Abstract: A rower exerciser includes a frame which is disposed on the floor to serve as a supporting frame, a slide rail connected between front end rear ends of the frame, and a slide seat slidably mounted on the rail to slidably reciprocate along the rail and being adapted for sitting by the user. Two sides of a front end of the slide rail are respectively connected to outwardly extending curved arm frames. Each of the arm frames is connected pivotally to a rocker via a universal connector. The rocker and a respective one of the arm frames are connected pivotally to a hydraulic rod via a pivot seat. By adjusting the foot pedals and the slide seat to be in a fixed mode or a slidable mode, and by virtue of the universal connector and the pivot seat, the rockers can rotatably swing to enable the user to simulate actual rowing actions and to provide various exercising effects.
