The 280 commute
A long daily drive is static loading with a vibration component and a slight rotation toward the wheel. Over months it produces a familiar set: tight hip flexors, a low back that compresses, one shoulder held forward, and a neck that aches by the end of the week rather than the end of the day.
The treatment is aimed at the hips and thoracic spine as much as the back itself, because the back is often the loudest structure rather than the responsible one.
