An exercising apparatus having a frame located forwardly of a supporting surface on which a person may assume a seated position with knees in a first position elevated above the supporting surface and feet in a second position lower than the first position. A leg stabilizer is supported by the frame to maintain the knees in the first position, and a pair of crank handles are supported by the frame for rotation about a common crank axis located near the first position. The pair of crank handles are located on opposite sides of the knees of the person to be movable by hands of the person through complete revolutions. The leg stabilizer may include a knee stabilizer in the first position and a foot stabilizer in the second position to ensure that the person's legs are bent at the knees though an angle approximating 90.degree..
