ABSTRACT:
A recumbent stepper includes a frame, a pair of lever arms, pedals, pulleys, flexible members, springs and adjustable resistance devices The pair of lever arms are pivotally attached to the frame and are movable from a retracted position to an extended position. Pedals are attached to each lever arm. The pair of pulleys are rotatably attached to the frame. The pair of flexible members are attached between the lever arms and pulleys and are wound around the pulley when the lever arm is in the retracted position and deploys as the lever arm moves to the extended position. Springs are operably attached to each pulley such that each lever arm is biased to the retracted position. Adjustable resistance devices are operably connected to each pulleys whereby increasing the resistance on the pulley increases the force required to move the lever from the retracted position toward the extended position.
