So now that you know what to check for - how do you measure up? Anything over 2 and a half fingers is considered a big gap and you should avoid any exercise which forces your stomach to push outward (e.g. sit ups and crunches and even planks put too much pressure on the Diastasis). Just as a side note - I reckon you should avoid the first two anyway because if not performed correctly you can do more damage than good.
So what core exercises can you do? The good news is that just because you have Diastasis Recti doesn't mean that you have to sit out during the ab set. You just have to do exercises that will help your gap.
Here are my top tips for Diastasis Recti: (And it's an ongoing list - every day I'm finding more information! If you have any questions or anything to add to the list- drop me a line.)
I hope the information was helpful! If you have any questions - don't hesitate to give me a call.
PS: Here's a video with a few exercises that will help close the gap.
