Abstract
Abstract An exercise device for the feet and legs, where the device has foot plates for exercising a supine person's feet; calf squeezers for compressing the calf muscles when the feet are exercised; and a support structure holding the foot plates in a vertical position and the calf squeezers in a horizontal position. Persons in a supine position exert a rocking movement of the foot plates and this rocking movement makes the calf muscles squeeze against the calf squeezer. This squeezing pumps blood out of the deep veins of the calf and prevents stasis of blood and clot formation in the deep veins of the calf.
