  • Patent number: 4728102
    Abstract: A resistance or load indicator for use with an exercising unit, in particular one which has motions or movements in opposite directions for exercise, such as reciprocal arm or leg exercisers, and in particular one which can be used with coordinated movements of the arms and legs. The resistance indicator unit comprises an indicator plate that is frictionally loaded to turn from a centered position as the exercise load is applied. The indicator plate is spring loaded so it will turn until the friction control slips. The amount of movement of the spring loaded plate indicates the load being applied in either direction.
