What’s A Neutral Posture?
Let’s start with a small experiment. Sit on a normal chair, and then on a very low chair or on the ground. Do you feel a difference in your hip joint? On the low chair, it feels tight, compressed, and even painful after a short while – this is called a closed posture. There is great pressure from one bone against the other. Hence, the cartilage wears off quicker, and all the tissues (muscle tissues included) are more tense.
This is why ergonomists develop all kinds of methods and approaches to promote neutral postures, for all different body shapes and sizes.
