How to Return to Exercise After Having a Baby

Your six-week OB appointment goes well. Your doctor says you're cleared to exercise. You lace up your shoes, head out for a run, and feel like something is deeply wrong. Pressure. Heaviness. Leaking. You're confused because you were cleared.

Here's what most postpartum women aren't told: that clearance is for wound healing and general physical recovery. It's not a biomechanical assessment of your pelvic floor, core, and connective tissue. It's not a green light for running, jumping, or loading your spine with weights. Your body needs more than six weeks — and the path back is more specific than most women realize.

Check for diastasis recti first

Before any core work, you need to know whether you have diastasis recti — the separation of the two halves of the rectus abdominis muscle that occurs during pregnancy. About 60% of women have some degree of it at six weeks postpartum.

Here's how to check yourself:

Lie on your back with knees bent. Place two fingers horizontally across your midline, just above your belly button. Slowly lift just your head and shoulders off the floor — not a full crunch. Press your fingers down gently and feel how wide the gap is and whether the tissue holds tension.

A gap of more than two finger-widths, or tissue that feels soft and unsupported like you could sink your fingers in, suggests meaningful diastasis. That's not a reason to avoid exercise — but it does mean avoiding exercises that push intra-abdominal pressure outward, like traditional crunches, sit-ups, and double-leg lowering.

"Many women are doing exercises postpartum that are actively working against their recovery," says Dr. Sara Reardon, DPT, pelvic floor physical therapist and founder of The Vagina Whisperer. "A pelvic floor PT can identify dysfunction that no one else is checking for and give you a program that actually matches where your body is."

If you have any concerns after the self-test, book a pelvic floor physical therapy appointment before progressing your training. It's the single best investment you can make in your postpartum recovery.

Phase 1: Weeks 1-6 — Foundation work

Your goal in these weeks is reconnecting with your deep core and pelvic floor, not building fitness. You're not deconditioned. You're healing.

Diaphragmatic breathing

This is the starting point for everything. Lie on your back, knees bent. Breathe in through your nose and let your belly expand in all directions — front, sides, and back. On the exhale, feel your pelvic floor gently lift and your deep abs draw inward. This isn't a forced kegel. It's the natural response to a complete exhale.

Practice 10 breaths, 2-3 times a day. It sounds minimal because it is. This is still where you start.

Pelvic floor activation

With the breathing pattern established, add a gentle pelvic floor contraction — a Kegel — during your exhale. Hold for 5-10 seconds. Release fully and let the muscles relax completely. That release matters as much as the contraction.

Walking

Walking is your primary cardiovascular exercise in Phase 1. Start with 10-15 minutes and gradually build to 30 minutes by week six. Go at a pace that feels comfortable, and stop if you feel any downward pressure, heaviness, or leaking.

What to avoid entirely: running, jumping, heavy lifting, traditional abdominal exercises, and any movement that causes symptoms.

Phase 2: Weeks 6-12 — Rebuilding foundations

You have your six-week clearance. Your healing is complete. Now you rebuild — but still with bodyweight and light loads. This is not the time to return to your pre-pregnancy training intensity.

Glute bridges

Lie on your back, knees bent, feet flat. Drive through your heels to lift your hips until your body forms a straight line from shoulders to knees. Squeeze your glutes at the top. Lower slowly. 3 sets of 12-15.

Exhale as you lift. Inhale as you lower. Keep that breath-core connection you built in Phase 1.

Bodyweight squats

Feet hip-width apart, toes turned out slightly. Sit back and down, keeping your chest tall. Drive through your heels to stand. 3 sets of 10-15. Focus on control, not speed.

Bird dogs

On hands and knees, brace your core gently. Extend your right arm and left leg simultaneously, keeping your hips level. Hold 2-3 seconds. Return and switch sides. 3 sets of 8 per side.

This exercise builds deep core stability and trains your body to resist rotation — both critical for postpartum recovery.

Heel slides

Lying on your back, knees bent. Engage your deep core and slowly slide one heel out until the leg is almost straight. Slide it back. Alternate legs. 3 sets of 10 per side. Stop if you feel your lower back arch away from the floor.

Skip entirely in Phase 2: crunches, sit-ups, double-leg lowering, any jumping or impact, heavy loaded exercises.

Phase 3: 3+ months — Progressive return to full training

At three months, if you're symptom-free, you can begin returning to more challenging training. Progressive loading, compound lifts, and eventually impact activities all come back — but sequentially, not all at once.

Start with loaded versions of Phase 2 exercises. Add weight to your squat and hip thrust. Introduce Romanian deadlifts. Progress to split squats and step-ups. Build a 4-6 week foundation of weighted training before adding impact.

"I tell my patients that running is an advanced exercise for the pelvic floor," says Dr. Reardon. "It generates ground reaction forces 2.5 times your body weight through the pelvic floor with every stride. The floor needs to be ready for that."

Running is typically safe between three and six months postpartum, when pelvic floor function has been assessed (ideally by a PT) and you've been symptom-free for several weeks. A clearance milestone often used by pelvic floor PTs: you can walk briskly for 30 minutes, complete 20 consecutive single-leg calf raises, and perform 10 single-leg squats with control and no symptoms.

Warning signs that mean stop

These symptoms during or after exercise are signals your body is telling you to back off — not push through:

• Pressure, heaviness, or bulging in the pelvic region
• Urinary or fecal leaking
• Pain in your abdomen, pelvic floor, hips, or lower back
• Your midsection doming or coning during exercises
• Symptoms that persist hours after training ends

Any of these warrant a step back in your training and a conversation with a pelvic floor PT before continuing.

The timeline in realistic terms

Weeks 1-6: Breathe, walk, rest. Let your body heal. This is not wasted time.

Weeks 6-12: Bodyweight movements with full attention to pelvic floor response. Build the foundation.

Month 3-4: Begin progressive loading. Compound lifts return. Still no running.

Month 4-6: With pelvic floor clearance and symptom-free training, impact activities can return — including running.

Month 6+: Back to full training with appropriate load progression.

Your pre-pregnancy fitness will come back. It takes longer than six weeks. It takes longer than three months in many cases. But women who take this progression seriously come back stronger and with significantly less chronic injury than those who rushed it. Your body earned careful handling.
