Abstract
Abstract An exercise device for muscle conditioning of an individual in an upright position, which includes a frame having a first and second rail, a first and second pedal stem connected to said first and second rail, respectively; a pedal connected to an end portion of each of the first and second pedal stems and upon which the feet of the individual are placed; and a mechanism mounted on the frame for pivotally connecting at least the first pedal stem to the first hand rail so as to allow for movement of the at least first pedal stem toward and away from the second pedal stem for conditioning the muscles of the individual in the upright position.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
193 words
An exercise device for leg muscle conditioning of an individual in an upright position, comprising: a rectangular, box-shaped frame having at an upper portion thereof a first and second parallel and horizontally oriented hand rail and a third and fourth parallel and horizontally oriented hand rail interconnecting said first and second hand rails, respectively; a first and second pedal stem mounted on said frame; a pedal connected to an end portion of each of said first and second pedal stems and upon which the feet of the individual are placed; and means mounted on said frame for pivotally connecting said first pedal stem to said first hand rail so as to allow for movement of said first pedal stem towards and away from said second pedal stem in a single plane of motion perpendicular to said first and second hand rails along a longitudinal axis of said frame for conditioning of the leg muscles of the individual in said upright position and to allow for support of an upper portion of said individual between said third and fourth hand rail upon movement of said first pedal stem in said single plane of motion.
Claim 2
Dependent Claim
193 words
An exercise device for leg muscle conditioning of an individual in an upright position, comprising: a rectangular, box-shaped frame having at an upper portion thereof a first and second parallel and horizontally oriented hand rail and a third and fourth parallel and horizontally oriented hand rail interconnecting said first and second hand rails, respectively; a first and second pedal stem mounted on said frame; a pedal connected to an end portion of each of said first and second pedal stems and upon which the feet of the individual are placed; and means mounted on said frame for pivotally connecting said first pedal stem to said first hand rail so as to allow for movement of said first pedal stem towards and away from said second pedal stem in a single plane of motion perpendicular to said first and second hand rails along a longitudinal axis of said frame for conditioning of the leg muscles of the individual in said upright position and to allow for support of an upper portion of said individual between said third and fourth hand rail upon movement of said first pedal stem in said single plane of motion.
