A compact portable leg exercise apparatus includes a top platform, a base member, a resilient member and a frame assembly interposed between the top platform and base member. The apparatus is sized to receive a foot onto the top platform to move the top platform relative to the base member and against a force provided by the resilient member as the apparatus is moved to the collapsed position. The apparatus is sized to fit in carryon luggage, handbag, backpack or be hand-carried, allowing for its use anywhere. The frame assembly aligns the top platform and base member and inhibits twisting motion of the top platform relative to the base member, thereby constraining the motion of travel for the apparatus. The frame assembly can include a plurality of hinged leaf pairs shaped to inhibit generation of noise by the frame assembly as it moves to the collapsed configuration during use of the exercise apparatus. The exercise apparatus is light weight, small, quiet and stable, allowing for it use at home, the office, in public, in the airplane, or even within a vehicle.
