Bend both knees into the chest, wrapping your arms around the shins and hugging them tightly.
Release your arms and let both knees fall to the left side.
Extend your arms into a T-position and turn your head to the opposite side of your bent knee. You can increase the stretch by crossing the right knee over the left thigh.
Hold here for at least 30 seconds, feeling your spine lengthen and twist. You may even hear some "cracks."
Use your abs to lift your knees back to centre and twist to the other side.
