How to find it lying down

Lie on your back with knees bent. Place your fingertips on the two bony points at the front of your pelvis and your thumbs on your pubic bone. In neutral, those three points sit level with each other.

Tip the pelvis forward and the hip points drop below the pubic bone; tuck it under and they rise above. Neutral is between, and for most people there is a small natural gap under the lower back.

Neutral versus imprint

Imprint is the deliberate flattening of the lower back toward the mat, achieved by a slight posterior pelvic tilt. It is not a corrected version of neutral — it is a different position used for different exercises.

Teachers cue imprint when the exercise loads the trunk beyond what someone can control in neutral. It is a scaling tool, not the goal.

  • Neutral — natural curves preserved, pelvis level
  • Imprint — lower back gently flattened, slight posterior tilt
  • Neutral is the default; imprint is used to scale demand
  • Neither is "correct posture" — both are working positions

Why it matters

Neutral is the position in which the spine tolerates load best and in which the deep stabilisers work most efficiently. Loading a spine outside neutral is not inherently harmful, but doing it repeatedly under spring load is where problems accumulate.

It is also the reference point from which teachers judge everything else. Without it, "your pelvis moved" has no meaning.

It varies between people

Neutral is not one shape. Lumbar curve varies considerably between individuals, and someone with a naturally deeper curve has a larger gap under the lower back in their neutral than someone with a flatter one.

Chasing a standard shape rather than your own neutral is a common and counterproductive error.
