Insisting on levator ani exercise can restore the tension of pelvic floor muscles and prevent vaginal relaxation.
Clinically, it can prevent uterine prolapse or anterior and posterior vaginal wall bulging.
Therefore, especially women who give birth through vagina, insist on lifting anus until menopause.
The specific method is to contract the anus at rest 15 seconds, then slowly relax for five seconds, and do this for 30 times.
