An apparatus for abdominal exercise comprises a pair of laterally spaced u-shaped support rails for rocking back and forth on a surface. A pair of arm rests are each connected to the inside u-shape portion of one of the support rails and extend rearwardly from the contact point to the surface to receive an elbow of a person disposed between said rails in a supine position. A first connecting portion connects the support rails above the contact point to the surface. A second connecting portion connects the support rails behind the contact point to the surface. A plunger is connected to said first connecting portion whereby a person disposed supinely on said support surface and between said support rails and with one of the hands or arms of the person engaging said first connecting portion is able to conduct a curling exercise to exercise the abdominal muscles of the person while rocking said device, and wherein said plunger is positioned to engage a user's abdomen to provide a kinetic and isometric force.
