Muscles shrinking when not used is the body being economic.
Muscles are made up of cells, and cells are living things. Living things need energy - food, one way or another, only to remain alive.
So even if you aren't using them at the moment, it's costing the body an effort only to keep them around.
And the body is economic. It doesn't like to spend effort on something that isn't being used.
If you're not using a muscle(much), the body will eventually stop maintaining those muscle cells it doesn't need. And the muscle as a whole will begin to shrink. It'll shrink to the point where what remains is what it needs to be able to do what you normally ask it to do.
