A body exerciser includes a base, a backrest member, a pair of handle members, an angled cantilever, a footrest unit and two elastic cords. The base has a seat member and two pairs of guide rings mounted to the top and bottom portions of the base. The backrest member is connected pivotably to the base adjacent to the seat member. A U-shaped connecting member is fixed to the backrest member. The handle members are connected pivotally to the U-shaped connecting member. The cantilever has a lower section which is connected pivotably to the base and an upper section which is connected to the footrest unit. The elastic cords extend through the guide rings on the base and interconnect the U-shaped connecting member and the footrest unit. The exerciser may be used to perform sit-ups, crunches, leg extensions, curls and pectoral fly exercises.
