Share on Facebook an exercise machine in which the lifter pulls on a handle attached to a cable. The main difference between an exercise in which the resistance is transmitted through a cable rather than being done with free weights is that the force is in the direction of the cable rather than always pointing downwards. For example, when using a cable machine to perform curls , the cable may continue to provide resistance at the top of the movement while the resistance the biceps must work against when lifting free weights is minimal when the forearm is at or near vertical.
