Appearance can distract you from asking whether your body actually performs well.

Looking a certain way and functioning well are related but far from identical, and the visible one gets almost all the attention. You can spend years optimising appearance while stamina, strength, sleep, and joint health quietly decline, because nothing in the mirror reports on any of that. The measure you choose determines what you actually build.

Add a few functional tests to how you assess yourself. How you feel on stairs, how well you sleep, how quickly you recover. Let those, rather than the mirror, guide what you train.
