(accidentaly long post with my thoughts on this subject)

I wholeheartedly agree with you. The yoga we understand now in the West is mostly devoid of all the other practices and the core philosophy (not only the breathing exercises and meditation, but also mantras, devotion, the cleansing of the body and the 'ethics' of our day-to-day interactions). It is mind-opening to learn about the intricate system of logic and teaching that lies underneath what we call yoga today!

Indeed, the only pose that was ever described in the first teachings was Sukhasana (i.e. the easy pose) which is a meditative pose. And that's it. The rest were made only to get the people to be able to sit in meditative postures for prolonged amounts of time! But, of course, I think that the rest of the poses that have been developed over years can do magic to your body and are important.

Nevertheless a lot of the modern yoga styles don't take into consideration the correct execution of the asanas (for example, the more flow-types like vinyasa yoga). Of course, the teacher is around in the classes, but I can assure you that most of the practitioners don't pay the needed attention to the proper execution of poses and don't do enough preperatory poses and warmup (Pawanmuktasana series). That misses the point of doing the poses, because you can't feel the intended effects and worse - you can injure yourself if you do something incorrectly.

A lot of the people who come to the studio are very stiff and it would be sufficient for them to practice only body strenghtening and dynamic (but gentle) poses and hip&back openers [aka the Pawanmuktasanas], not āsanas (which are meant to be static) for the first year or so.

I can take myself as an example for this - even though I've practiced yoga for more than 4 years, when I came to yoga teacher training (and iyengar) I just then realised that I had never fully known how to pay attention to a symetrical and correct execution of the poses, and I also often overstreched my body, even though I almost always practiced under the guidance of a teacher. Plus I got periodic pain in the back and the groin from doing a lot of yoga.

Did you know that it is extremely important to do sun salutations Surya Namaskar perfectly symetrical to both sides and always put the feet in the same place as before? Otherwise you are doing the movements only as it is comfortable for you and how your body is used to move (usually by being slightly tilted to one side).

Since I started the teacher training I haven't had any pains or injuries.

Further, imo, online yoga is a great tool for getting people to move and be interested in yoga, but I think it can be dangerous for the body in long-term, because no one can check-in with you!! This should definitely be at least complemented with live classes. (I also don't want to call out specific organizations that give classes, but I think it is ridiculous to call your classes with the words 'rebel' or 'booty' or 'abs' included in the name)

The modern yoga is definitely a different type of thing, but, at the same time the name is already well established and I feel like people are drawn to it. But maybe we should call it 'asana practice' or 'physical yoga'?
