To help us improve our physical fitness, we quantify our physical strength, noting how fast one can run, how long one can jog, how far one can throw a ball, and how much weight one can lift.  The approach of aerobics to physical fitness generally depends on quantifying the aerobic aspect of the exercise.  We quantify physical fitness, and then use the quantified targets in order to improve.
