the body's oldest hinge, swiveling you through every dance, sprint, and dramatic exit since birth

means The hipbone is the large, flat bone forming each side of the pelvis, where your thigh meets your torso.

from A plain compound of "hip" and "bone," both ancient English words. "Hip" comes from Old English "hype," a cousin of German "Hüfte," tracing back to a Proto-Germanic root tied to the idea of bending or curving — fitting, for a joint that hinges. "Bone" is the equally old Old English "bān." Two of the language's bedrock words, simply bolted together.
