The best we get is what tae bo is to professional boxing.
Source: conversations and experiences with someone who had the fortune to study both in New Delhi yoga university and with a Yoga lineage in the Himalayas.
The official university still didn’t touch, or know, of essential elements of the practices. Whether intentionally hidden or forgotten, they are completely unheard of in the West.
In the west we have Yoga laptops for heavens sake.
The physical exercises started out as conditioning to be able to sit longer in meditation, which is how you get there.
In the ashram where I stayed we weren't even allowed to talk about the practice.
It’s just a vain feel good activity. Yoga practitioners talk all about their “practice” and improving themselves through their “practice”. You’ll hear yoga studios say stuff like “don’t go to church, just do yoga!”. There’s a bunch of pride wrapped up in getting the poses right, but this doesn’t benefit your body, it just lets you one-up on other people because your pose is “more correct”.
NFL and MLB players do tons of stuff like cupping or wearing magnets that are questionable. Doing yoga because it makes you feel accomplished seems about as harmless as channeling your ego into any sport or physical pursuit.
This is complete cultural appropriation and you should stop perpetuating it while making money off of it.
The problem here is not invention. The problem here is that aliabramovitz and company "like to stay away from those [theological] aspects as it can be off putting for people who don't subscribe to a certain philosophy or theology", in a subject matter where the original theology is a core part of it, and that too a theology that is not aliabramovitz's own theology in order to cater to people who dislike the theology of the original owners of the practice.
So no, white people stealing other peoples practices and bastardizing them !== Invention necessary for the world to progress.
It is simply stealing and removing the original in order to cater to Abrahamics and to make money.
And as an Indian who used to practice Yoga as a child (too boring for me now) I'd say that this is completely fine. If the theological aspect was indeed crucial for deriving value from the whole experience, people would eventually lose interest because they wouldn't be gaining anything from the aliabramovitz's venture right?
Isn't it enough to see that a garden is beautiful without having to believe that there are fairies at the bottom of it too?[1]
[1] Quote by Douglas Adams
And this is the exact reason that these practices should not be divorced from their theological fundamentals in the way that White Abrahamics practice it.
And this is also why you as an Indian should not be happy to let the whole be stripped into parts and sold for money and commoditized down to an entertainment or sport that you are "bored" by.
The implication being that this is the sole purpose of Yoga and there is no benefit in viewing it as yet another point of exercise? A hypothetical:
I have no interest in meditating for long hours, but practicing yoga and the "it helps you calm down" kool-aid that marketers promote actually helps me. It's not the "real thing", and I have an inkling that without the spiritual aspect I am missing out on a lot. However, I continue to practice it since I derive some benefits from doing so, and have no inclination to pursue the matter deeper.
^ I honestly see nothing wrong with the above scenario. I would accept someone who "dabbles" in Yoga without caring for its spiritual aspects the same way I accept someone who lifts weights 5 days a week but completely ignores nutrition. Sub-optimal? Yes. Should it be condemned? No.

That said, I encourage people to read the Bhagavad Gita. As someone who has long appreciated meditation from a secular perspective, I've recently started reading it and am finding it valuable.
In my opinion the result of this type of approach is a diluted, incomplete practice, focused mainly on symptom relief, which tends to forget the heart of the matter.
There is nothing wrong with taking these practices as inspiration to help people, and I think your approach is a good way to bring them to know more about these practices.
But perhaps you should bring a little more of the philosophical/theological side to this modern take on meditation, something like what Stephen Batchelor is doing with his Secular Buddhism.
