ABSTRACT OF THE DISCLOSURE This invention relates to a novel leg strengthening apparatus which is used for muscle development, exercise and rehabilitation. The apparatus comprises an air reservoir, a valve to control the flow of air into and out of the reservoir, a cylinder in communication with the valve and an actuator which is secured to a piston within the cylinder. The apparatus will produce isometric, concentric and eccentric contractions in a muscle and allows for differing velocities of exercise movement, which has not been possible to achieve with the prior art devices. The apparatus is simple in design and is adaptable for home use. It includes variable resistance and can provide maximum muscle strengthening ability in correlation to the strength curve of the preselected muscle. The apparatus achieves these objectives using no auxiliary fluid-supply source and is self-contained and safe to operate. All these features in a single apparatus are not found in the prior art devices.
