When you do excessive work, your muscles can become strained beyond their limits. This causes very tiny tears in the muscle tissues. (This is why you feel sore after a workout.) When your body is given time to heal, the torn tissue is mended with more muscle tissue. This is what causes an increase in muscle mass.
