When do muscles start to grow?

In the first phase, your system focuses on learning new kinds of movements, so your muscles don't grow but keep on stretching. This nervous system learning process means that your muscles will be able to make more effort. This phase lasts for 6-8 weeks, and afterwards muscles start to grow visually, providing that they get the necessary amount of protein. It can take much more time until the increase of muscles begin, the reason being that your body forces your nervous system to conform to the learning process, instead of muscle-building.

The basic reason for the growth of muscle size and muscle power is regular overloading. If the muscles get suitable overloading, their power and size grows, and their tone improves.
