The short answer is yes - except under supervision, and no - because they can actually really help when done well.
Let me explain:
Crunches are one of the 12 exercises I use to close the gap in my core and pelvic floor program.
When they're done well, our diastasis recti closes.
When they're done badly, it actually opens it more.
If you've ever assessed the gap yourself you've probably used a crunch to do it, so you've seen it for yourself!
Most exercises are not good or bad in themselves - it's all about why you're doing it, and most importantly, HOW.
