Diastasis recti is the separation of your 6 pack abdominal muscles. It often occurs in pregnancy but can also occur in men from improper lifting and workout techniques. If the 6 pack abdominal muscles aren't able to expand as the baby grows, the small cartilage connecting the two sides can separate. It is measured in centimeters or fingers. It’s usually painless and can be fairly common occurring in ‘cross fit moms’. It’s why we don’t recommend crushes and sit ups in pregnancy. It’s also why we always recommend that you turn to one side and use your hands to help you sit up rather than lurching forward from laying back.
You can check if you have diastasis by laying down, lifting your head and shoulders to engage abs and feeling along the line of your 6 pack abs.
If you have a separation, wearing a belly band and doing the belly pull exercises can help reduce the separation. It’s important to do so because the separation weakens your core and can cause low back pain and hip pain but also potentially a malpositioned asynclitic baby that could make labor more challenging.
Separation is treated postpartum with targeted exercises to knit the abdominal muscles back together. Make sure to get the help of a specialized PT before you start your regular workout because you again want to make sure to avoid sit ups and crunches until the dialysis has healed.
