The “pelvic floor” refers to a group of muscles that attach to the front, back, and sides of the pelvic bone and sacrum (the large fused bone at the bottom of your spine, just above the tailbone). Like a sling or hammock, these muscles support the organs in the pelvis, including the bladder, uterus or prostate, and rectum. They also wrap around your urethra, rectum, and vagina (in women).
Your pelvic floor is the group of muscles and ligaments in your pelvic region. The pelvic floor acts like a sling to support the organs in your pelvis — including the bladder, rectum, and uterus or prostate. Contracting and relaxing these muscles allows you to control your bowel movements, urination, and, for women particularly, sexual intercourse.

Hip bridges: Engage your abdominals and pelvic floor before you start to bridge up, then bring the hipbones up to the sky. Then hollow out even more and really engage the pelvic floor. Then slowly lower your back to the mat, starting with your upper back, middle back, then lower back. Once you reach the mat, you can release your pelvic floor, and then re-engage as you do this move again.
Increases bladder and bowel control. The pelvic floor muscles are directly responsible for controlling urine and bowel movements. If these muscles are weak, you’re more likely to experience constipation, urinary incontinence, struggle to control flatulence, or experience urine leakage from forceful activities like when sneezing, coughing, or laughing (called “stress incontinence”). Strengthening your pelvic floor can improve your bowel and bladder control.
