This exercise is to strengthen pelvic floor muscles and may be enough to limit symptoms of prolapse.
An exercises known as "Kegel exercises" are an excellent way to increase your pelvic support. To perform Kegel exercises, you need to squeeze the pelvic floor muscles that you would use if you were trying to hold back urine or trying to stop urinating when your bladder was only partly empty. Most doctors advise women with pelvic muscle weakness to tighten these muscles and hold them tight for a few seconds at a time. Repeat the exercise ten times in each session and do approximately four sessions each day. Over time, most women notice improvement in bladder control and may have less pain or fewer symptoms.

Exercise -- Special exercises, called Kegel exercises, can help strengthen the pelvic floor muscles. This may be the only treatment needed in mild cases of uterine prolapse. To do Kegel exercises, tighten your pelvic muscles as if you are trying to hold back urine. Hold the muscles tight for a few seconds and then release. Repeat 10 times. You may do these exercises anywhere and at any time (up to four times a day).
