We practiced one knee up one knee down movement. The move after second Flash the back and before going into the jump.
It is the knee movements caused the kua to open, creating a hole which allows the torso to fall straight down.
The going down motion and the torso rotation are one move. The torso is passively dropping. The hands do not move, and the arms are adjusting accordingly.
Some common mistakes:
– The torso is stiff and reluctant to fall.
– The torso has its own movements, like rotating more than what is caused by the knees and kua.
– Protrusion of the hips because of the kua is not open.
– Lean to one side because one kua is more open than the other.
– The knee is pulled down towards the ground because the kua is stuck.
We also went through the details of Second closing. I was not locking the L shoulder-kua line on the rotation. Was only focusing on turning from my waist.
