frederick matthias alexander pioneered a technique over a hundred years ago that improves overall wellness by focusing on physical posture.
known as the alexander technique, it can be summed up by the phrase, "hold your head up".
the more you hold your head up , the more you resonate with everything that holding your head up means.
the simple act of making that shape with your body sends signals to the brain that something is changing externally to allow the head to rise and so we get the feelings of confidence, motivation and physical preparedness as a result. a feed-back, feed-forward mechanism.
i use posture in client sessions to help people know the difference between standing one was and another and helping clients to be more aware of the body shapes they make as a signal to themselves and to others.
do you notice how the way someone carries themselves gives you impressions of how they are inside?
