If the scale is the only thing you track, you’ll miss the stairs you climb without getting winded now.

A single number is a narrow instrument, and narrow instruments miss almost everything. It cannot register the flight of stairs that stopped costing you anything, the load you can carry to the car now, the sleep that got steadier, the mood on the days you moved. Tracking one figure makes real progress invisible.

Add two measures you can feel rather than read. How many sessions you got to this month. What you can do now that you could not in spring. Let those carry the same weight as anything a device tells you.
