But can someone explain to me how core work (without losing weight/fat) could possibly make your waist smaller? Or is it just that OP must have replaced a bit of fat with muscle with her new routine?
If you have a stronger core, it can improve your posture (seated, standing, walking posture, all of it) and also make it easier to engage your abs when you move, even something simple like sitting up or crossing your legs. Even with the same amount of weight, this shift in posture and engagement can make your waist feel narrower and more defined because you will be more lifted and engaged.
I did ballet at a high level in high school and college, including partner work with lifts. Very good core engagement (muscle engagement generally but core engagement is essential) can make a person feel like the weight less. You may have experienced this in picking up a sleeping child (zero muscle engagement) versus a child who is sort of helping you lift them by reaching up and sitting up tall. Core strength and engagement can be transformative for a body.
