Abstract
A leg exercise machine has a support frame and a seat assembly including a seat bottom disposed upon a mounting framework secured on the frame for performing leg exercises in the form of leg extensions and leg curls. The resistance structure provides resistance to the leg exercises performed on the machine. A first roller cushion assembly is pivotally connected to the frame about a first pivot axis, is coupled to the resistance structure and is adapted to be engaged by an exerciser's legs. A second roller cushion assembly is pivotally secured to the frame about a second pivot axis and is adapted to be engaged by an exerciser's thighs for performing leg curls. The invention is improved such that at least a portion of the seat assembly is selectively adjustable relative to the frame such that the vertical distance between the first pivot axis and the plane of the seat bottom when performing leg extensions is less than the vertical distance between the first pivot axis and the plane of the seat bottom when performing leg curls.
