Obstructed Defecation: Obstructed defecation is difficulty getting bowel movements out of the body. Although the stool reaches the rectum, or bottom of the colon, the patient has difficulty emptying. This often makes patients feel that they need to go the bathroom more often, or that they cannot empty completely, as if stool remains in their rectum. Obstructed defecation may be caused by pelvic floor prolapse (discussed below), pain symptoms or muscles not functioning normally. 
Pelvic Floor Prolapse: The pelvic floor consists of the muscles and organs of the pelvis, such as the rectum, vagina, bladder. Stretching of the pelvic floor may occur with aging, collagen disorders or after childbirth. When the pelvic floor is stretched, the rectum, vagina, or bladder may protrude through the rectum or vagina, causing a bulge, which can be felt. In addition to a rectocele, patients may have rectal prolapse, a cystocele (prolapse of the bladder) or protrusion of the small bowel. Symptoms generally include difficulty in emptying during urination or defecation, incontinence or pressure in the pelvis.  

Reduces the chances of pelvic organ prolapse. Pelvic organ prolapse is a health condition in which the pelvic floor muscles are so weak that they can’t support the pelvic organs (bladder, cervix, uterus, and rectum). During a pelvic organ prolapse, one or more of the pelvic organs falls down into the vagina, creating a bulge. Since pelvic floor exercises strengthen the pelvic muscles, they can help prevent the muscles from becoming too weak and allowing prolapse.
