Standing with your arms down at your side, point your thumbs out to the front and make a fist. Slowly rotate your arms so your thumbs are pointing out to your sides while pushing out your chest. Then, rotate back past the original position so your thumbs are pointing backward. You should feel this across your chest and in your shoulders. Being in the riding position for long periods of time can leave us tightened up into a position with our shoulders pressed inward. This stretch can feel great after a long day of touring.
