This posture, which consists of a pronounced lower back arch and protruding stomach, is particularly common in people who work in a seated position. If you've ever seen the Disney character Donald Duck, you might be familiar with the posture. In people with an anterior pelvic tilt, the pelvis is tilted forwards, which can drastically affect posture and cause problems in the neck and lower back. Slumped shoulders are a common posture fault in both active and inactive people. Most of the time, this posture is caused by laziness or weakness in the neck and back muscles.
