Pelvic girdle pain during pregnancy: exercises that actually help

About 1 in 5 pregnant women experience pelvic girdle pain (PGP) at some point — sometimes also called symphysis pubis dysfunction (SPD). It's the sharp, deep ache where your pubic bone meets, or radiating into the back of your hips, that makes you feel like your pelvis is unzipping when you walk.

Most pregnant moms I work with have been told some version of "it's just pregnancy" — which is technically true and operationally useless. Pelvic girdle pain isn't a sign something is broken, but it absolutely responds to the right strength + movement modifications. Here's what's actually happening and what to do.

What pelvic girdle pain actually is

Your pelvis is three bones joined by three joints — the two sacroiliac joints in the back and the pubic symphysis in the front. In pregnancy, relaxin and other hormones loosen those joints so the baby can pass through during labor. That's necessary biology. The problem is when the surrounding muscles can't compensate for the looser joints, and the joints start moving unevenly under load.

The pain shows up as: stabbing in the pubic bone with single-leg movements (stairs, getting out of the car, rolling over in bed), aching in one or both SI joints, sometimes radiating down into the back of the thigh. It's usually worse with asymmetric movement — anything that loads one leg more than the other.

What's making it worse (and easy to change)

1. Asymmetric movements without bracing — getting out of the car one leg at a time, putting on pants standing on one foot, sleeping with one leg crossed over the other.
2. Wide-stance squats and lunges — anything that pulls the pelvis apart while loaded.
3. Carrying a toddler on one hip — predictably one of the worst aggravators.
4. Sitting cross-legged or in any asymmetric hip position for long periods.
5. Sleeping flat without a pillow between the knees.

What helps — the framework

Two principles cover almost everything:

1. Symmetry over range of motion. Pull your stance in. Sit with both feet flat. Get out of the car with both feet swinging together. Roll over in bed log-style (knees together, breathe out as you turn).
2. Train the stabilizers, not the movers. Glute medius (the side of your hip), deep core, and inner thighs. These hold your pelvis together. Their job is to compensate for the loose joints.

5 exercises I program for PGP clients

1. Side-lying clamshells

Lie on your side, knees bent at 45°, heels stacked. Keeping your heels together, lift the top knee toward the ceiling without rolling your hips back. Slow. 12–15 reps each side, daily. This is the cleanest glute med activation that doesn't load the pelvis asymmetrically.

2. Bodyweight glute bridges with feet narrow

Feet hip-width or narrower (not wider), knees pointing forward. Press through your heels, drive your hips up, squeeze your glutes at the top. Avoid pushing through your low back. 10–15 reps, 2–3 sets. Narrow stance = less pelvic spread.

3. Tall-kneeling band pulls / chops

Up on your knees, knees hip-width, band anchored at chest height. Pull the band across your body diagonally. This trains your obliques and deep core to stabilize your pelvis under rotational load — without standing.

4. Heel slides on your back

Lie on your back (only in the first half of pregnancy, or with the upper body propped after 20 weeks), one knee bent foot flat. Slide the bent leg's heel away from you slowly without letting your low back arch. 10 each side. Re-coordinates the deep core / pelvic floor / inner thigh under low load.

5. Wall sits (modified hold)

Back against a wall, feet hip-width, slide down only as far as feels good (often a partial range). Hold for 15–30 seconds. Squeeze a small pillow or yoga block between your knees. Both legs work equally, the pelvis stays neutral, glutes wake up.

What to avoid in the meantime

• ✓Wide-stance squats, sumo deadlifts, side-lunges
• ✓Single-leg loaded work (Bulgarian split squats, pistol squats, single-leg deadlifts) until symptoms resolve
• ✓Long walks on uneven ground (treadmill is often better)
• ✓Yoga poses that open the hips aggressively (pigeon, deep warrior 2, wide-leg forward fold)
• ✓Carrying older kids on one hip — switch sides constantly or use a structured carrier centered on your body

When to see a pelvic floor PT

If PGP is severe enough that single-leg activity (stairs, getting out of the car, rolling in bed) is producing tears, or if it's not responding to symmetric strength work after 2-3 weeks, see a pelvic floor PT. Lehigh Valley has several excellent ones — I refer specifically based on which symptom is dominant.

PFPTs do internal pelvic floor work plus hands-on SI joint mobility that a trainer cannot legally or ethically do. The combination — PFPT work + NASM-credentialed prenatal strength training — resolves the vast majority of PGP cases by the third trimester.

If you're in the Lehigh Valley

Prenatal in-home 1-on-1 training across Saucon Valley, Center Valley, Coopersburg, Lower Macungie, and the surrounding affluent neighborhoods means someone with NASM Pre/Postnatal Performance Specialization comes to your home, watches you move, and programs around your specific PGP pattern. No driving to a gym at 32 weeks pregnant with a toddler in the back seat.

FAQs

Will pelvic girdle pain go away after I deliver?

For most people, yes — the hormone surge ends, the joints firm back up, and pain resolves over 2–6 months postpartum. But postpartum PGP that lingers past 3 months should absolutely be seen by a pelvic floor PT. It's not normal to live with it forever.

Is it safe to lift weights with PGP?

Yes — with modifications. Symmetric loading (both legs working equally), narrow stances, no single-leg loaded work, no wide-stance moves. A NASM-certified prenatal trainer should be programming around your symptoms, not asking you to push through them.

Can I still walk for cardio?

On flat ground, in supportive shoes, for the distance that doesn't reproduce symptoms — yes. Many PGP clients tolerate treadmill better than outdoor walking because the ground is even. Pool walking is excellent if you have access.

Should I wear a pregnancy belt?

A supportive pregnancy belt (SI Loc, Serola, or a maternity-specific belt) can dramatically reduce symptoms during activity. Use it for symptomatic days, not constantly — the belt is a tool, not a replacement for strength work.
