The present invention relates generally to exercise devices, and more specifically to exercise devices providing variable resistance when performing a wide variety of training movements. These exercise devices comprise a pulley system of elastic resistance bands or cords secured to a hinged A-shaped frame wherein the resistance imparted by the elastic bands or cords can be easily varied by engaging or disengaging individual resistance bands or lengthening or shortening individual bands.
