Lie down on your back and pull both knees up to your chest.
Slowly pull the knees toward the shoulders until you feel the stretch in your lower back.
Keep your back flat on the mat. Release your shoulder blades down toward your waist. Broaden across your collar bones.
Draw your tailbone and sacrum down toward the mat, lengthening your spine even more.
Hold for up to one minute. Keep your breath smooth and even.
With an exhalation, release and extend both legs along the floor and rest.
