Abstract: An exercising device is designed to exercise the oblique and waist muscles of a user as well as the upper torso and mid section of the abdominal area. The exercising device creates resistance by using elastic straps attached to a special curved shoulder bar, and the straps are anchored to a combined seat and seat bar which is held steady by the exerciser's own body weight. A resistance band positionable between the exerciser's legs which is affixed to the seat allows him to apply opposite force to ensure a proper form of exercise.
