A stepper includes a base, a connecting rod, two pedals, and two mechanisms. The connecting rod is placed on the base. Each of the adjusting mechanisms includes a blocking member, an adjusting base, and an eccentric member. The blocking member includes a first blocking surface. The adjusting base is placed on the base. The eccentric member is rotatably placed on the adjusting base and includes at least two second blocking surfaces. The two second blocking surfaces selectively resist the first blocking surface. Once one of the pedals is lowered, one of the first blocking surfaces and one of the second blocking surfaces are inclined for connection of one end portion of the connecting rod, the other end of the connecting rod is concentrically rotated, and the other first blocking surface is subjected to resistance by the other second blocking surface. Then, the other pedal is rotated and raised. |
