A body movement detection device is provided with a main body, a display unit, and a control unit, the control unit including an ascent/descent method detection unit that detects whether a user who is wearing or carrying the main body is ascending/descending using a lift device, a counting unit that counts the number of times that the user ascends/descends using the lift device and the number of times that the user ascends/descends without using the lift device, based on the detection result of the ascent/descent method detection unit, and a display control unit that causes the display unit to display each of the values counted by the counting unit. The method by which the user ascends/descends can thereby be clearly displayed.
