I recently took and happily completed the July 2020 Live Yin Yoga TTC (in YI) and have been revising the different practices.
An interesting one for me is the Daily Practice Section 3: Human Variation.
Focusing on the hips and trying to understand the differences in bone shape and structure, I have a few questions:
1. Child Pose: When bending forward and reaching a point of compression, if knees have to be much wider than hips to avoid the pinching sensation, this seems to be transformed into Frog pose. How to differentiate and explain to students?
2. In frog pose (knees very wide and toes touching) I experience numbness / tingling down my calves and feet and this feeling goes away if I lift my hips to bring them in line with my knees and separate the feet like in an attempt to bring my pubic bone down to the floor (even though I don't have the bones for that). What are the nerves being affected? And what would be the implications of observing the sensation but not changing the posture?
3. During the lectures you mentioned a study about the relation between longevity and the ability to stand up and sit down (on the floor) using only 2 limbs. Where can I find more details or read the full study? And what were the main considerations towards the anatomical differences of the hips?
I am very curious as my external rotation is very limited and so far is impossible for me to get up and sit down as you did over again during the course just crossing the feet and being at ease with the hips.
Your comments on mobility and anatomy would be highly appreciated.
Thanks in advance!!
