Awesome, thanks for the insight – much appreciated!
I notice the prevalence of what I'm calling the "yoga culture" in the urban scene, in which people take part in yoga classes because of social expectations or what have you. It's a lot about getting seen and wearing it like a badge, though this is only my opinion and I don't have any way to back it up. But I just know that's how trends work.
I've been recommended yoga as a way to help alleviate stress and back pain, and I think I'd much rather do so in the comfort of my home where it's just me and I can focus. I have heard that apps are great, but I'm sure that the videos that you've recommended are similar – apps are just a nice way of packaging up videos, but perhaps with an accountability measure though notifications and such.
I think there's always benefit in taking whatever kind of yoga is available, but I as I say I do find standard Western classes to be somewhat superficial.
I hope you will give it a shot and find relief from your pain as quickly as I found relief from mine. Life is much more enjoyable when you're not hurting or stressed all the time! I think there's a big benefit in starting at home, because you can really customize your sesh. If your back is hurting, it makes sense to give it a little extra attention!
You can probably find apps that have special little routines specifically for back pain or for stress relief or whatever.
I hope you feel better than ever super fast!
