Thank you for reading!
Using our midline anatomy as the reference for body alignment and balance seems obvious. (there's far to much focus on the spine and joints IMHO - it's muscles and connective tissues that position our bones, that create and alter our posture).
If the linea alba and nuchal and supraspinous ligaments can be aligned on the median plane the body is balanced. The body needs a full range of natural movement in order to achieve this and not many people have that! Physical restrictions in connective tissues (as a response to to trauma, stress, inflammation etc.) reduce range of movement and cause misalignment and imbalance = pain and tensions, body-wide effects over time. Stored trauma on the body, that can be released by focusing on using the right muscles to work towards alignment and balance.
