Fact: Pregnant women often say this. In fact, childbirth is a lot easier if the muscles are appropriately prepared. Strong and flexible muscles can expand more, so tears are less likely to occur. Also, exercising may help prevent pelvic organ prolapse, vaginal laxity (and the flatulence that accompanies it), stress incontinence and haemorrhoids.
If you are pregnant you are likely to be fully focused on the baby but it’s important to care about your own body too. PF exercises only take a few minutes a day, so don’t put it off.
