Can Pilates help strengthen your pelvic floor during pregnancy?

What are pelvic floor muscles?

Both men and women have a pelvic floor. It's made up of layers of muscles and connective tissues which support the bladder, bowel, (in women) uterus and (in men) prostate gland. These muscles attach to your pubic bone at the front and the tail bone at the back, as well as the base of the pelvis. They act as a 'sling' or 'hammock' to support the pelvic organs.

You can find your pelvic floor muscles and how you control them by going to the toilet. When urinating, try to stop the flow for a second. The muscles you use to do this are your pelvic floor muscles. However, it's important not to do this repeatedly because stopping the flow regularly can lead to urinary tract infections.

Why is strengthening your pelvic floor muscles important during pregnancy?

Pregnancy and childbirth put a strain on your pelvic floor muscles. During pregnancy, the pelvic floor muscles loosen due to hormonal changes. For example, the hormone relaxin relaxes the ligaments in the pelvic floor, softening and widening the cervix in preparation for birth.

In addition, your baby presses on your bladder as it grows, placing pressure on the pelvic floor and stretching these muscles. This can cause you to leak urine when you cough, laugh, exercise or sneeze. Constipation, which is a common problem during pregnancy, can also put a strain on the pelvic floor muscles.

"There is higher demand on the pelvic floor during pregnancy due to the growing baby. This additional loading can lead to the weakening and lengthening of the pelvic floor muscles," says Beth Davies, a personal trainer and coach specialising in pelvic health at Beth Davies Coaching.

"In addition to maintaining or building strength, it's also important to allow the pelvic floor muscles to relax too, especially at the later stages of pregnancy."

Benefits of strengthening the pelvic floor muscles

Exercising your pelvic floor muscles when pregnant can help your body cope with the increasing weight of the baby and with labour and birth. It can also help to heal the perineum - the area between the vagina and anus - after vaginal birth.

Strengthening the pelvic floor can also help to protect you from urine incontinence while pregnant and after your baby is born. In the long-term, it can also help to prevent a prolapse, which happens when your womb, bowel or bladder sag down and push against the walls of your vagina.

Can prenatal Pilates help to strengthen your pelvic floor muscles?

Pilates is a popular form of exercise which concentrates on strengthening the body with an emphasis on core strength. The aim of prenatal Pilates is to strengthen the muscles and improve posture, balance and flexibility. Pilates is also a good way to relax as it focuses on breathing exercises. Because it is a low-intensity form of exercise, it can be suitable for pregnant people.

Research suggests prenatal Pilates can help to prepare you for labour and birth by promoting relaxation, lowering blood pressure, increasing flexibility and easing back pain. Physical exercise in pregnancy - tailored to the abilities and needs of the pregnant person - can help to decrease the recovery time after birth. Prenatal Pilates may help to reduce the likelihood of perineal trauma during birth, such as tearing.

Strengthening the core and pelvic floor

"Pilates can be a useful and gentle form of exercise to help pregnant women strengthen their pelvic floor muscles and core to maintain good posture and mobility," says Davies.

"During pregnancy, the body's core - the team of muscles including the diaphragm, transverse abdominals, pelvic floor and multifidus (the muscles either side of the spinal column) can be challenged. This happens because of a changing centre of gravity, changes in posture and weight of the growing baby."

Pilates promotes a gentle engagement of the pelvic floor, so it is useful for pelvic floor awareness, improving tone and control, Davies says.

"Combined with strengthening movements, it can also maintain body strength," she adds. "As with any form of pregnancy exercise, moves that create lots of intra-abdominal pressure (such as planks and abdominal crunches) may be less appropriate as pregnancy progresses."

If you're a beginner, it can be a good idea to go to Pilates classes so an instructor can ensure you are doing the exercises correctly to avoid injury. Beginners and pregnant people can start with basic exercises that are tailored to their abilities.

How else can you exercise your pelvic floor muscles?

"Women may also benefit from isolated pelvic floor exercises called Kegels," says Davies. Once you've located your pelvic floor muscles, you can exercise them at any time by tightening and lifting the muscles. To do this, imagine squeezing as if to stop the flow of urine or as if to stop a poo.

Squeeze these muscles around ten times in a row, but make sure you have a rest afterwards. When you are used to doing the exercises, you can try holding the squeeze for a few seconds at a time every day. You can do pelvic floor exercises anywhere such as while you're waiting for the kettle to boil.
