My tummy muscles are still separated. After having DS it was about 2-2 1/2cm's wide, so it has closed up a bit. DS is 7mths now and with DD my separation wasn't so big and it was gone by this stage, just with walking and normal day to day stuff. At the moment, I still have a gap of about 1/2-1cm just above my belly button, and up a little bit towards my ribs. I have been trying to suck my belly in and have good posture, but my muscles are really weak still. I read somewhere that crunches are not reccomended for tummy muscle separation after pregnancy. What other exercises can I do to get my belly strong again??
