How does exercise increase muscle size?

How does exercise affect muscle size?

Resistance exercise affects muscles by increasing the formation of myofibrils, thereby increasing the thickness of muscle fibers. This added structure causes hypertrophy, or the enlargement of muscles, exemplified by the large skeletal muscles seen in body builders and other athletes (Figure 2).

How much does exercise increase muscle growth?
