1. Lie on your back with your knees bent and your feet about hip-width apart.
2. Tuck your chin, and relax your shoulders.
3. Reach your arms straight out to the sides. If you don't feel a mild stretch in your shoulders and across your chest, use a foam roll or a tightly rolled towel or blanket under your spine, from your tailbone to your head.
4. Relax in this position for at least 15 to 30 seconds. Continue to breathe normally and don't hold your breath.
5. Repeat 2 to 4 times.

As you get used to this stretch, keep adding a little more time until you are able to relax in this position for up to 5 minutes. When you can relax for at least 2 minutes, you only need to do the exercise 1 time per session.
