Abstract:
In a leg exercise machine having a support frame, 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, a resistance structure for providing resistance to the leg exercises performed on the machine, a first roller cushion assembly pivotably connected to the frame about a first pivot axis, coupled to the resistance structure and adapted to be engaged by an exerciser's legs, and a second roller cushion assembly pivotably secured to the frame about a second pivot axis and adapted to be engaged with an exerciser's thighs when performing leg curls, the improvement wherein:the seat bottom is selectively adjustable relative to the frame such that a distance between a planar top of the seat bottom and a parallel plane including the first pivot axis when performing leg extensions is less than the distance between the planar top of the seat bottom and the parallel plane including the first pivot axis when performing leg curls, and wherein the seat assembly includes a pair of spaced apart, seat base frames joined together at one end by a stop tube having a pair of stop pads projecting therefrom.
