I am literally clueless about yoga, never done a session in my life. Can someone give a completely unbiased opinion on her yoga? She surely to
God cannot be as bad as people say
What I will say is: yoga is not super easy and it looks different on absolutely everyone's body.
She is doing that position from the photograph shared completely wrong, her hips should be level and if I was teaching her I would be adjusting her or advising her to remain in downdog for now or not raising her leg as high until she can self correct it.
I still make plenty of mistakes doing yoga after years, your body has movement patterns which it learns/develops and will naturally do "what's easy" for it unless you challenge it, but it's about acknowledging and using props to support you, making a change to the pose. There's day I can't do warrior poses without my knee tracking inwards and I have to just accept in order to really be in and feel the pose I need to use a prop.
I think Shivs issue is she has a phenomenal sense of pride and ego around her yoga practice and you really can't have that attitude on the mat, you have to accept you will make mistakes, your yoga will not always be perfect or look right, etc. it doesn't mean you should stop or not practice until you can do it right it just means you need to be mindful and keep you and your body safe.
I'd have no issue with her teaching poses as, like I said, sometimes I don't do it right myself (!) but being able to talk other people through it, advise and guide them through the poses and not have an ego you're solid.
I wouldn't like anyone to be put off trying yoga by people saying Shivvers is all wrong, your practice is your practice I would always advise going to a few in person classes (for the social as well as the benefits of having a teacher available to watch you), but becoming a teacher is a different kettle of fish and I wouldn't advise anyone to become a teacher after only ever practicing online and attempting the teacher training online previously.
