    Abstract: A foldable jogging machine comprises a handrail frame, and a machine stand which is formed of a front machine stand and a rear machine stand. The front and the rear machine stands are provided with a spindle. The spindles are driven by a motor via a track. The front and the rear machine stands are mounted pivotally on a swiveling shaft such that they can be folded. The front machine stand is connected with an elevating leg frame for bringing about a reverse moment of force relative to the swiveling shaft, so as to cancel out a forward moment of force which is brought about in relation to the swiveling shaft by the jogging machine and the weight of a user of the jogging machine.
