Exercising machine

An exercising machine comprising a frame including a pair of forwardly and rearwardly spaced stands and rail means extending between said strands, a rearward one of said stands including first stub means, a sliding board of shorter length than said rail means and movable lengthwise therealong between forward and rearward positions, said sliding board being elongated in the front-to-rear direction and having front and rear ends with a second stub means mounted closely adjacent said front end, at least one elastic band wrapped around said first and second stub means for biasing said sliding board toward its rearward position, means for securing said front end of said rail means at vertically spaced locations on a forward one of said stands for adjusting the inclination of said rail means, a rope, a pair of handles attached to opposite ends of said rope, a system of pulleys mounted on said board and a front region of said rail means around which said rope extends such that a user positioned on said sliding board causes said sliding board to move forwardly against the bias of said at least one elastic band by pulling on said handles, said pulley system arranged to create a velocity ratio between said handles and sliding board to be 2:1 or greater.
