PROBLEM TO BE SOLVED: To provide a mat which old folks (roughly 50 years or older) living in apartments or condominiums use for indoor physical exercises without causing a nose problem to people downstairs, and a method of doing indoor physical exercises. SOLUTION: The indoor physical exercise mat is made up of an elastic body to prevent vibrational sounds of physical exercise from being transmitted to downstairs in which old folks move their lower limbs and forearms up and down in time to music to prevent their physical power from decreasing. The elastic body is composed of two layers and has protrusions on the surface of the upper layer and acts to appropriately stimulate the soles and is fitted into a lower layer so as to make the upper layer to be replaced in accordance with a user's sensation. The method of doing indoor physical exercises is for old folks and makes the old folks move their lower limbs and forearms up and down and back and forth in time to an enka, a Japanese popular song.
