This video is aimed to help with understanding how a relaxed shoulder feels and can move.
This reminds me of the time when I visited Rick of Wujifa a year ago. He had me get in a zhan zhuang “holding the ball” posture. Rick then put his hand under my elbow and told me to let the elbow relax. He then removed his hand, but my elbow stayed fixed in the current position. Once again, he put his hand under my elbow and told me to let the elbow relax. This time, when he removed his hand, my elbow dropped down.
As Rick let me hold this position for a while, I soon began to feel no strain in my arms and shoulders. It felt as if my arm was floating in the air, effortlessly. I looked at Rick in awe and he just smiled.
