Abstract: A device for aiding a person using the device in stretching his or her calves which comprises a pair of generally rectangular members which are hingedly connected along corresponding longitudinal edges to permit relative swinging movement of the members. The members may be swung from a collapsed storage configuration, having a distance up one surface of the A-frame configuration substantially equivalent to the length of the feet of the person using the device in which they overlie each other to a substantially A-frame configuration. A linkage mechanism in the form of a pair of pivotally connected arms extends between the undersides of the rectangular members to limit the amount that the members can swing apart. When the deivce rests on the floor in its A-frame configuration, the upper side of at least one of the rectangular members is inclined at a predetermined desired angle, for example forty-five degrees with respect to the floor.
