An exerciser includes a base including a seat for supporting a user, a back frame rotatably secured on the base with a pivot axle for supporting the back of the user and for allowing the user to force and to rotate the back frame relative to the base about the pivot axle. A foot support is slidable relative to the base and selectively coupled to the back frame for allowing the back frame and the foot support to be moved in concert with each other. The back frame includes one or more brackets selectively secured to the base and the foot support with fasteners.
