Abstract: An apparatus for supporting a weight on a supine person's abdomen for performing abdominal exercises, including a base and a platform removably resting on the base. The platform has at least one depression for receiving a curl barbell, a straight barbell, and/or dumbbells. Optionally, pegs may extend from the platform surface for maintaining the position of a stack of disc weights laid on top of the platform. Optionally, the platform under surface has resilient palm pads for the user to aid in stabilizing the apparatus while in use. The base has a curved underside with padding and rests on the user's abdomen. A unitary embodiment is a rigid plate. A two-part embodiment has a foundation with a tray and a pedestal that sits in the tray. Optionally, the curved wings extend from sides of the base down around the sides of the user's abdomen. Pins in holes position the platform on top of the base. Optionally, a removable latch secures the platform to the base.
