somewhere along the line at being a kid and teenager I started sucking in my stomach and tightening my abdominal muscles to help build muscle even when I wasn't exercising. Fast forward to today I naturally suck in my stomach even when I'm not trying to and I am 17 weeks pregnant and I am trying to break the habit. every once in awhile I'll be conscious of the fact that I am sucking it in and I'll relax, does anyone have any tips on breaking this bad habit??
