What works:
1. having a lecture on a chalkboard
2. taking notes by hand. Yes, by hand. Something about the act of writing it by hand fixes it in my brain
3. using pencil and paper to do the problems.
4. and what really works is giving an in-person lecture on how to do it
What doesn't work:
1. everything else
I've watched many instructional videos. Poof, none of it sticks. I've audited classes. Poof, none of it sticks, because I didn't do the homework.
I've never known anyone who learned arithmetic from a calculator.
It's like wanting to be strong. You have to do the work to get strong. There is no substitute.
There are visual learners out there. Being a visual learner doesn't mean you don't need to do the work, it means you typically need some visualization for things to click, and then you practice applying it like everyone else. Some people can even manage with just lectures.
This causes some students trouble in school because their needs may not be met by every teacher. It's especially worse if the student hasn't learned what their learning style is yet.
Learning Styles: VAK Doesn't Exist (Here's What Research Actually Shows)

Belief in Learning Styles Myth May Be Detrimental (by American Psychological Association)

I have difficulty believing that my learning style is uncommon. Consider trying to build muscle. There are techniques that are proven to work best. There are no individual "muscle building styles" that work better, unless the person has a disability.
And I don't believe that in general the kids in classes are mentally disabled.
Yes, I know about ADHD, autism, and dyslexia.
I think it's more of a motivation problem. Not all students are eager to learn. They may not be interested in the subject for whatever reason. It's hard to teach someone who isn't open to it. Learning styles can help bring some of those barriers down by shifting the material into a form that they are more open to.
The same applies to building muscle. Not everyone is self-motivated to do it. There are different ways to motivate people to work out. But in the end they all need to do the work/practice.
You have to do the exercises. But it might be beyond your ability to start doing them straight from the textbook. Crafted didactic material can walk you through initial exercises to the point where you have a theory of where to begin on another one. Or it can let you investigate a structure until you have an idea.
In your analogy, if you want to be able to bench 150 pounds, at some point you'll have to bench 150 pounds. But a nonconfigurable 150 pound weight isn't the best way to get there. You can have a set of weights that let you start with easier tasks. You can have a set of exercises that aren't bench pressing. Those things are helpful, and generally required.
The real problem beyond all this is that the educational spending goes to the wrong spots. If you ask me, teachers should be empowered to select their own curriculum using a budget and most of the rest of the money should go towards paid tutors, better teacher-student ratios, etc (and probably way fewer administrators). I am firmly convinced that a lot of kids act out because they can’t grasp the material, not in spite of it.
