Ahhhh... pertinent theme that you carry through this practice! I'm 66 now and learning to let go of that clinging to what I "should" be able to do... what an āsana "should" look like... ultimately, this is transforming my teaching and practice. And life...!
I adore the instructor’s duration strength…I lost my breath in the middle of the session and muscle crammed, but recommended the lession to anyone who is willing to challenge their body’s(muscle’) limitation.
