After the 2-days Hong Kong Chen style Taiji practical method workshop held on 17&18 Dec, I joined the regular foundation Sunday class. Starting from my 1st day training, I learned the importance of the kua opening. When doing twist-towel or fetch water foundation, by opening the Kua, power can be transferred from the foot (ground) to the hand.
In order to see my measurable improvement, I measured the distance between my knees of my stretched open Kua on the 1st day. With the training aids of rubber band and rubber block, I practice the foundation exercise at home everyday. Today just finished the 3rd training lesson and I measured my knees distance again. I have little improvement from 80 cm to 81cm. I understood that this is very difficult to get my kua open at my age of over 60. But nevertheless, I will keep on trying.
I got one extra bonus, my waist get smaller, from 88 cm down to 85 cm.
