An exercising apparatus includes a movable unit on which a user straddles and a driving unit for driving the movable unit. The driving unit changes a state of the movable unit to provide the user with an exercising load. A storage part stores corresponding relationships between the states of the movable unit and the messages, and a state detector detects the state of the movable unit at approximately the same timing as the output timing determined by an output timing determination part. A message output part outputs messages corresponding to the user's postures repeatedly during a period of providing the user with an exercising load. The message output part extracts the message corresponding to the state of the movable unit detected by the state detector from the storage part and outputs the extracted message at the output timing determined by the output timing determination part.
