Effective exercise of pelvic floor muscle function: Kegel exercise improves the function of pelvic floor muscles by contracting and relaxing the muscle groups in the pelvic floor, and is recognized as a method to prevent and improve female pelvic floor organ prolapse, vaginal relaxation, and urinary incontinence. When standing, if the pelvic floor muscles exert half or less of the maximum force, it is appropriate to clamp the ball. When standing, it won't have a significant impact, and some people can't feel the presence of Kegel balls, so this kind of force is also suitable. when the Kegel balls are inserted, they must be able to speak normally without excessive force.
