New moms may spend months planking and doing core work only to find the same soft ridge still running down the middle of the belly. That ridge is usually diastasis recti, a separation of the abdominal muscles caused by pregnancy that targeted exercise often can't undo. Once the connective tissue between the muscles, called the linea alba, loses its elasticity, core training alone rarely brings it back. A tummy tuck fixes the problem directly, by surgically repairing the abdominal wall itself.
Michael R. Burgdorf, MD, MPH is a board-certified plastic surgeon and the founder of Music City Plastic Surgery in Nashville, where he has helped thousands of mothers reclaim their pre-pregnancy shape through his signature Mommy Makeover approach. Here's why workouts alone often fall short, and how Dr. Burgdorf repairs the separation surgically.
The Muscle Separation Exercise Can't Close
During pregnancy, the growing uterus pushes against the rectus abdominis, the two muscles that run down the front of the stomach. That pressure stretches the linea alba, the connective tissue between them, and pulls the muscles apart. According to Cleveland Clinic, about six in ten women experience this after childbirth. Many women see the gap close naturally within a few months. For others, it stays open, and the belly keeps its post-pregnancy bulge no matter how consistent their workouts are.
Signs Diastasis Recti Might Be at Play
Patients often notice a few symptoms together:
- A dome-shaped bulge above or below the belly button, especially when sitting up or straining
- Persistent lower back pain unrelated to injury
- A midsection that feels weak or unsupported during everyday movement
- Abdominal fullness that resists diet and exercise
This combination usually points to muscle separation. Cardio and ab work strengthen the muscles but can't close the physical gap between them, so results often stall despite consistent effort.
Why a Tummy Tuck Succeeds Where Workouts Stop
During a tummy tuck, Dr. Burgdorf sutures the separated rectus muscles back together, giving the abdominal wall the support it lost during pregnancy. Excess skin is then removed, and the remaining tissue is re-draped for a smoother, natural-looking contour. Because the repair addresses the muscle and connective tissue directly, it holds in ways exercise alone typically cannot.
Every procedure takes place in Music City Plastic Surgery's AAAASF-accredited surgical suite, and many patients pair muscle repair with liposuction or breast surgery as part of a complete Mommy Makeover.
Recovery Without Guesswork
Most patients walk within hours of surgery and resume light activity within a few days. Swelling continues to settle over the following months, and Dr. Burgdorf schedules follow-up visits at regular intervals to confirm the repair is holding as expected.

Diastasis recti is a physical separation that pregnancy causes, and for many patients, surgical repair may be the most effective way to close it. With board certification from the American Board of Plastic Surgery and years spent helping Nashville mothers reclaim their pre-pregnancy shape, Dr. Burgdorf can help determine whether a tummy tuck fits your goals.
