Abstract
A cable exercise machine includes a first pull cable and a second pull cable incorporated into a frame. Each of the first pull cable and the second pull cable are linked to at least one resistance mechanism. The at least one resistance mechanism includes a flywheel and a magnetic unit arranged to resist movement of the flywheel.
Claims20
A cable exercise machine comprising:
- a frame;
- a first pull cable, a second pull cable, a third pull cable, and a fourth pull cable incorporated into the frame;
- a resistance mechanism linked to the first pull cable, the second pull cable, the third pull cable, and the fourth pull cable, the resistance mechanism comprising:
- a central shaft;
- a flywheel connected to the central shaft;
- revolution magnets configured to rotate with the flywheel;
- and
- resistance magnets arranged to selectively resist rotation of the flywheel;
- a magnetic sensor configured to count the revolution magnets as they rotate to track a number of partial revolutions of the flywheel;
- and
- a control panel configured to receive as input a level of magnetic resistance exerted on the flywheel by the resistance magnets and the number of partial revolutions of the flywheel to calculate an amount of work performed during a workout by pulling on any of the first pull cable, the second pull cable, the third pull cable, and the fourth pull cable, the control panel including an output device configured to present the calculated amount of work performed during the workout.
