A variable resistance abdominal bench is presented which has adjustable feet and handles. The adjustable feet and handles allow the bench to be adjusted to the size of the particular user of the equipment. The bench also has a torso part and a seat part. The torso and seat parts are pivotable. Attached to the torso part of the bench is a weight that slides along a track underneath the torso part. The weight can be placed on either side of the pivot point so that a negative or positive resistance can be created. The exerciser thus has the option of doing an assisted sit-up or doing a sit-up against an added weight.
