If your back feels tight after sitting all day, or your shoulders start to ache by the afternoon, you’re not alone. These symptoms usually build gradually. Sitting feels fine at first, but over time, stiffness, tension, or discomfort becomes part of your daily routine.
At some point, you start wondering if posture has something to do with it. In many cases, it does.
Poor posture doesn’t just “look bad.” It changes how your body handles load, movement, and muscle activity. Over time, that can lead to real strain on the spine and surrounding tissues.
