When muscles grow in size we call this hypertrophy.

The word hypertrophy actually refers to an increase in the size of an organ due to an increase in the size of the cells, rather than to an increase in the number of cells. Other body tissues can actually undergo hypertrophy, such as the heart or kidneys (this is usually a bad thing). To differentiate, we usually refer to muscle growth as muscle hypertrophy, but the term is so often applied to muscle building that this is usually not necessary in lay discussions.

Increases in size due to an increase in the number of cells (cell proliferation, by the way, is called hyperplasia.
