The idea behind the show, supposedly, is that it's an exercise anime, where you do exercises along with the characters. However, the actual show puts the camera at angles that make it clear the actual goal is to be pure fanservice.
It's not really the fact that fanservice is involved that bugs me (because of course there was going to be fanservice when you have cute anime girls) so much as that this comes at the cost of actually being an exercise show. The camera angles and pace are not beneficial for someone trying to follow along.
In the end, I'm not sure if Anitore! EX was an idea that got destroyed by producers who said "more cute girls" or if it was always going to be cute girl trash that decided to use bait and switch advertising to appeal to a wider audience. Either way, the final result is pretty darn useless.
