Continuous Horsepower (“CHP”) is a term used in the treadmill industry for consumer comparison purposes. The CHP rating is measured in laboratory testing using a dynamometer, which measures the mechanical power of the motor. The CHP rating does not denote the operational horsepower of the treadmill in ordinary household use. In ordinary household use, the motor does not operate at the horsepower shown.
