After 3 months
I have gone through your question and understand the concerns.
Post caesarean section
, heavy exercises like crunches and sit ups should be started after 3 months of the procedure.
This is the time in which the abdominal muscles heal properly and gain their original strength.
If muscles are strained earlier, then they may give away leading to hernia
I will suggest you to start exercises at 3 months after caesarean section.
Hope you found the answer helpful.
