John Upshaw created a challenge for himself to do 600 fetch water (300 on each side) from Jan 12, 2019 to July 24, 2019 to focus on opening the kua before the North American Training Camp 2019. A few of Master Chen Zhonghua's disciples, including myself, and students supported him and joined the challenge. My students from the weekday morning practice also joined in the fun.
Jan 13, 2019: I am also using the rubber cord to do fetch water on some days.
Jan 26, 2019: Two weeks into the challenge, I noticed that my chest and abdomen muscles became more developed. They felt tighter.
