To be fair, this is something I have only recently realised, someone posted a link which showed how you could tell if your abdominal muscles had knitted back together post pregnancy and I found that I can fit two fingers between the walls of the muscles all the way down, I haven't done any abdominal exercises since birth, my main exercise has been a lot of walking. I have a little bit of a loose tummy, but wasn't letting it bother me too much.
Anything that can be done through exercise? and any particular exercises that people can recommend? or is it a case of see the doctor and get physio?
