An exercising apparatus includes a frame body having a lower beam and an upper beam fixed together by a post. A seat is provided on a rear end of the upper beam. Three roller sets are fixed in the frame body. A wheel is rotatably supported by the roller sets and is inscribed in the roller sets. The roller sets are evenly distributed around a peripheral surface of the wheel. Two pedals are fixed on both sides of the wheel and are 180 degrees apart. The wheel is rotatably engaged with the roller sets in frictional relationship.
