One of the most talked about stomach fitness equipment is the Ab King Pro. Like many , this piece of equipment has an elaborate and well crafted infomercial which makes pretty bold claims. The Ab King Pro isnt really an abs machine since its basically a workout bench with a bar you can grab with your arms. You just lie on the bench, grasp the bar handle, and place your legs on the floor or on the foot rest. What you can do with this machine are basically crunches, either for your main stomach muscles or for your oblique in a similar way to what you would do when lying on the floor. Your neck is supported on the bench, but your lower back isnt because it breaks away from the bench when youre doing the crunch. The infomercial claims that in just 3 minutes of workout a day (combined with regular exercise and a sensible diet) youll in days.
