The correct way to contract the pelvic floor 1. Lie down with your knees bent. 2, inhale, tighten the muscles around the vagina and the anal opening (anal lifting action) 3, tighten the urethra, vagina and anus (they are supported by the pelvic floor muscles at the same time), the feeling is like holding the stool, holding urine when the action. 4.Close your breath and keep the pelvic floor muscles contracted for five seconds, then slowly relax, and after five to ten seconds, repeat the contraction again. Breathe as usual during the exercise and keep the rest of the body relaxed. Touch the abdomen with your hand, if the abdomen has the phenomenon of tightening, it means that the movement is wrong. The purpose of pelvic floor training is to exercise and strengthen the muscles that support the bladder, vagina, uterus, rectum and other organs, stretching and contracting to prevent incontinence, organ prolapse and vaginal laxity.
