The spine showing cervical, thoracic and lumbar curves
Previous Next 2 of 9 Your spine's curves

A healthy back has three natural curves:

  • An inward or forward curve at the neck (cervical curve)
  • An outward or backward curve at the upper back (thoracic curve)
  • An inward curve at the lower back (lumbar curve)

Good posture helps maintain these natural curves, while poor posture does the opposite — which can stress muscles, ligaments or bones.
