In the movie Princess Dairies there is a scene where Mia, played by Anne Hathaway, is practicing good posture with a book on her head and walking across the room. 
Although books are not required, good posture is important in preventing lower back pain. 

 

This spine wellness tip will highlight how to evaluate your posture. 

  1. Stand with your heels against the wall.
  2. Your head, shoulders, calves and buttocks should be touching the wall. (Once you do this, you should be able to place your hand behind the small of your back).
  3. Now, take a step forward – this is how your posture should be.
