Why does posture matter?
How poor posture affects your muscles
Your head weighs about 10 pounds. When you slouch your head moves forward. This causes your back muscles to work harder to hold your head upright. Some of these muscles are in your neck and shoulders but others attach into your low back. If this continues to happen, over time these muscles can start creating localized pain or can refer to other areas of your body including your low back, shoulders and arms.
