releasing the psoas

Body: 

Liz Koch has a chapter in her book about 'Releasing the Psoas'. I was thinking - standing in WW posture is an automatic releasing of the psoas right?

Hi, I just bought this book after reading your post. I think this is my problem and it relates to childhood conditioning...I think that it requires multiple actions- body posture, exercises, my PT sessions and psychotherapy...As my PT said my muscles are just so tight! I have been much better, but still experiencing set backs.

Reason I asked is because when I followed her instructions for releasing the psoas, I felt as though mine was already released so to speak, as a result of ww work. She had an article in the Village News a few months back I think.
