According to the structural diagram of the running machine shown in fig. 1, the running machine is divided into a running device 1 and a lifting device 2, the lifting device 2 comprises a left lifting belt pulley 21, a right lifting belt pulley 22 and a lifting belt 23, the lifting belt 23 is wound around the left lifting belt pulley 21 and the right lifting belt pulley 22, and the left lifting belt pulley 21 and the right lifting belt pulley 22 are in a tensioning state. The upper half of the lifting belt 23 is approximately perpendicular to the horizontal plane. The lifting device 2 is mounted on the underframe of the lower part of the running device 1. During exercise, the lifting belt 23 and the running belt 13 rotate synchronously, and the lifting belt 23 lifts the running belt 13 in a state of being approximately horizontal to the horizontal plane due to the tension and the pulling of the upper parts of the left lifting belt pulley 21 and the right lifting belt pulley 22. The whole running machine belongs to an unpowered running machine, does not need to consume energy, and belongs to an environment-friendly product.
