I'm sure I'll pay a penalty for so much Yin and so little conventional practice, but in the long term this will pay off.
So many sessions have a surprise. Tonight I really focused while doing a seated hamstring stretch. Unexpectedly, I got a brief massage of my upper back. Damned if my hamstrings did not relax.
It was the biggest single release of my hamstrings I've ever encountered. They have been a problem ever since highschool. Is there a connection that is not obvious? Or, was it the effect of deep focus and then sudden, unprepared focus on the upper back.
For sure, good hands were a big factor.
