Standing facing one cable station with an ankle strap secured around one ankle and attached to the cable machine. Grip the cable pillar firmly, brace your core and maintain a flat back as you kick your leg back at a 45 degree angle to your body, squeezing your glutes as you do so and exhaling. Be sure not to extend your leg too high. Slowly return your leg to the starting position, inhaling as you do. Repeat all the required reps on one leg before changing to the other.
