摘要： An abdominal exercise device includes a frame comprising top, middle, and bottom frame sections. The middle frame section has a curved shape for creating a teeter-totter movement during exercise. The device includes a headrest connected to the bottom frame section, a plurality of connectors for connecting elastic bands to the frame, and an elastic band connected to at least two connectors. The two ends of the elastic band are connected to two straps. The device creates the teeter-totter movement to exercise the abdominal muscles in response to a person lying down in supine position with the back of the head on the headrest and the feet in the two straps, the person applying a downward pressure with the feet to the straps to move the headrest from a resting position, and the person removing the downward pressure to allow the headrest to go back to the resting position.
