What's the purpose of the form/style of Acker's essay?

I believe Acker chooses her style in this essay to mirror the topic she is writing about. The essays form is rather choppy and a bit random, but at the same time it is separated into headings and sectioned off by quotes and topics. The gym is similar. If you try to watch someone else workout at the gym, his or her actions seem random. They use each machine at random, they do random repetitions, they lift random weight sizes. However, to the person doing the workout there is very much a schedule to be followed. Maybe not a written schedule, although sometimes it is written, but often a mental schedule. A routine each individual plans out in advance.
