Stomach crunches or sit- ups tend to miss the transverse abs. There's more pain but lesser glory. So if you want an effective abdominal fitness regime, you may try Pilates which include exercises that target the transverse area. You can also try to hold your stomach in or keep a straight back to tighten the muscles of your abs. Regular diligence and diet will make you look like Eva Langoria of the Desperate Housewives while you hit the street with renewed confidence and self-esteem from having a sexy body.
