A Healthy Spine Needs Adaptability, Not One Perfect Curve

Originally shared in the Nurture Bodyworks newsletter · April 2024

For years in my yoga teaching, I emphasized finding a “just right” lumbar curve and maintaining it as a sign of good alignment. Continued study of biomechanics and Postural Restoration has reshaped that belief.

The spine’s health depends on adaptability, not on preserving one curve in every position. The lumbar spine should be able to extend, but it also needs to flex, rotate, and respond to what the pelvis and ribcage are doing.

Static alignment is not the same as functional alignment

A position that looks ideal while standing may not help us walk, reach, lift, or breathe. Functional alignment changes with the task. It allows the body to organize support while still having somewhere else to go.

The hamstrings and obliques are part of that story. When they coordinate with the diaphragm, they can help bring the pelvis and ribcage into a relationship that gives the spine more movement choices. The goal is not to flatten the back permanently; it is to regain access to positions the body may have stopped using.

This marks a shift from trying to achieve optimal alignment as a single shape toward finding alignment that adapts to each position, movement, and breath.

A healthy spine is not one that never changes. It is one that can change shape, distribute motion, and return without asking the same small area to create every movement.
