Common Postpartum Behaviors That Damage Pelvic Floor Muscles and Contribute To a Weak Pelvic Floor After Childbirth

Many everyday behaviors unknowingly damage your recovery after delivery. The most common habits that contribute to a weak pelvic floor after childbirth include chronic straining during bowel movements, improper breathing during heavy lifting, and rushing back to high-impact exercises like running. Inside the body, 

High-impact habits exert downward pressure on recovering muscles, which directly stalls postpartum healing. Addressing these physical patterns is essential to prevent long-term pelvic floor dysfunction.

Daily Postpartum Behaviors That Damage Pelvic Floor Muscles

Postpartum individuals frequently strain pelvic floor muscles by maintaining improper alignment and pressure management during daily routines. Modifying these specific daily postpartum behaviors that damage pelvic floor muscles accelerates tissue rehabilitation and restores core stability.

1. Crossing Your Legs Constantly

Sitting with your legs crossed shortens the muscles of the pelvic floor and hips. Over time, this creates tension and imbalance that can lead to pain or leakage. Try sitting with both feet flat on the ground and your hips supported instead.

2. "Just in Case" Bathroom Habits and Bladder Confusion

New moms often go to the bathroom before leaving the house or feeding the baby “just in case.” The problem? This trains your bladder to signal the urge too frequently. Ideally, you should urinate every two to four hours — not every 30 minutes. Retraining these signals helps restore normal bladder-brain communication.

3. Ignoring the Urge to Go

On the flip side, holding your bladder for long stretches (common for teachers, nurses, and busy parents) can overstretch the bladder and desensitize those same signals, leading to leakage later on.

4. Incorrect Heavy Lifting and Improper Breathing

Whether you’re at the gym or lifting your baby’s car seat, holding your breath (the Valsalva maneuver) increases pressure on the pelvic floor. Instead, exhale as you lift — a small change that protects those recovering muscles.

5. Slouching and Poor Posture Imbalances

Slouching with your tailbone tucked under shortens and tightens the pelvic floor. Sitting tall with a slight natural curve in your lower back helps relieve tension and keeps the muscles balanced.

6. Chronic Straining and Constipation

Ignoring bowel urges or pushing too hard strains the pelvic floor. Gentle breathing, proper hydration, and consistent toilet habits can make a big difference.

7. Premature High-Impact Exercise

Jumping back into high-impact workouts too quickly can cause downward pressure that the pelvic floor isn’t ready for. Always get clearance from your provider and start with gentle, restorative movements.

Why the Postpartum Pelvic Floor is Vulnerable to Injury

Understanding why the postpartum pelvic floor is vulnerable helps mothers safely navigate their recovery timelines. During pregnancy, elevated levels of the hormone relaxin loosen ligaments while the weight of the baby continuously stretches the deep core stabilizers. 

Ultimately, Pregnancy hormones weaken pelvic tissues, meaning that even a cesarean delivery requires a dedicated period of intentional, low-impact healing.

Because your pelvic floor muscles are so uniquely vulnerable after childbirth, rebuilding awareness and control is essential. If you are struggling with a weak pelvic floor after childbirth, simple lifestyle shifts are your first line of defense. 

At Mendwell Health, we help you replace these unhelpful everyday habits with proper breathing techniques, intentional posture, and gradual, safe strengthening under the guidance of a pelvic floor physical therapist.
