A training device includes an information outputter, an exercise status detector, an arithmetic processor, and a stimulus signal generator. The information outputter includes at least one of an image output unit and an audio output unit. The exercise status detector includes a body portion, a first grip portion and a second grip portion provided on the body portion, and sensors that detect a motion of the body portion. The arithmetic processor issues training action instruction information through the information outputter, and evaluates a matching degree between the contents of the training action instruction information and the motion of the body portion, based on output signals from the sensors of the exercise status detector. The stimulus signal generator applies a stimulus signal to the arm of a trainee.
