Attach a cable to a low pulley and stand facing away from the machine. Place the cable around your ankle and stand with your feet shoulder-width apart. Keep your core engaged and your back straight throughout the exercise. Slowly extend your leg straight back, squeezing your glutes at the top of the movement. Pause for a moment, then return to the starting position. Repeat for the desired number of repetitions. Switch sides and repeat with the other leg.
