Segmental thoracic extension over foam roll - hands behind head (Thoracic extension stretch, over roller, hands behind head, supine)

Place a foam roll across the floor.
Lie back with the foam roll running across the level of your spine that you would like to stretch.
Wrap your hands around the back of your head to support the weight.
Ensure you do not pull your head forward, keep it in line with the rest of your spine.
Inhale, then as you exhale allow your body to relax over the foam roll.
Hold this position in a stretch, continuing to focus on your breathing.
