A pedal exerciser includes essentially a baseboard, two pedals each having one end connected to the baseboard and the other end supported by two air pumps, a V-shaped linking rod having a bottom portion fastened to a fixture and the other ends detachably secured to the pedals, respectively. A valve is adapted to adjust an upward force towards the pedals, thus the user may adjust the pedals to a desirable exercise resistance.
