Has your relationship with your body composition shifted after 45?

I've noticed that what I'm aiming for has changed over the years — less about a number on the scale and more about how I feel, how I move, and whether I feel strong. But I also won't pretend I never struggle with the changes that come with this stage of life. I'm curious whether others have found a way to care about body composition without it taking over their headspace. What does a kind, sustainable approach actually look like for you day to day?
