If you havelow back painor neck pain, then you understand how debilitating this can be.
A visit to your physical therapist is a good first step in caring for your back or neck pain.
Postural correction is also an important component of any physical therapy program for low back or neck pain.

Brett Sears, PT, 2011
A simple exercise to perform to help train your body to recognize proper posture is called theslouch-overcorrect procedure.
To start the slouch-overcorrect exercise, sit in a chair with your back unsupported.
Then, slowly allow your back to slouch down into a forward flexed posture.

Brett Sears, PT, 2011
Your movement into this position should be slow and purposeful.
It is helpful to keep your feet flat on the floor.
The forward curve in your lower back should still be present, just not fully accentuated.
You should now be sitting in proper posture for your back.
