For those who have never heard of Kettlebells, they are weighted balls with handles on the tops, and they are often thought to have originated in Russian training facilities. Either way, these simple devices are often made of cast iron and can be used to do multiple exercise routines. And while the most common of these routines, the basic kettlebell swing, is often thought of as an arm workout, it also implicates the muscles of the midsection, making it a potentially effective way to flatten tummy muscles.
To use Kettlebells correctly for the kettlebell swing, one starts by standing upright with legs spread about shoulder width apart. Holding the kettlebell with both hands, the individual performs what amounts to a squat. In the upward motion of the squat, the individual swings the kettlebell upward, at least until the arms are extended perpendicular to the torso, if not a little higher. Again, while this workout does implicate the arm and leg muscles, it should also help to flatten tummy areas. Whether or not they notice it at first, individuals who exercise in this way with Kettlebells are relying partly on their abdominal muscles in order to complete the swinging motion, and thus they are working them.
