Abstract
A computer-controlled exercise sit up machine has a frame supporting a bed on which a user may rest his or her body, knee support posts for resting the user's knees, and foot rest support posts for receiving the user's feet and ankles. The exercise sit up machine has a triangular-shaped housing which acts as a fulcrum for pivoting the frame about a transverse axis so that the bed is inclined to a position where the user performs sit ups with the head at a higher vertical level than the feet. A computer controls a motor housed in the triangular-shaped housing for pivoting the frame about the fulcrum. The user may select a desired sit up routine. The computer then operates the machine through the chosen sit up routine and calculates and displays a sit up coefficient score to apprise the user of his or her performance.
