When you are doing Exercise Ball Ab Workouts, there are certainly benefits that you reap which you would not have ordinarily seen while using other regular gym equipments. One such advantage of using the exercise ball is that you can perform basic crunches with the ball and be using it to support the lower back. In the process of this workout, all you must remember is to avoid sitting on the ball and leaning backwards. You may actually fall over and add embarrassment to all your gym woes if everyone starts laughing at you. Think of the ball as a high cushioned chair sofa and sit relaxed on it as you would, putting your arms behind your neck. After this just lean back and forth just as you do with regular AB crunches. Just do about ten as a set then repeat many times as you get used to it.
