Abstract
Abstract An exerciser having a base, a rigid supporting platform with forward and rear end portions, the forward end portion of the supporting platform pivotally mounted on the base. Antifriction means are secured to the underside of the base to prevent slipping. The rear end portion of the rigid exerciser platform is mounted on a pair of floor-engaging rollers fixed to roll about an arc around the pivot axis. A braking means is associated with the rollers to regulate the body force required to rotate the rollers and the amount of brake resistance is adjustably controlled. Upstanding spaced-apart foot-retaining guides are adjustably secured to the platform and foot stops are secured to the platform adjacent the rear ends of the retaining guides.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
137 words
An exercising device, comprising: a. a floor engaging base, b. a substantially flat and rigid exerciser platform having forward and rear end portions, c. pivot means interconnecting said base and the forward end of said platform is pivotal spaced-apart relationship so that said platform pivots in a generally horizontal plane relative to said base, d. floor-engaging roller means secured to the underside of the rear end portion of said platform and positioned so as to traverse an arcuate path around said pivot means, e. spaced-apart foot-retaining guides adjustably secured on said platforM generally on the rear end portion thereof for permitting the user to transfer lateral force of the feet to pivotal movement of said platform around said pivot means; and f. brake means on said roller means to increase lateral force required to pivot said platform.
