How to Improve Your Standing Posture: If I had to tell you one "switch" tip, it is simply to "stand tall" whenever you think about it. The muscles that you use to stand taller are exactly the same muscles that improve your posture. Stand tall! Think tall neck (ballerina or model style)- but keep your chin tucked in. Avoid tilting your head forward, backward or sideways. Your earlobes will line up with the middle of your shoulders. Keep your shoulders back, your knees straight and your back straight. Let arms hang naturally down the sides of the body Lightly draw in your core stomach muscles. Avoid tilting your pelvis forward. Avoid locking the knees Ensure your feet arches are in a neutral (not flat) position. Stand with weight over the centre of your feet. Stand with your feet slightly apart (shoulder-width). Shift your weight from one foot to the other when standing for a sustained periods. Alternatively, stand in a walk-stand and rock your weight from your front to back foot.
