Set the GR8Flex in the incline position so that the squat stand is flattened on the ground. Attach both handles on the cables and sit on the bench pad with your feet on the edge of the pad. Grab both handles and maintain stiff locked arms. In a situp position, extend your back until it touches the bench pad, and then get back to the starting position where your shoulders nearly touch your knees. Maintain an upright back position and locked elbows throughout the movement.
