Christine: maltifidus

Body: 

In Diana Lee's work for helping post partum mothers recover from pregnancy deals with strengthening the malfidus. The exercises that I did seem like they would be helpful in the back keeping it's nice arch to help the pelvis stay pointed down. But I'm not sure I understand how all of these things are connected. I wondered if you could clarify or if you think that fits with the posture.

The erector spinae and multifidus are both deep muscle groups along the spine that are responsible for extension and rotation. They extend the spine by exerting their forces downward – not pulling up - and are fully extended in the posture.
