A cycle exerciser has a one-way sprocket and a pair of one-way pinions disposed on a compound shaft. The one-way pinions are respectively rotated by a pair of lever arms (70) through a respective toothed element (50) and a connecting mechanism. The toothed element (50) engages and rotates a respective one-way pinion. The connecting mechanism comprises a substantially cylindrical swivel block and a torsional spring. The swivel block has a rim portion for fixedly securing to the toothed element (50) and a protruding swivel shaft for telescopically receiving one end portion of the lever arm (70). The connecting mechanism, which is fixed to the toothed element (50) by the rim portion thereof, connects to the lever arm (70) in such a way that the lever arm (70) can perform oscillatory and swivelling movement like rowing boats. The compound shaft is arranged to drive and energy absorbing wheel (80). <IMAGE>
