Abstract: The present disclosure proposes an electric treadmill. The electric treadmill includes a base and an armrest. The base includes a front frame, a rear frame and a connecting assembly, wherein tread boards are provided within the front frame and the rear frame, and the front frame and the rear frame are hinged by the connecting assembly to enable the base to be folded. The armrest includes a vertical tube and a cross tube, wherein one end of the vertical tube is connected to the cross tube and the other end of the vertical tube is rotatably coupled to the base to allow the armrest to be foldable with respect to the base. The front frame and the rear frame may be folded with respect to each other, thus, a length of the base is greatly reduced for storage.
