Claim:
1. A stepper comprising: a base; a linking rod disposed on the base, wherein the linking rod comprises two ends that are concentrically rotated with each other; two pedals, each of the pedals comprising: two adjusting mechanisms, each of the adjusting mechanisms comprising: a blocking member disposed in a corner of the pedal arm, the blocking member comprising a curved surface against the corner of the pedal arm and a first blocking surface; an adjusting base disposed on the base; an eccentric block pivotally connected to the adjusting base via an axial center on the adjusting base, wherein the eccentric block is rotatable around the axial center, the eccentric block comprising a plurality of second blocking surfaces, and one of the second blocking surfaces resists the first blocking surface; an adjusting member for adjusting a rotating angle or a position of the eccentric block; wherein when one of the pedals is lowered along a gravity direction, one of the first blocking surfaces and one of the second blocking surfaces are inclined relative to the gravity direction to correspondingly move one end of the linking rod, and the other end of the linking rod is concentrically rotated, and the first blocking surface of the other blocking member is resisted by one of the second blocking surfaces of the other eccentric block, thereby swinging and raising the other pedal.
