According to the second aspect of the present invention, the handle includes a U-shaped handle main body that is rotatably supported by the distal end portion of the movable arm, and extends outward from the open ends of both side portions of the handle main body. The left and right grips are provided, and the handle main body rotates to form an inverted U shape. Therefore, there is no possibility that the bottom of the handle main body will hit the trainee's head, and the head can be made almost upright to perform high pulley motion.

  Further, as another aspect of the handle, as in the invention described in claim 3, when the handle body is inverted, the handle body can be trained by grasping the bottom of the handle body. In this case, when the handle body is reversed, the suspension movement can be performed, and the upper arm bilateral muscles and the like are trained.

  According to a fourth aspect of the present invention, on the basic frame, a seating portion on which a trainee sits is disposed so as to be movable up and down in conjunction with the movable arm, and the seating portion rises when the handle is pulled down. It is characterized by that.

  Therefore, when the handle is pulled down, the seating portion and the handle approach each other in the vertical direction, and it is possible to effectively train while reducing an unreasonable burden on the muscle.

  According to the inventions of claims 1 to 4, since the trainee can perform a high pulley motion with the head substantially upright, there is no need to pull down the back of the neck with the head protruding forward as in the prior art. The latissimus dorsi and the great circular muscles are effectively trained while reducing the strain on the neck and shoulder muscles.

  In particular, according to the invention described in claim 3, since the suspension motion is possible when the handle is reversed, the trainee can appropriately select the high pulley motion and the suspension motion and perform the necessary muscle training.

  Moreover, according to the invention of claim 4, it is possible to effectively train by reducing an unreasonable burden on muscles and improve exercise efficiency.

  Therefore, the trainee can perform a high pulley motion with the head almost upright without paying attention to the bottom 49 of the handle body 46. As a result, it is not necessary to pull down the back of the neck with the head protruding forward as in the prior art, and the latissimus dorsi and great circular muscles are effectively trained while reducing the burden on the neck and shoulder muscles.

  Further, if the handle body 46 is inverted in the direction of the arrow U and switched from the left and right grips 48 to the grip 51 for suspension, the suspension movement can be performed as shown in FIG.

  That is, the user grips the suspension grip 51 as shown by an arrow W in FIG. 13 while resisting the load of the weight block 24 while sitting on the seat pad 35 and with both knees applied to the knee pad 36. Thus, by alternately repeating the operation of pulling down the handle body 46 and the operation of returning the handle body 46, the upper arm biceps, etc. are trained.

  Therefore, the trainee can train the necessary muscles by appropriately selecting the high pulley motion and the suspension motion by rotating the handle body 46 and switching the grip. In this sense, a multi-function machine capable of training a plurality of muscles with a single machine is provided, and the efficiency of training is improved.

In this case, when the handle body 46 is pulled down, the distal end portion of the movable arm 18 rotates in the direction of the arrow G. Therefore, as shown by the arrow R in FIG. The position rises. Accordingly, the grips 46.51, the seat pad 35, and the knee pad 36 approach each other in the vertical direction, and it is possible to effectively train while reducing an unreasonable burden on the muscles, thereby improving exercise efficiency.
