One of the maladies of excess sitting is poor posture. Another is back pain. Especially while working at a computer, sitting tends to drag one down into bad posture, slumped, with rounded shoulders and head forward with a vulture neck. Such posture is not pretty and it causes back pain. To best accommodate gravity, the spine should be pretty much vertical with the head over the shoulders, not way out front. When you are slumped with forward head parts of the back are weakened, others are overstrained. Pressures on nerves and connective tissues are uneven and exaggerated. Back pain results.
