The use of a stone egg to strengthen the vagina is a practice that evolved in ancient China. As time went on, the secret of the practice remained in the Royal Palace and was taught only to the queen and concubines. Many who mastered the technique experienced very good health, remaining young and bountiful with sexual organs in old age as tight and resilient as those of a young, unmarried lady. Some believe that the queen and concubines practiced the techniques in order to please the king while making love. The Egg exercises and Vaginal Weight Lifting were implemented for improving physical health, since these exercises provide more power to the Chi muscle, which is also called the Kegel muscle or the Love muscle; (Pubococcygeous, is the anatomically correct name for this muscle, or for short just called the P.C. muscle).
