Back pain, neck stiffness, tight shoulders, and a constantly tired body have become almost normal in modern life. If you work at a desk, use a laptop or phone for long hours, or sit for most of the day, chances are you already know this discomfort very well.
The real problem is not just sitting. The real problem is sitting for long periods with poor posture, shallow breathing, and very little movement. Over time, this creates muscle imbalances, joint stiffness, weak core muscles, and chronic tension in the spine and neck.
