Abstract: A motor-less exercise treadmill including a main frame comprising a pair of spaced side-rail members having a bracket mounted transversely at a front end thereof, a U-shaped tubular rail mounted on the bracket having a grasp-rail and a pair of height adjustable front legs so as to permit the raising or lowering of the front end of the main frame, a generally rectangular platform support frame mounted substantially along the length and intermediate the side-rail members, a generally planar slider bed mounted on the platform support frame intermediate the side-rail members, a front and rear roller journaled transversely generally at the front and rear ends of the side-rail members, a pair of static rear legs substantially horizontally suspending the main frame from the floor surface, a first flywheel rigidly connected to the front roller and adapted to form a first pulley having a first end of an endless belt entrained thereabout, a second end of the belt entrained about a smaller diameter second pulley mounted

Abstract: An adjustable, recoiling aerobic exercise bench (20) which reduces the generation and transmission of impaction forces on a user's joints while performing conventional and power step exercises including a resilient platform (22) slidingly disposed in a left and right housings (36 and 38) which function to support the platform (22) above and relative to an exercise floor surface (42); a lateral platform recoiling assemblies is disposed between the platform ends (24 and 26) and inside lateral walls of the housings (36, 38) and adapted to generate lateral, resistive, restoring forces when platform (22) is moved downward during operation of the device (20); vertical platform recoiling assemblies (62), which includes a plurality of rigid tubular spring retainers, telescoping springs (90) mounted the undersurface of the platform and of sufficient length so as to make contact with the exercise floor surface (42) to thereby generate a vertical platform resistive restoring force when platform (22) is downwardly compre
