Place your hands on your hips and soften your knees.
Keeping your upper body still, gently thrust your hips forwards, tucking your tail bone in, and then backwards, pushing your tail bone out.
Thrust your hips to one side, pulling your hip upwards, and then to the other side.
Progress the exercise to combine all these movements and perform circles in each direction.
Gradually increase the size of the circles before you change and rotate in the other direction.
