Target: The spine, back, obliques, pelvic floor and core

How to

1.  Sit up tall with the feet wide and the legs straight. Place the ring between the legs with the hands on top of it. Ensure you are sitting tall and the arms are straight

2. Exhale to release one arm and twist to one side. Inhale to return to centre. Keep the hips still and the arms strong throughout the movement

Tip: If you are finding it hard to sit up tall, you can do this one sitting on a chair or elevated on a bolster

Reps: 6 to 8 each side
