Conscious efforts at good posture require some energy. You therefore burn some calories, however minute, in the process.
Breathing better is another advantage of good posture.
How to achieve good posture:
Make sure you are standing firmly on both feet. Gently feel your weight going into the ground while your body is growing taller. This should cause you to be straight and you should feel your abdomen gently pulling in as a result. Your shoulders should not be hunched forward or pulled too far back. They should rest easy on top of your body. The head should lift up from the spine but not pull. The neck should feel free. Make sure your knees are not locked and your joints are free.
When sitting, make sure your back is straight and your feet are firmly placed on the ground. Your hips should be as far back in the chair as possible and your weight should be equally distributed between both of your hips.
Do not spend all day slouched in front of your desk or computer. Take standing breaks every couple of hours. When working on your computer or any other screen, sit straight up, your eyes should be on the same level as the middle of the screen to avoid back and neck pain.
If you are just beginning to improve your posture, allow time for your muscles to adjust to the change. It may seem uncomfortable at first, but you will soon notice the benefits of standing and sitting properly.
