Kegel exercises (also called PFE - pelvic floor exercises), named after Dr. Arnold Kegel, strengthen the pubococcygeal muscle and other muscles of the pelvic diaphragm. Research shows that Kegels can help men achieve stronger erections and gain greater control over ejaculation. Benefits for women include: easier and more intensive orgasms, easier childbirth, prolapse and incontinence prevention, and tighter and more toned vaginal muscles. The application helps you perform the exercises properly, by showing exactly when and for how long you should clench and relax your muscles. You can set your own exercise durations and number of repetitions.
