Abstract: An abdominal exercise assembly for exercising abdominal muscles includes a plate that is rigid. The plate has a first end that is configured to insert between a mattress and a box spring of a bed. A second end of the plate is positioned proximate to an edge of the bed. A support is slidably coupled to the second end. The support is configured to position proximate to and parallel to the edge of the bed. A bar, coupled to the support distal from the plate, extends bidirectionally from the support in parallel with the second end of the plate. The bar is configured to be selectively vertically positioned relative to the plate. The plate is retained in a substantially horizontal configuration by a combination of the weight of the mattress and a user positioned on the mattress. The bar is configured to selectively position legs of a user.
