I have written about the diastasis warning sign before but it's such a good method to find out if you are pushing yourself too hard and are actually making your abdominal muscles split - diastasis recti - worse - instead of activating your abdominals properly and healing your post-pregnancy belly.
If you are performing an exercise which is challenging to the core creating a lot of abdomen pressure, let say a plank, just look down at your belly and notice the shape of it. Is it flat and strong (aside from some loose skin hanging down) or is it pushed out, almost shaped as a volcano or a pyramid? Well, if that's the case and you simply aren't capable of performing the plank without this is happening, that's a good warning sign of diastasis recti and of you not being able to control your abdominals.
