A pedal adjustable system for an exerciser includes a casing composed of an end member and two side plates connected on two ends of the end member. An adjusting unit is received in the casing and has a threaded rod which can be rotated to move the adjusting unit. The tubular body has two side portions which are movably engaged with two slots in the two side plates. Two pivotal plates each have an end connected to the side portion corresponding thereto and the other end of each of the two pivotal plates is pivotably connected to a pivotable unit on which a pedal is connected. The inclination of the pedal can be adjusted by the user to rotate the threaded rod to pivot the pivotal plates together with the pedal.
