Begin with your forearms together above your chest

To begin this stretch.  Lie on your roller with your body supported from your tail bone to the top of your head.  Inhale: squeeze your forearms together to engage your chest muscles.

Exhale: open your arms out to the side of the room. Keep your elbows bent to avoid hyper-extending the elbows.

Open the arms out to your sides keeping your ribs down

Remember to hold the position and take at least three full breaths inhaling and exhaling.

This is a great stretch to open your chest and perhaps even improve your breathing. I recommend it for anyone you sits behind a steering wheel or a computer for more than 3 hours a day. As these activities tend cause you to hunch over and shorten your chest muscles.  This is also good for post natal women who are leaning over their newborns and/or breastfeeding.  Careful of your balance.
