Abstract
The present invention relates to exercise apparatuses having a resistance assembly which utilizes a compression spring in combination with a differential resistance arm to regulate the amount of resistance provided to the user for use in exercise. The resistance assembly of the present invention utilizes a compression spring, gas shock, or other known resistance mechanisms. The differential resistance arm is provided in connection with the compression spring to regulate the amount of resistance provided for use during exercise. The differential resistance arm includes a differential contact surface which has a substantially curved configuration. The curved configuration maintains a linear increase/decrease in resistance subsequent to input from a user increasing or decreasing the resistance.
