Students started to feel pain and ache. My right knee was in slight pain yesterday, but it was better this morning. I think I was twisting it too much. I will maintain higher posture and be conscious of it till it gets stronger.
I am learning a lot the past week, and had done more yilus in a week here than in five months since I started.
In yilu, hand can not lift, it has to rotate so lever is longer. Lifting only uses short arm.
In punch to ground then kick, have to rotate on left ankle, keep body weight on left foot. so turn left ankle in first, then rotate.
