Thanks for all the info everyone. I don't mean to sound like a jerk but how difficult is it to stand motionless holding your arms out?
I really don't see the necessity of having a qualified instructor overseeing that type of training.
I just don't subscribe to the notion that all is hopeless without personal instruction from a qualified teacher. Results vary depending on the source with personal instruction at the top and scribbled notes at the bottom.
Anyhow I had been planning on trying 20 - 30 minutes of Zhan Zhuang for quite awhile now. Got some good info from Master Wang Rengang in NY.
Sorry FT, I just tried it and all I feel is warmer when hands are close and cooler when far apart. Nothing unusual there.
What happens in Gong Sao stays in Gong Sao.
