A body hauling mechanism includes a weight seat, a weight control assembly and a body hauling auxiliary part. The weight control assembly of the body hauling mechanism has an enclosure with a stretching mechanism configured inside. Said stretching mechanism is made up of a separating board, a gear unit, a cord rolling wheel, a back-stop mechanism and a driving wheel. The user can pull the two-way pulling cord to drive the stretching mechanism to control the weight control assembly hanged on the weight seat, so that the hauling cord of the weight control assembly can be retracted or released mildly, and can apply or release the hauling force smoothly. When using the body hauling mechanism to improve the symptoms caused by irritation or compression of the body nerves, secondary injury of the affected part can be avoided.
