ABSTRACT:
A digital resistance indicator for P.S.I. Nordic Track, of Chaska, Minn., under the mark NORDIC TRACK exercise machines is provided for use with exercise machines having a frictional resistance device for creating a resistive force in response to reciprocating arm movements by an operator. The resistance indicator comprises a resistance adjustment device, operatively connected to the frictional resistance device, for varying the level of the resistive force; and a digital indicator, coupled to the resistance adjustment device, for displaying a numerical value corresponding to a particular position of the resistance adjustment device. The resistance adjustment device may comprise a rotatable handwheel, a lever, or any other suitable element which can be grasped by the human hand and used to impart an increase or decrease in resistive force to the frictional resistance device. Preferably, the digital indicator can be adjusted independently of the position of the resistance adjustment device so that any desired numerical value can be made to correspond to a particular resistance setting. A stabilizer bracket is connected between the digital indicator and any fixed portion of the exercise machine for preventing movement of the digital indicator relative to the exercise machine while in use. If desired, the digital indicator may be coupled to the resistance adjustment device by a flexible shaft so that the digital indicator can be conveniently positioned for greater visibility to the operator.
