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.
Lift your hips off the mat, and roll back and forth, pushing with your legs.
As you roll back and forth drop your upper back towards the floor arching your back.
Continue to focus on your breathing.
