An exercise device that effectively targets and engages the abdominal and core muscles. The device includes a backrest, a first graspable pole, a second graspable pole, a height-adjustable headrest, and a rocking base. The rocking base acts as the supporting structure and includes a first rocker, a second rocker, and a bridge. The first rocker and the second rocker are connected to the bridge on either side. The backrest receives a user's back and is adjacently and pivotably mounted to the bridge, opposite the first rocker and the second rocker. The first graspable pole and the second graspable pole are positioned opposite to each other across the backrest. The first graspable pole and the second graspable pole are each laterally and rotatably mounted to the backrest. The height-adjustable headrest is centrally mounted in between the first graspable pole and the second graspable pole to receive the user's head.
