CORRECT YOUR POSTURE:The HEMJEX Advanced Posture Corrector is ergonomically designed to discreetly and comfortably give you support. We suggested wearing the support for 20 minutes a day the first week. If you are comfortable then we suggest you increase that time by 20 minutes every week, until you are completely comfortable wearing the corrector up to 2 hours every day. CHECK YOUR SIZE BEFORE BUYING | The HEMJEX Posture Corrector-designed for chest circumference: 34-48 inches. LONG TERM CORRECTIVE BENEFITS- We don’t want you to wear your posture corrector forever! The Careworth Posture Corrector promotes strengthening muscles and aligning your spine so that you can now stand up straight with your shoulders back, even when not wearing your brace!
