If you would like to to teach soemtime, maybe it’s time to sign up for a yoga teacher training course. The course im on is amazing, it’s a dimploma course at an ashram and is accredited with the British Wheel of Yoga. We don’t just cover teaching yoga and anataomy & physiology (which is amazing), but personal development through doing the practices and doing things like Jala Neti and the like.
I was in a similar position to you, wanted to know more about the body, my limits and was wanting to learn to teach so I could share yoga with friends and family.
Good luck with what ever you do.
That Structural Yoga books looks fab, it’s on my amazon wish list now, but I wont’buy it yet, I need to see how the course pans out.
The Pawanmuktasana - Part I is a good overall joint freeing and strengthenging series, so if you want some variety maybe this is worth a try. This is details in Asana Pranyama Bandha & Mudra (Bihar School)
All the best
