Review on Adjustable Posture Corrector for Women and Men - Upper Back Brace for Clavicle Chest Support, Neck, Back and Shoulder Straight - Size S 27-32 Inch by Ben Daugherty

So when you correct your posture you must actually train/develop using your muscles to maintain your posture. This corrector is not meant to be just a crutch that will support your body forever. This will help your body adjust to the feeling of being upright with your arms back, allowing you to straighten the front of your chest. Then you'll find that when your chest is inflated and your shoulders are rotated to the side, not in front of your body (roll forward), it's neither strange nor necessary to be unsteady! To be honest, I've been wearing this for a long time. the first time and less and less since then. After getting used to the feeling of sitting upright, my body now prefers to be upright rather than curled up. My body has learned to recognize when it is slouched because my shoulders or neck are becoming more and more responsive to the pain of poor posture. up to 30 minutes or the recommended time. Otherwise, your armpits will hurt due to insufficient blood flow.
