An exercise apparatus and method for lower back, abdominal, and leg conditioning. The apparatus is configurable between a pivoting condition and a fixed position. In the pivoting condition, a backboard, pivotally mounted to a frame, is configured for a user to lay on the backboard and alternately raise and lower their hips, while supporting their feet on a foot plate. In a fixed condition, the backboard is positioned proximal to the foot plate, and a user may perform one or more abdominal exercises.
