The Energie Kegel exercise dumbell is a new product from Natural Contours. This ergonomically shaped barbell is especially effective for post-childbirth or menopause. The Energie Kegel exerciser is fairly heavy. It weighs 14 ounces. It is used while lying down on your back. It is inserted into the vagina and you use your kegel muscle to try to lift the barbell slightly. Before inserting the Energie kegel exerciser you might want to lubricate it. When you are finished your 5 minute exercises you should wash it with hot water and mild soap. With care, this item will last a lifetime.
