Abstract
Abstract The conventional exercise device for performing sit-ups includes a base and a strap for holding the feet of the user on the base. The number of consecutive sit-ups performed by an exerciser can be dramatically increased by using an exercise device including a frame, and footrests, calf supports, thigh supports and a seat on the frame, with each of such elements being adjustable in terms of position and inclination on the frame.
