Most of us got the memo that “sitting is the new smoking”. Chronic sitting, especially with poor posture, slumped over a laptop, iPhone or other piece of posture-wrecking technology, causes tightness in the hips, pectorals and several muscles that internally rotate the shoulders. Those tight muscles can pull joints out of alignment and cause pain and stiffness in the back, neck and legs and give you that oh so chic Hunchback of Notre Dame look. Not healthy. Not cute. But you can make some simple yet impactful lifestyle changes that will have you looking and feeling healthy and confident.
