That one gets filed in my favorites. Felt therapeutic for my very tight shoulder, in all the ways that are challenging but good. I particularly loved the "teacup" move from qi gong (balancing the block like a platter while moving)... that's one of my favorite movement patterns anyways, and so interesting with the block addition.
Oh my goodness, what a lovely quiet, yet strengthening practice this was! I love this one. I'm so glad I found it. My waist perked up as did my shoulders. I'm so glad I did this one and I'm saving it now.
