Should I expect a yoga class to actually teach me how to do yoga?
I've gone to a couple of yoga classes at my gym (Yin and Vinyasa), and I'm continually bewildered by what I'm supposed to be doing. The instructor in the first class didn't interact with me at all, and the instructor in the second class made one small correction to a pose. I'm just trying desperately to figure out what I'm supposed to be doing, and half the time when I look up, the other students are in a pose significantly different than mine. Most of the poses are painful, but that could be because I'm doing the wrong movement, or I'm overusing certain body parts due to fatigue, or just because I lack the flexibility to do them correctly. Despite the fact that I'm obviously just flopping around like a fish, it doesn't seem like there's much in the way of actual instruction.
I've tried to follow along with a few yoga videos at home to learn the poses, but it's very frustrating not to have any idea if I'm doing the movements correctly. I tried to video myself and compare my poses what the instructors are doing, but their level of flexibility and body control is so far above mine that I'm usually not physically able to make my body look like theirs.
When I've done other types of group exercise, there was usually at least some portion of the class that was devoted to actual instruction. In a jiujitsu class, the instructor will typically show you a technique, and then you practice that technique, with feedback from other students and from the instructor. In a Crossfit class, they show you the movements you're expected to perform, and there are generally scaling options to make every movement fairly beginner friendly.
Is there anything like this for yoga? I'm very discouraged by the idea that I will need to study and practice a bunch of movements, and then figure out the appropriate scaling options for my level of flexibility and advancement, before I'm even ready to take a class.
