The pelvic floor is also called the pelvic diaphragm.

A weakening of the supportive muscles and ligaments of the pelvic floor, this condition, which affects women causes the pelvic floor to sag and press into the wall of the vagina.

Pelvic floor exercises are done to help strengthen your pelvic floor muscles. These are the muscles you use when you stop and start urination.

The exercises are easy to do just contract your muscles as if you were trying to stop peeing and release again.

Some people find these muscles hard to control and may use a pelvic floor toner which does the exercises for you.

The pelvic floor normally holds the uterus and the bladder in position above the vagina. When the pelvic floor becomes stretched/damaged, these organs can sag into the vagina, sometimes bulging out.
