<p>A resistance system for an exercise device includes a frame, a resistance element such as elastic bands, coil springs, weight plates, pneumatic or hydraulic cylinders. An interference element such as a plate, chain or one or more links is supported by a support plate mounted on the frame. Selective engagement with the resistance element is provided by actuation of a dial, other actuator or controller or directly by the user. Thereby the resistance element can be selectively engaged or disengaged to vary the resistance to the user.</p> |
