The most effective reduction exercise is pelvic floor muscle rehabilitation training, also known as Kegel template training, which helps to restore vaginal laxity by placing two electrodes in the vagina and abdomen, and observing the two electrodes under a computer, which undergo rhythmic movements due to the impact of external forces, thus improving the effect of the reduction exercise and helping to restore vaginal laxity. The reduction exercises are a more comprehensive treatment and can be consolidated by doing anal lifting exercises and vaginal dumbbell training, all of which are more effective. Most of the vaginal laxity is caused by the large fetus during vaginal delivery, which compresses the vagina for a longer period of time and causes the vaginal muscles to relax and decrease in elasticity, and by exercising too early after delivery or doing exercises to increase abdominal pressure.
