What are the best yoga poses to correct before head posture?
I have terrible head forward, like this: http://www.proposture.com/images/girl_lg.jpg and I want to correct. What are good poses (and posture improved overall as well?) I know cats and cows are good, but what else? Sonya, Thank you. Children pose is one of the favorites is a pleasure for me. 
Thanks Siri!
You need to practice lock neck to improve this position. Try sitting with your chin a little and your chest and heart a little advanced. Do not tilt head forward and keep your muscles relaxed in the face.
