How do muscles grow if only the volume increases and not the number of muscle fibers? What do you make at and where/at what level of the muscle?

Answer
The muscle cells make more contractile proteins (actin, myosin, etc.). That happens at the cellular level. If the muscles are not used, some of these proteins are broken down again. The image below is about the heart muscle, but the principle is the same.
