A device for stretching or flexing the calf muscles and tendons of the lower leg, the device in one embodiment having a base member formed with a 90 degree angle for positioning at the intersection of two walls and a floor, the base member having elevated non-skid planar surfaces emanating from the 90 degree angle to the edge of the base plate allowing a user to stand on the elevated non-skid surfaces with both feet and use one's body weight to stretch the calf muscles by lowering or raising ones heels below or above the plane of the elevated non-skid surface. In another embodiment, the device consists of a base member having a straight wall engaging edge with an upstanding wall, terminating in a flat planar surface and an angled ramp surface communicating between the flat upper surface and the base member, the calf stretcher allowing the user to stand on the base member and place selective right or left foot onto the ramp section for the respective stretching of the calf. Either embodiment may be used cooperatively with a wall or as a stand alone apparatus and may incorporate a stable hand rail.
