High-low machine

A high-low machine comprising:

• a support frame (110) mounted on a floor;
• a main body frame (120) connected to the support frame (110) to form a support structure;
• a weight part (130) mounted to be able to rotate at one point on the main body frame (120) and on which a weight plate (131) is mounted;
• a rotating part (140) rotatably mounted at another point of the main body frame (120);
• a connecting part (150) provided to connect the weight part (130) and the rotating part (140) to transmit a load of the weight plate (131) to the rotating part (140) and to enable length adjustment between the weight part (130) and the rotating part (140);
• and
• a grip part (160) connected to a free end of the rotating part (140) and providing a space for a user to grip;
• and
• wherein the grip part includes:
• a pair of handles (161) provided for the user to grip;
• a pair of first angle adjusters (162) respectively provided at one end of each of the pair of handles (161) and configured to respectively adjust an angle of the pair of handles (161) with respect to a first axis;
• and
• a pair of second angle adjusters (163) respectively provided to connect another end of each of the pair of first angle adjusters (162) to the free end of the rotating part (140), and to respectively adjust the angle of the pair of handles (161) based on a second axis orthogonal to the first axis;
• and
• wherein when the grip part is lowered due to an external force applied by the user, the lowering of the grip part occurs in an arc motion path, and when the external force applied by the user is released, the grip part returns upward along the arc motion path via the load of the weight plate (131).
