Want to sit with better posture? Yes, good move, as this influences your body’s afferent nerve input (signals that go to the brain from the body), thereby affecting how you feel!
Here are the 5 corrective movements:
1. Tilt the pelvis forward
2. Use your upper abs to flex the back
3. Raise the sternum up
4. Use your neck flexors to tuck back
5. Shift your gaze forward

Let me unpack these if you like the detail…
1. Anterior pelvic tilt. Sit with the feet flat, if on a firm chair, you may feel your ‘sitting bones’ on the surface. Tilt the pelvis which is the ilium and sacrum bones forward SLIGHTLY. This is to ‘create a bit of space or elongation at the lower back’ (not compression).
2. Upper ab activation- these muscles when contracting flex the upper lumbar / lower thoracic spine. Keeps the lower anterior ribs from ‘flaring out’. Every movement teacher’s nightmare. And for good reason, it is straying from neutrality, over compressing thoraco-lumbar vertebral joints, which then often leads to a chin up posture, disadvantages the deep neck flexors, and subsequently compressing the upper neck joints.
3. Simply raise the sternum, which provides extension of the mid thoracic vertebral joints. A good thing. The opposite of what happens when your head is in the screen. You don't want this...

4. Neck flexors engage to flex the cervical spine, leading to a chin down direction. The deep neck flexors (DNF’s) subtly do this, which brings the chin down ½ an inch, thereby making space at the upper cervical spine joints. When doing this, think about the chin going down AND the head being pulled back and up, making you taller.
5. Finally, the cherry on top… look straight ahead (over that typical computer screen set up perhaps!) and breathe. Spinal extension does facilitate breathing in, so this may happen naturally! Imagine hinging ever so slightly from the occipital region joints.
