ABSTRACT:
An exercise device comprises a base, two pedaling sets, and two damping apparatus. The base is formed of a front cross rod, a rear cross rod, a connection rod connecting the front cross rod and the rear cross rod, and a rotatable shaft fastened pivotally at one end thereof with the center of the front cross rod. The two pedaling sets are formed of two curved support rods and two pedals mounted on the support rods, and are fastened pivotally with two sides of the rotatable shaft. The pedaling sets turn along with the rotatable shaft. The base is provided with two arcuate protrusions located at two sides of the connection point of the front cross rod and the connection rod. The two support rods of the pedaling sets are respectively provided with a guide pillar. When the two pedaling sets are moved up and down, the arcuate protrusions are pressed against by the two guide pillars of the two support rods of the pedaling sets, thereby causing the two pedaling sets to turn sideways.
