Ever just wanted to stand up and scream: we have the solution. For the next 5 minutes do this: Stretch your arms up to the sky and bring them back down in a circle, keep this going. At the same time breathe in as your raise  hold for 4 counts and exhale as you lower, if your on your own exhale with a sound(we like arrgghh) Voila feeling refreshed? Now continue your day.
