A stepper exercise device includes a base support frame, a wheel assembly having a first wheel, a stepper assembly coupled to the base support base and first wheel of the wheel assembly, and a resistance adjustment mechanism coupled to the wheel assembly. The stepper assembly includes a first step pedal and a second step pedal coupled to a first side and a second side of the first wheel respectively. The first step pedal and the second step pedal are configured to move in an elliptical motion resembling a step motion of a user as if the user walked on the support surface. The resistance adjustment mechanism is configured to provide different amounts of resistance to rotational motions of the first wheel, which in turn provides various resistance to step motions of the first and second step pedals to adjust the intensity of the exercise.
