SWISS BALL SINGLE LEG WALL SQUAT – With a swiss ball pressed between your lower back and a wall, stand with your feet hip width apart and approximately 10cm in front of your body, keeping your knees soft. Engage your core and lift one foot off the floor bending at the knee and taking the leg behind you as if in a lunge. With your weight through your standing heel, bend that knee to approximately 90 degrees keeping it in line with the second and third toes, as you lower your body down the wall. Check your standing knee remains behind your toes. Drive up through the heel to return to the starting position. Easier version: keep the toe of your back leg on the floor.
