Enjoy the physical benefits of walking while you sit. The Pedal Pusher is a unique step exerciser that helps improve circulation, reduce swelling and relieve pain. You control the height and speed of movement–as one pedal is pressed down, the other is elevated. Great to use while you read, work or watch TV... just sit back, relax and walk. Ideal for those with limited mobility. Knob in center of unit lets you adjust the tension to your abilities, ranging from no-strength-required to a more challenging workout. Plastic/metal stepper design is sturdy, lightweight and portable. 4 1/4"H x 12"W x 14 3/4"L.
