A multi-purpose abdominal and core exercising machine is an apparatus that allows a user to exercise their abdominal muscles through a variety of guided movements. The apparatus includes an incline-adjustable frame, a track, a swiveling seat, a height-adjustable headrest, a first graspable pole, a second graspable pole, and a backrest. The track is mounted onto the incline-adjustable frame. The backrest and the swiveling seat supports the user's body as the backrest slides along the track and the swiveling seat is terminally fixed to the track. The height-adjustable headrest is mounted between the two grasping poles. The proximal end for each grasping pole is rotatably connected to the backrest, which allows the user to hold the distal end for each grasping pole. Pulling the grasping poles towards the user's abdomen allows for a movement by the apparatus to exercise the user's abdominal muscles.
