I gave birth over 8 months ago. I didn't gain much weight and had no trouble losing the weight. However, my stomach muscles above my naval are still not back together. In fact they feel like they are the same distance apart as they were right after the birth. When I lay on my back and put my chin to my chest, there is quite a large gap in the muscles. I was doing crunches, sit ups, but wasn't seeing any results. Does anyone have any suggestions? I feel like this problem is contributing to my back problems. I really want to reconnect these muscles. Please help.
