The present application is provided a personalized exercise simulation system. The system includes a microprocessor, an equipment adjustment unit, a displayer, a reality controlling parameter transmitting port, a reality controlling parameter unit, a reality image unit, a path trajectory data memory, a displayer, a controlling instruction outputting port. The microprocessor acquires a path coordinate, path parameter from the reality controlling parameter unit and an equipment adjustment instruction produced by the equipment adjustment unit. Then the processor outputs the instruction to the exercise device by the outputting port to adjust one of speed, gradient, or resistance of the exercise device. Meanwhile, the microprocessor acquires a reality image corresponded to the path coordinate from the reality image unit, and then display the reality image on the displayer. The present application further includes one of a camera device, a position system, or one piece of map information.
