Tried 供天、PJHS and GYFM last night. Don’t know whether I did correctly. Anyway, true enough, I felt quite restless after about 10 mins into GYFM. A bit hard to sustain.

Moreover, I experienced backaches during the process. The aching feeling felt like I just ran 2.4km. 很酸。Cannot take it. Went to sleep. Then, I felt sharp pain at my 雪山 area, around the tailbone. 酸痛的感觉。Why is it like that? 😦
