Three-point adjustment multi-purpose exercise machine

A three-point adjustment multipurpose exercise machine, comprising:

• a. a frame including a first substantially upright post;
• b. said first substantially upright post describing a substantially vertical axis;
• c. a slidable carriage assembly having means to slide and lock on the first substantially upright post along said substantially vertical axis;
• d. a right arm assembly and a left arm assembly, each rotatably, adjustably, and independently mounted to said slidable carriage assembly and each said arm assembly having an axis of rotation, the left arm assembly having a left handle unit and the right arm assembly having a right handle unit;
• e. a resistance assembly;
• f. at least one cable coupling the left handle unit and the right handle unit and the resistance assembly, wherein there is a tension in the at least one cable;
• and
• g. means for keeping the tension in the at least one cable substantially the same;
• wherein the slidable carriage assembly, the left arm assembly, the right arm assembly, the left handle unit, the right handle unit, the at least one cable, and the first substantially upright post are configured so that when and as a vertical height of the slidable carriage assembly along the first substantially upright post is adjusted, a height of the left handle unit and a height of the right handle unit adjusts;
• wherein the adjustment of the vertical height of the slidable carriage assembly describes a first point of adjustment for the machine for adjustment of the vertical height of the left handle unit and the right handle unit;
• wherein the right arm assembly is rotated with respect to the first substantially upright post in a manner that causes at least a portion of the at least one cable to move;
• and when and as the right arm assembly is rotated with respect to the first substantially upright post in a manner that causes at least a portion of the at least one cable to move,
• wherein the left handle unit moves with the left arm assembly and the right handle unit moves with the right arm assembly;
• wherein the right arm assembly is mounted to the slidable carriage assembly at a right arm mounting point, wherein the right arm mounting point describes a second point of adjustment for the machine for adjusting a horizontal span of the right handle unit;
• and
• wherein the left arm assembly is mounted to the slidable carriage assembly at a left arm mounting point, wherein the left arm mounting point describes a third point of adjustment for the machine for adjusting a horizontal span of the left handle unit;
• and
• wherein the adjustment of the vertical height and the horizontal span of the left handle unit and the right handle unit adjusts an exercise position for the machine.
