If you have any pressure on your joints then you are creating a downward pull to the Earth.
if you come across a teacher of the Alexander Technique, ask them to grab a chair and show you whilst standing and sitting how to drop your weight to the Earth to allow the wonderful upthrust of release of pressure that accompanies an Alexander experience.
Your body is gently bought into an improved balance which allows this to happen.
Us humans have a problem: How can we stay balanced on two feet without getting tense? Without pulling back our shoulders and bracing our knees?
We have a fundamental requirement to achieve balance, yet the cost can be high in wear and tear on body parts and excess muscle tension.
This is where The Alexander Technique comes in, rebalancing overall muscle tone to dynamically support the skeleton, reducing stress on all the joints, big and small, and freeing up the ribcage.
People do not decide their futures; they decide their habits and their habits decide their futures.
