When you sit for hours a day, your pelvis and spine get stuck in the sitting position as the muscles that are unused atrophy and muscles that are contracted during sitting shorten. This gives you an imbalanced pelvis and spine position that force your head, and shoulders forward and tilts your pelvis when you stand up. Then you spend your non-sitting time walking around with a fucked up posture, which only makes it worse and gives you back and joint problems, poor circulation, and increases likelihood of injury from basic tasks.
