The invention discloses a bodybuilding bicycle based on a real map and a bodybuilding method. The bodybuilding bicycle comprises a displayer, a host, a control assembly and a playing control unit, wherein the displayer is used for displaying the real map, and the host is used for storing data of the real map, controlling the displayer to play the real map, extracting geographic data of corresponding positions in the real map and transmitting the geographic data to the control assembly; and the control assembly is used for adjusting one or more items of the direction, riding resistance and slopes of the bodybuilding bicycle according to the received geographic data, and the playing control unit outputs signals to the host to enable the host to control live-action movement in the real map. The bodybuilding bicycle and the real map are combined, the direction, riding resistance and slopes of the bodybuilding bicycle can be adjusted according to the geographic data of the corresponding positions in the real map, and thus riding states of a bodybuilder under real road conditions are simulated on the bodybuilding bicycle; and the bodybuilder experiences the outdoor bodybuilding effect in a room, and the exercising effect of the bodybuilder is improved.
