Stand in front of a cable station with a stirrup handle attached to the low pulley. Adopt a split squat stance with one foot 2 ½ to 3 feet in front of the other ad only the ball of your back foot I contact with the ground. Holding the cable in the same hand as your back leg, begin by ending both knees ad descending straight down. In the bottom position both knees should be bent approximately 90 degrees ad your back knee should almost touch the floor. Pause for a second and then press back up to the starting position.
