When we practice good posture, we keep our bones and joints in the correct alignment. Bad posture is one of the most common causes of back pain.
Correct your posture using these steps.
Check your posture by standing with your heels against a wall. Your calves, buttocks, shoulders, and the back of your head should touch the wall. You should be able to slip your hand behind the small of your back. Now, step forward and stand normally. If your posture changes, correct it right away)
