Postpartum recovery involves more than just resting; for many women, it requires addressing the physical separation of the abdominal muscles. This condition, known as Diastasis Recti Abdominis (DRA), affects up to 60% of people who become pregnant [1]. While the body naturally adapts during pregnancy by stretching the “six-pack” muscles (rectus abdominis) to accommodate a growing baby, the tissue connecting them—the linea alba—can lose its tension, leading to a visible bulge or “pooch” that persists months after delivery.
While some cases resolve spontaneously, research indicates that approximately one-third of women still experience DRA one year after childbirth without targeted intervention [2]. This guide outlines the evidence-based exercises and safety protocols necessary to restore core functional integrity.

Identifying Diastasis Recti
Before starting a rehabilitation program, it is essential to identify the severity of the separation. DRA is typically characterized by a soft gap or a vertical ridge that appears when contracting the abdominal muscles.
Common signs include:
A visible bulge or “coning” near the belly button when sitting up.
Persistent low back pain or pelvic floor dysfunction.
Difficulty engaging the core during daily activities [2].
Feeling a gap wider than two finger-widths between the abdominal bands.
You can perform a self-check by lying on your back and feeling for a gap between your abdominal bands; a separation wider than two finger-widths is generally classified as DRA. Other indicators include a visible ridge or ‘coning’ when you engage your core or sit up.
Beyond the visible bulge near the belly button, individuals often experience persistent lower back pain, pelvic floor dysfunction, and a general difficulty engaging their core muscles during daily physical activities.
The Science of DRA Rehabilitation
Recent clinical evidence published in Scientific Reports highlights that combining deep abdominal training (transverse abdominis) with superficial muscle training is significantly more effective than single-muscle exercises [3]. The goal is not just to “close the gap” but to improve the tension-loading capacity of the linea alba.
No, the primary goal is to improve the tension-loading capacity of the linea alba and restore functional integrity. Modern research suggests that the ability of the connective tissue to manage pressure is more important than the width of the gap itself.
Clinical evidence shows that combining deep transverse abdominis training with superficial muscle exercises is more effective for healing. Targeted deep core work helps stabilize the midline and reduces the inter-recti distance more efficiently than surface-level exercises alone.
Safe Exercises for Postpartum Recovery
The following exercises focus on “drawing-in” maneuvers and pelvic floor coordination, which are proven to reduce the inter-recti distance (IRD) [4].
1. Diaphragmatic Breathing
This is the foundational movement for all core rehab. It re-establishes the connection between the diaphragm and the pelvic floor.
- How-to: Lie on your back with knees bent. Place one hand on your chest and one on your belly. Inhale deeply through the nose, ensuring the hand on your belly rises while the chest remains still. Exhale slowly through pursed lips [5].
2. Pelvic Tilts
Pelvic tilts gently engage the lower abdominals without putting excessive intra-abdominal pressure on the midline.
- How-to: Lie on your back with knees bent. Flatten your lower back against the floor by tilting your hips toward your ribs. Hold for 3–5 seconds and release.
3. Heel Slides
This exercise focuses on the transverse abdominis, the deepest layer of the core.
- How-to: While lying on your back, slowly slide one heel away from your body until the leg is straight, then pull it back. The key is to keep the lower back glued to the floor throughout the movement [1].
4. Bird-Dog
This movement improves stability and core coordination.
- How-to: Start on all fours. Simultaneously extend the opposite arm and leg, keeping your back flat like a table. Avoid letting your belly “hang” toward the floor; keep it tucked in [2].
Diaphragmatic breathing re-establishes the essential connection between the diaphragm and the pelvic floor. It allows you to engage the deep core without creating harmful internal pressure that could worsen the abdominal separation.
Heel slides specifically target the transverse abdominis, which is the deepest layer of the core. By keeping the lower back flat while moving the legs, you build the strength necessary to support the abdominal wall and the linea alba.
Exercises to Avoid
Performing the wrong movements can worsen the separation by increasing internal pressure that pushes against the weakened linea alba [5]. Switch to these therapeutic alternatives and remember that just as you might research different types of anesthesia used during surgery to understand risks, you must understand the risks of improper exercise.
Avoid the following until cleared by a specialist:
Crunches and Sit-ups: These create “coning” and put direct pressure on the gap.
Planks and Push-ups: The weight of the internal organs pressing down against the abdominal wall can prevent healing.
Heavy Lifting: Straining can cause the abdominal wall to bulge outward.
| Avoid (High Pressure) | Safe Alternative |
|---|---|
| Crunches & Sit-ups | Diaphragmatic Breathing |
| Full Planks | Bird-Dog (Quadruped) |
| Leg Drops | Heel Slides |
| Heavy Lifting | Pelvic Tilts |
Crunches create direct outward pressure and cause ‘coning’ at the site of the separation, which can stretch the weakened tissue further. These movements prioritize superficial muscles that often exacerbate the abdominal gap rather than healing it.
Planks should generally be avoided in the early stages of recovery because the weight of your internal organs presses down against the weakened abdominal wall. This downward pressure can prevent the linea alba from healing and may increase the severity of the bulge.
When to Consider Surgery
If 6–12 months of consistent physical therapy do not resolve the bulge or if a hernia develops, surgical options like an abdominoplasty (tummy tuck) may be considered. Surgery is generally viewed as a last resort for functional restoration or for those seeking immediate aesthetic results after significant tissue stretching [5]. It’s important to weigh these options carefully, much like you would when reviewing a financial guide for birth control implants.
Surgery is typically considered a last resort if 6 to 12 months of consistent, targeted physical therapy fail to resolve the bulge or functional issues. It may also be necessary if a hernia develops alongside the muscle separation.
An abdominoplasty, commonly known as a tummy tuck, is the standard surgical procedure to repair DRA. It involves physically suturing the abdominal muscles back together to restore the core’s structural integrity and aesthetic appearance.
Summary of Key Takeaways
Prevalence: DRA affects roughly 60% of postpartum women, with 33% still experiencing symptoms a year later without exercise.
Mechanism: Healing requires strengthening the deep transverse abdominis rather than just the superficial “six-pack” muscles.
Safe Movements: Focus on diaphragmatic breathing, pelvic tilts, and heel slides.
Risk Factors: Avoid crunches, planks, and heavy lifting, which can increase the gap.
Action Plan
- Check for DRA: Perform a self-assessment or visit a pelvic floor physical therapist.
- Daily Breathing: Practice diaphragmatic breathing for 5–10 minutes daily.
- Low-Impact Strengthening: Incorporate pelvic tilts and bird-dogs 3 times per week.
- Monitor Progress: Use a mirror to watch for “coning” or “doming” during exercise; if it occurs, stop that specific movement.
While recovery requires patience, a structured exercise program effectively restores core strength and prevents long-term complications like back pain and incontinence.
| Category | Key Recommendation |
|---|---|
| Diagnosis | Internal gap > 2 finger-widths or visible coning. |
| Primary Goal | Strengthen deep Transverse Abdominis (TvA). |
| Core Exercises | Breathing, Pelvic Tilts, Heel Slides, Bird-Dog. |
| Timeline | Consistent PT for 6–12 months before considering surgery. |
While some cases resolve naturally, research shows that approximately 33% of women still experience symptoms one year after childbirth if they do not perform targeted exercises. Early intervention is key to ensuring the connective tissue regains its strength.
You should monitor your abdomen for any ‘doming’ or ‘coning’ during exercise. If you see the midline bulging outward, it means the exercise is too strenuous for your current core strength and you should stop or modify the movement.
