<p>A resistance device (10) adapted for use in an exercising apparatus comprises a plurality of resistance elements (20), force transmission means (80) and a resistance adjusting means (70). Through the force transmission means (80), a user can apply an exercising force to the resistance elements (20) which in general provide a resisting force coming from atmospheric pressure. For adjusting the total resistance, the user may operate the resistance adjusting means (70) to determine which resistance element(s) is (are) enable to adjust the level of resisting force. <IMAGE></p> |
