A system for managing exercise of an animal such as a human being so that the motion of the animal is induced with an appropriate scale and rhythm in accordance with the physiological conditions of the animal is provided. According to the exercise management system (1) of the present invention, during the process where the user's walking motion is induced by an operation of a walking motion induction device (20), a walking ratio (k) and a physiological variable such as consumed energy are measured. Then, the walking ratio (k) in the state where the physiological variable attains an appropriate value in consideration of activation of physical functions or reduction of body load of the user is set as a recommended walking ratio (k.sub.0). This ensures that the recommended walking ratio (k.sub.0) is set as appropriate in consideration of activation of the physical functions of the user or the like. As the walking motion is induced based on this recommended walking ratio (k.sub.0) by the walking motion induction device (20), the induction scale and rhythm can be controlled appropriately so that the step width (q) and the walking rate (p) are appropriate in consideration of activation of the physical functions of the user or the like.
