Vertical pulldown machine

A vertical pulldown machine, comprising:

• a support frame seated on a floor surface;
• a body frame connected to the support frame to form a support structure;
• a pair of weight units rotatably mounted on the body frame and mounted with a weight plate;
• a pair of rotating units rotatably mounted on the body frame and provided to rotate respectively at a preset distance apart;
• a pair of connection units provided to connect the weight unit and the rotating unit to transfer a load of the weight plate to the rotating unit and to enable length adjustment;
• a pair of grip units connected to one end of each of the pair of rotating units and providing a space for a user to grip;
• and
• a sitting unit connected to the support frame and disposed in front of the body frame to provide a seat unit for the user to sit,
• wherein when a distance from one end close to the sitting unit of the support frame to another end close to the body frame is a width W, a center of the seat unit is located within a range of 34 to 43% of the width W from one end close to the sitting unit, and a rotation axis of the rotating unit is located within a range of 76 to 85% of the width W from one end close to the sitting unit;
• and
• when a distance from the floor surface to the top of the rotating unit is a height H, a center of the weight plate is located within a range of 13 to 22% of the height H from the floor surface, the rotation axis of the rotating unit is located within a range of 63 to 72% of the height H from the floor surface, and the grip unit is located within a range of 76 to 85% of the height H from the floor surface.
