An isokinetic resistance exerciser in the form of a treadmill is the subject of the present invention. An improved isokinetic resistance is provided by oversized frictional members and flat centrifugal plates which respond to centrifugal forces to cause inter-engagement of the frictional surfaces. The invention also includes a centrifugally-responsive speed register mechanism and a device for recording the total work expended by a person exercising. The centrifugally-responsive actuating mechanism employing flat plates in place of conventional weights results in improved operating characteristics.

Exercise apparatus comprising: a rotatable shaft; a first member presenting a first surface; means for holding said first member against rotation with the shaft; a second member presenting a second surface and being coupled with the shaft for rotation therewith and movable toward and away from said first surface for engagement with the latter upon rotation of the shaft; means adapted to be acted upon by a user of the apparatus for rotating said shaft; a plurality of generally flat plates extending longitudinally in a direction parallel to said shaft and coupled with the latter; and plate mounting means comprising first disc means journaled on said shaft, collar means mounted on said disc means and extending therefrom in the direction of said plates, the ends of said plates abutting said first disc means, and second disc means being rigid with said shaft and spaced from said first disc means, said second disc means having slots for receiving the ends of said plates and presenting a keeper ring to restrain lateral movement of said plates while accommodating pivotal movement in a direction perpendicular to the restrained lateral movement, whereby said plates pivot in response to rotation of said shaft and in proportion to the speed of rotation thereby urging said second surface toward said first surface to increase the frictional resistance between the surfaces as the speed of rotation of said shaft increases and withdrawing the plates as the speed of rotation of said shaft decreases.
