five vertebrae quietly holding up your entire upper-body rebellion against gravity.

means Relating to the lower back — specifically the region of the spine between the ribs and the pelvis.

from From Latin lumbus, meaning 'loin.' The same root quietly lurks in 'loin' itself (via French) and in 'lumbago,' that ache of the lower back — all of them pointing to the fleshy, weight-bearing stretch just above the hips.
