An apparatus for massaging calves is able to adjust a distance between two plates, the apparatus having at least two plates that are arranged at a distance from one another and that come into contact with the calf during massage on both sides thereof, and having a drive shaft, the plates being connected to the drive shaft by coupling members in such a manner that a rotational movement of the drive shaft brings about a movement of the plates for carrying out the calf massage. A distance adjusting mechanism is also provided in order to adapt the distance between the two plates to the size of the calf to be massaged.
