Place a cable pulley at the lowest position with a cuff attachment. Position the cuff just above the ankle on left foot and stand so that right leg is closest to the machine. Balance on the right leg (if necessary hold on to the machine for support) keeping the right knee slightly bent and the back straight; lift the left leg directly to the left (allowing the cable to pass in front of body.) Lift the leg to a comfortable height (caution: lifting too high could cause a hip impingement and pain) before slowly lowering the left leg to the initial starting position. Perform all repetitions on the left leg before switching legs.
