A foldable step exerciser has a base and two pedal members symmetrically provided on two sides of the base. An interlock member is moveably connected to the base and a stopping element is mounted in a rear end of the interlock member and can slide along the base. A protrusion is mounted in a front end of the interlock member and two driving members are respectively mounted between each pedal and an end of the protrusion. When one of the pedals is treaded downwards, the other pedal is moved upwards via the protrusion being driven by the driving members and therefore, a user can exercise. When the interlock member as well as the stopping element is adjusted to move forwards and the pedals are not limited by the stopping element, the pedals can be folded for convenient storage.
