The abdominal contour is govern by three factors: 1. Anatomy: Intra-abdominal contents including fat, functional muscle in its appropriate anatomical location, amount and distribution of fat, and amount and quality of skin. 2. Muscle function affected by hernias or denervation. 3. Muscle tone and posture. If you have a anatomical problem with the muscle such as hernia, weakness, or diastasis, surgical correction or tightening might help but this is dependent on the relative contribution of the other anatomical componentssuch as intra-abdominal and extra-abdominal fat. If your muscle is normal, but you have poor posture and resting tone, only you can train yourself to correct this. Contouring by muscle tightening will be limited by poor posture and this should be analysis prior to surgery.
