Hi Tan

I have that problem as well and my physio told me to do sit ups with my arms crossed over my stomach area kind of like holding the stomach together IYKWIM and not to come right up but to do more like a crunch (she said to cross my arms and hold/rest my hands on the side of my stomach/hip area). I am not sure if it works as I am yet to start doing them - I feel very guilty that I havent started yet. Now that you have made me think about it I might have to get into it!
Good luck
I will be interested to see if there are any other ways of addressing this issue!
