The definition of posture according to Miriam Webster is "the position of the body when seated or standing".
While this definition is very vague, your posture weather you like it or not affects your attitude, performance, and the perceptions other people have of you. The positions you hold your spine through daily life are the basis for optimal movement of the whole body. Awareness of keeping proper spinal curves through daily life will create the healthy habit of optimal nervous function.
