When a user needs to perform stretching training, the user holds the transverse handle 230 with both hands, pulls the first pull rope 240 to drive the eleventh movable pulley 260 to move upwards, and meanwhile, because the positions of the first pull handles 480 connected to the two free ends of the second pull rope 470 are unchanged, the parts of the second pull rope 470 located on the sixth pulley 440 and the twelfth pulley 490 are driven to ascend in the process that the eleventh movable pulley 260 moves upwards, so as to drive the eighth movable pulley 460 to move upwards, and further, the weight assembly is pulled to move forwards through the third pull rope 520; when the user gradually removes the pulling force applied to the first pulling rope 240, the weight assembly gradually resets to drive the eighth movable pulley 460 to move downwards, thereby driving the eleventh movable pulley 260 to move downwards and further driving the transverse handle 230 to move upwards for resetting, so that the user can cycle the next stretching action to achieve the purpose of stretching training. When a user needs chest-expanding training, the user respectively holds the first pull handle 480 with both hands to pull the second pull rope 470, and since the position of the transverse handle 230 connected to one end of the first pull rope 240 is not changed, the part of the second pull rope 470 on the right side is pulled, the eleventh movable pulley 260 does not move downward along with the first pull handle 480 in the process of pulling the first pull rope 240, and therefore, in the process of pulling the second pull rope 470 by the first pull handle 480, the second pull rope 470 drives the eighth movable pulley 460 to move upward, so that the weight component is pulled to move forward by the third pull rope 520; when the user gradually releases the pulling force applied to the first pull handle 480, the weight assembly is gradually restored, and the eighth movable pulley 460 is driven to move downward, so that the first pull handle 480 is driven to be restored, so that the user can cycle the next chest expansion action. Meanwhile, by the arrangement of the pulleys, on one hand, only one type of stretching training and chest expanding training can be performed at the same time, and unnecessary safety accidents caused by the fact that the training actions of two users conflict with each other due to the fact that the two users use one device to perform the stretching training and the chest expanding training respectively are avoided; on the other hand, the using amount of the pull rope can be reduced, the assembling difficulty can be reduced, and the cost can be reduced.

Further preferably, in order to avoid the possibility of the eighth movable pulley 460 and the eleventh movable pulley 260 swinging left and right during use, vertical first guide rails (not shown in the figure) are respectively arranged at positions corresponding to the eighth movable pulley 460 and the eleventh movable pulley 260 on the rear end surface of the pedal 110, and the mounting seats of the eighth movable pulley 460 and the eleventh movable pulley 260 are respectively slid on the first guide rails.
