Gluteus Kickback

Place your hands and knees on the floor, your knees should be bent 90 degrees so that your thighs are perpendicular to the floor. Head lifted up, raise the right leg up, and maintain 90 degree bend on your knee, until your thigh is in line horizontally with your torso or your foot is higher than your head. Squeeze your right gluts while slowly lowering your leg to the starting point. Do the same exercise with the left leg and repeat.
One additional thing you can add to this is incorporate a resistance band.
