Patent abstract
An exercise apparatus includes a cable that is pulled from a sheave when the extraction force is sufficient to rotate a drum that is linked to the sheave. A brake material is sandwiched between the drum and at least one tension band to provide adjustable resistance to rotation of the drum. A knob is rotated to adjust tension in the at least one tension band without adversely affecting tension in the brake material. Indicia associated with rotation of the knob show changes in the resistance level as the knob rotates through more than one complete revolution.
