The three-month postpartum period after birth is often called the “fourth trimester.” It’s a time of immense change, incredible joy, and profound challenges. While so much focus is on the new baby, the mother is undergoing her own monumental transition — physically, hormonally, and emotionally. The pressure, both internal and external, to “bounce back” is immense. But your body doesn’t need to bounce; it needs to heal. It needs to be honored for the incredible feat it has accomplished.
This comeback plan is not about getting your old body back. It’s about getting to know and build a new one — one that is strong, resilient, and capable of meeting the physical demands of motherhood. This is your gentle guide to rebuilding your core from the inside out, focusing on healing, reconnection, and foundational strength.
The Biology of Your Postpartum Body
To heal effectively, we first need to understand what has happened to your body. Pregnancy and childbirth, whether vaginal or via C-section, are significant musculoskeletal events. Let’s explore the key players in your postpartum recovery.
The Deep Core System
Think of your core not as a six-pack, but as a muscular canister. The top is your diaphragm (your primary breathing muscle), the bottom is your pelvic floor (a hammock of muscles that supports your organs), the front and sides are your transverse abdominis (TVA), a deep corset-like muscle that stabilizes your spine, and the back is your multifidus, a series of small muscles running along your spine. During pregnancy, this canister was stretched and placed under immense pressure. Effective recovery is about teaching these four components to work together in harmony again to manage intra-abdominal pressure—the pressure inside your abdominal cavity that increases when you lift, cough, or exercise.
Diastasis Recti (Abdominal Separation)
To make room for your growing baby, the connective tissue that runs down the midline of your abdomen, the linea alba, stretches and thins. This creates a separation between the left and right sides of your rectus abdominis (the “six-pack” muscle). This is diastasis recti, and it is a completely normal and necessary part of pregnancy. The goal post-pregnancy isn’t necessarily to “close the gap” completely, but to restore tension to the linea alba so that your core can effectively transfer load and manage pressure, preventing that “coning” or “doming” appearance in your belly.
The Pelvic Floor
Your pelvic floor muscles have been under the equivalent of a nine-month marathon, bearing the increasing weight of your uterus, and then undergoing the intense stretching of childbirth. This can lead to weakness, tightness, or a lack of coordination, resulting in issues like urinary incontinence (leaking when you cough, sneeze, or jump), pelvic organ prolapse, or pain. Healing this crucial muscle group is a cornerstone of true core recovery.
The Hormonal Shift
During pregnancy, your body produces the hormone relaxin, which does exactly what it sounds like—it relaxes your ligaments and joints to allow the pelvis to expand for birth. Relaxin can stay in your system for several months postpartum, especially if you are breastfeeding. This means your joints are less stable, making you more susceptible to injury if you return to high-impact or heavy exercise too soon.
This comeback is about re-establishing the neural pathways—the mind-muscle connection—to these deep core muscles. It’s about teaching your body a new, more functional strategy for movement, starting with the very foundation of movement: your breath.

The 6-Week Gentle Comeback Plan
Important Note: Before starting this or any postpartum exercise program, you must be cleared for exercise by your doctor or midwife, which typically happens at your 6-week postpartum check-up. Listen to your body above all else. Pain is a signal to stop. If you experience any pain, increased bleeding, or feelings of pelvic heaviness, stop and consult your healthcare provider.
The Foundation | Healing Before Strengthening
This plan is built on a “bottom-up” approach. We start with the deepest, most foundational layers—your breath, your pelvic floor, and your deep abs—before moving on to more traditional “core” exercises.
Weeks 1-2: Reconnection & Activation
Goal: The focus of these first two weeks is purely on re-establishing the mind-muscle connection with your deep core and pelvic floor. We are not aiming for fatigue or a “burn.” We are simply reminding your brain how to communicate with these muscles.
The Exercises: Perform this sequence once a day.
- Connection Breath (360 Breathing): This is the single most important exercise in your recovery. It retrains your diaphragm, pelvic floor, and TVA to work as a team. Lie on your back with your knees bent and feet flat on the floor. Place your hands on your lower ribs.
- Inhale: Breathe in slowly through your nose, allowing your rib cage to expand 360 degrees—to the front, sides, and back—into your hands. Feel your belly rise gently and your pelvic floor muscles relax and lengthen.
- Exhale: Exhale slowly through your mouth as if you’re blowing through a straw. As you exhale, feel your pelvic floor gently lift (like you’re picking up a blueberry with your vagina and anus) and your deep abdominal muscles gently draw in and up, hugging your spine.
- Perform 2-3 sets of 10-15 deep, intentional breaths. This exercise is about coordination, not force.
- Pelvic Tilts: Lying in the same position, place your hands on your hip bones. Using your connection breath, inhale and let your pelvis relax, allowing a small arch to form in your lower back. As you exhale and engage your TVA and pelvic floor, gently flatten your lower back against the floor by tilting your pelvis toward your rib cage. The movement should be small and controlled, initiated by your deep abs, not by squeezing your glutes.
- Perform 2 sets of 15-20 repetitions.
- Heel Slides: Staying on your back, begin with your connection breath. On an exhale, engage your core and slowly slide one heel away from you along the floor until the leg is straight, ensuring your pelvis remains stable and your back doesn’t arch. Inhale as you hold the extended position. Exhale and use your core to gently slide the heel back to the starting position. This exercise challenges your TVA to stabilize your pelvis while your limbs are moving—a key function for daily life.
- Perform 2 sets of 10-12 repetitions per leg.
Weeks 3-4: Building Foundational Stability
Goal: Now that the connection is re-established, we will start to build endurance in those deep core muscles and introduce movements that challenge your stability in a safe, controlled way.
The Exercises: Perform this sequence 3-4 times per week.
- Connection Breath Warm-up: Always start with 1-2 minutes of connection breathing.
- Glute Bridges: Lie on your back with knees bent, feet flat on the floor about hip-width apart. On an exhale, gently engage your core and lift your pelvic floor, then press through your heels to lift your hips off the floor until your body forms a straight line from your shoulders to your knees. Avoid arching your back; the work should be felt in your glutes and hamstrings. Inhale as you slowly lower back down one vertebra at a time. Strong glutes are crucial for supporting your pelvis and low back.
- Perform 3 sets of 15 repetitions.
- Clamshells: Lie on your side with your knees bent and stacked, your hips stacked one on top of the other, and your head resting on your arm. Keeping your feet together and your core engaged to prevent your hips from rocking back, exhale and lift your top knee towards the ceiling. This specifically targets the gluteus medius, another key pelvic stabilizer.
- Perform 3 sets of 15 repetitions per side.
- Modified Side Plank: Lie on your side, propped up on your forearm with your elbow directly under your shoulder. Keep your knees bent and stacked. On an exhale, engage your core and lift your hips off the floor, creating a straight line from your head to your knees. Hold this position, focusing on deep, steady breathing. This exercise strengthens your obliques and TVA without putting undue pressure on the linea alba.
- Perform 3 sets, holding for 20-30 seconds per side.
Weeks 5-6: Integrating Movement & Adding Challenge
Goal: In this final phase, we begin to integrate the core strength we’ve built into more dynamic movement patterns, preparing your body for the demands of daily life and a return to more traditional fitness.
The Exercises: Perform this sequence 3-4 times per week.
- Connection Breath Warm-up: As always, start here.
- Bird-Dog: Start on all fours (quadruped position) with your hands under your shoulders and knees under your hips. Find a neutral spine. On an exhale, engage your core and pelvic floor, then slowly extend your right arm forward and your left leg straight back, keeping your hips and shoulders square to the floor. Imagine balancing a glass of water on your lower back. Inhale as you return to the start. This is a fantastic exercise for training core stability against rotation.
- Perform 3 sets of 10-12 repetitions per side.
- Dead Bug: Lie on your back with your arms extended toward the ceiling and your legs in a tabletop position (knees bent at 90 degrees over your hips). Press your low back gently into the floor. On an exhale, slowly lower your right arm and left leg toward the floor, going only as low as you can without your back arching. Inhale to return to the start. This is a step up from heel slides, further challenging your TVA.
- Perform 3 sets of 10-12 repetitions per side.
- Bodyweight Squats: Stand with your feet shoulder-width apart. Inhale as you send your hips back and down, as if sitting in a chair, keeping your chest up and your core engaged. Exhale as you press through your feet to return to standing, giving your glutes a gentle squeeze at the top. The squat is a fundamental movement pattern, and mastering it with bodyweight is key before adding external load.
- Perform 3 sets of 15 repetitions.

Beyond the Mat: A Holistic Approach to Recovery
Your comeback is more than just 20 minutes of exercise a few times a week. It’s about creating an environment that fosters healing.
- Nutrition for Healing: Your body is repairing tissues, including muscles and connective tissue like the linea alba. Prioritize protein to provide the building blocks for this repair. Incorporate sources of collagen (bone broth, slow-cooked meats) and vitamin C (citrus fruits, bell peppers), which are essential for rebuilding connective tissue.
- Gentle Movement: Walking is one of the best things you can do in the fourth trimester. It promotes circulation, which aids healing, gently engages your core, and provides a significant mental health boost. Start with short, 10-15 minute walks and gradually increase the duration as you feel able.
- Mindfulness and Grace: This is perhaps the most important element. Your body has changed, and your life has changed. Release the expectation to “bounce back.” Celebrate what your body has done. Notice the small victories—the first walk around the block, the first time you lift your baby without back pain. Give yourself the same grace and patience you so freely give to your new child.
The fourth trimester is a temporary, transformative season. By honoring your body’s need for rest and approaching your recovery with intention and gentleness, you will build a foundation of strength that will serve you for years to come — a strength that is far deeper than aesthetics. It’s the strength to lift, carry, and chase after your little one with confidence and joy.
FAQ
How can I strengthen my core after pregnancy?
You can strengthen your core after pregnancy by starting with gentle, foundational exercises that focus on reconnecting with your deep core muscles, such as diaphragmatic breathing and pelvic tilts, before gradually progressing to more challenging stability movements like bird-dogs and glute bridges.
What are the best exercises for diastasis recti?
The best exercises for healing diastasis recti are those that strengthen the deep transverse abdominis (TVA) muscle and teach proper pressure management, including connection breathing, heel slides, glute bridges, and bird-dogs, while avoiding movements that cause abdominal coning like crunches or traditional planks initially.
When can I start exercising my core postpartum?
You can begin very gentle pelvic floor and deep abdominal activation exercises, like connection breathing, within the first few days of giving birth as long as it’s comfortable, but you should wait until you are cleared by your healthcare provider (usually at 6 weeks postpartum) before starting a more structured exercise program.
How do I check for diastasis recti at home?
Lie on your back with your knees bent and feet flat on the floor. Place the fingers of one hand, palm down, on your midline at your belly button. Gently press down. Lift your head and shoulders slightly off the floor as if doing a small crunch — this will engage your rectus abdominis. Feel for the firm muscle walls on either side of your fingers. You are assessing both the width of the gap (measured in finger-widths) and the tension of the linea alba underneath your fingers. Does it feel taut like a trampoline or soft and deep like a marshmallow? The tension is actually more important than the width of the gap. If you’re unsure, a pelvic floor physical therapist can give you a proper assessment.
What are the signs I might be doing too much too soon?
Your body will give you clear signals. Be on the lookout for: any increase in postpartum bleeding (lochia) or a change in its color back to bright red; the onset of new or worsening pain in your back, hips, or pelvis; a feeling of heaviness, bulging, or pressure in your vagina, which could indicate pelvic organ prolapse; or leaking urine or feces during or after exercise. Any of these signs mean you should stop, rest, and consult with your healthcare provider or a pelvic floor PT.
Should I see a pelvic floor physical therapist?
In many countries, like France, seeing a pelvic floor physical therapist (PT) is standard postpartum care, and for good reason. I highly recommend every postpartum person have at least one consultation. A pelvic floor PT can provide a detailed internal and external assessment of your pelvic floor function and diastasis recti, and give you a personalized exercise program tailored to your specific needs and goals. They are invaluable experts in this field.
When can I return to running, lifting heavy, or high-intensity exercise?
There is no universal timeline, as every body and birth experience is different. General guidelines suggest waiting at least 12 weeks postpartum. However, before returning to high-impact activities, you should be able to perform foundational strength markers without any pain, leaking, or pelvic heaviness. This includes things like walking for 30 minutes, balancing on each leg for 10 seconds, and performing 10 single-leg bridges on each side. A slow, gradual return is always the safest bet.
My C-section incision feels sensitive. Are these exercises safe for me?
Yes, these exercises are generally safe and highly beneficial after a C-section, as they focus on the deep core muscles without putting direct strain on the superficial rectus abdominis or the incision site. However, you must wait until you are cleared by your doctor. You can also perform gentle scar massage (once the incision is fully closed and healed) to help break up scar tissue and improve mobility around the area. Always listen to your body and stop if you feel any pulling or pain at your incision site.
