You sometimes notice your body feeling less heavy before you actually lose weight, right?

My weight hasn't changed much, but
I have often heard people say that their bodies feel a little lighter when they move compared to before.

Like when climbing stairs or standing up after sitting for a long time
Could changes that are difficult to verify on a scale sometimes appear first?

I keep looking at only the numbers
I'm wondering if it's okay to view these changes in daily life as a standard.
