and sued, but there are hundreds, probably thousands of other influencers out there that do not get caught.
I do not believe that it is even possible for a trainer to effectively give you personalized information about your diet and exercise in an online fashion, let alone someone who is promising this to tens of thousands of people all at once. There simply isn't enough time in the day for this to possibly happen.
If you can afford a personal trainer then go ahead and get one, at least for a little while to show you the ropes. If you cannot, then do not throw your money away on more bogus crap like this online. I can't find any reputable online personalized fitness program that has been effective for anyone. If you know differently than please do let me know but I can assure you a vast majority of them, especially the ones like Brittney's that ended up getting a lot of attention globally, are not actually personalizing anything for you at all.
