CABLE GLUTE KICKBACK
Begin by standing in front of the cable machine with one leg on the floor and the other attached to the cable machine by an ankle cuff. Keep a soft bend in both of your knees and extend one of your legs outwards, fully contract your glute muscles at the end of the motion. Return your leg back to the starting position and repeat.
At full extension, squeeze your glutes for a second in order to achieve a peak contraction. Then slowly bring your working leg forward, resisting the pull of the cable until you reach the starting position. Repeat for the recommended amount of repetitions then switch legs.
