Abstract
An apparatus for performing exercises has a support frame and a seat mounted on the support frame. An exercise arm is pivoted adjacent the forward end of the seat for swinging back and forth in front of the apparatus. A load bearing cable is linked at the forward end of the arm. A leg engaging device is adjustably or rigidly attached to the arm for engagement by an exerciser's legs while performing different exercises. A handle can be releasably attached to the cable or to the exercise arm for performing upper body exercises.
