The present invention is an exercise machine to be used mainly for lower body exercises that involve quads, shins, thighs, and hip areas of a user and provides a moving seat frame that supports the weight of the user to use it as a source of a resistance as a pedal is pushed away. The resistance can be adjusted by changing the ratio between the seat movement and the pedal movement. The machine can be foldable for a stowed position. A preferred embodiment includes a base assembly that stands on a floor, a seat assembly movable substantially in vertical direction to support the user's weight and use it as a source of the resistance, and a pedal assembly supporting a pedal that moves away from the seat assembly when pushed by the user. The pedal assembly and the seat assembly are linked together so that when the pedal is pushed away, the seat assembly is lifted up from its rest position. The amount of the lift on the seat assembly per given displacement of the pedal can be adjusted by changing the leverage between the pedal assembly and the seat assembly. Greater the lift on the seat assembly per given pedal displacement, greater the resistance the user feels on the pedal.
