Keep both your arms straight in front of your eyes. Stand straight and now bend your back half the way from your waist and inhale. Now come up and slowly exhale. Practice this at least five times a day. This is called good morning exercise but it's just the name it can be done any time in the day with light stomach.
Shrug your shoulders up and slowly take them down. Practice it for 10 counts everyday. It even relaxes the shoulder muscles.
Push a wall in front of you with both your arms and keeping your back straight.
