How to relax your pelvic floor to poop: a step-by-step guide

To open your bowels, the pelvic floor and the ring of muscle around the back passage have to relax and drop while your belly gives a gentle push. If they tighten instead, you strain and little comes. The fix is a few things done together: knees above hips on a footstool, lean forward, belly breathing, and a soft, long breath out (a "moo" or a sigh) instead of holding your breath and pushing hard.

Doctors call the tightening-instead-of-relaxing pattern dyssynergic defecation, a common cause of long-term constipation, and it responds well to retraining. This guide gives the steps on the toilet, a daily practice to teach the let-go, and the signs that need a doctor.

Why the pelvic floor matters for pooping

The pelvic floor isn't only for holding in urine. One of its muscles, the puborectalis, loops around the back of the rectum like a sling and pulls it forward, which keeps a bend in the bowel so stool stays in. To poop, that sling has to relax so the bend straightens, and the anal sphincters have to open. At the same time the belly muscles push gently down.

If the floor tightens when you push (often without you knowing), it's like pushing toothpaste against a closed cap. Women with a tight pelvic floor, a history of holding in, pain, stress, or years of strong Kegels without the let-go are more likely to do this. See tight pelvic floor symptoms for the wider signs.

Signs your pelvic floor isn't letting go

• You strain hard even when the stool is soft.
• You feel stool "right there" but it won't come out, or feel blocked at the outlet.
• You feel you haven't finished, and go back several times.
• You need to press around the back passage or in the vagina to get stool out (called splinting).
• You spend more than 10 minutes on the toilet most times.
• You also have trouble starting to pee, pelvic pain or pain with sex.

Slow bowels (the stool moves slowly through the gut) feel different: few urges, hard pellets, and bloating. Many women have a bit of both. A doctor can tell them apart with simple tests (below).

How to relax your pelvic floor on the toilet: step by step

1. Go when you feel the urge. The urge is strongest 15 to 45 minutes after a meal, especially breakfast, and a warm drink helps. Waiting makes the stool drier and the urge fade.
2. Sit all the way down. No hovering.
3. Feet on a stool, about 6 to 9 inches high, so your knees are higher than your hips. Spread your knees a little apart.
4. Lean forward, with a straight back and your forearms on your thighs. This straightens the bend at the bottom of the bowel.
5. Let your belly go soft. Breathe in slowly through your nose and let your belly expand out to the sides and front. Feel the floor drop as you breathe in.
6. Widen your waist. Make your belly firm and round, as if you were pushing it out into a belt, not sucking in. Doctors sometimes call this "big belly, hard belly."
7. Breathe out slowly with your mouth open, making a low "moo," "shhh" or a long sigh. Keep the belly wide as you do. This gently pushes down without clamping the outlet. Don't hold your breath and bear down hard.
8. Think "open" and "drop." Picture the back passage softening and opening, like a flower opening or a lift going down one floor. Unclench your jaw and your buttocks: they're linked to the floor.
9. Repeat a few breaths. If nothing comes after about 5 minutes, get up and try later. Long sits and hard straining add to hemorrhoids and strain the floor.
10. When you're done, stand up and draw the floor gently up for a second to finish, then let go.

Practice the let-go off the toilet

It's hard to learn a new pattern while straining. Practise when you're not trying to go, 5 to 10 minutes once or twice a day, lying down first.

1. Belly breathing (2 to 3 minutes)

Lie on your back, knees bent, one hand on your belly and one on your chest. Breathe in through your nose so the lower hand rises and the chest stays still; feel the floor soften and drop between your sit bones. Breathe out slowly through your mouth and let it return on its own. Our guide to how to relax your pelvic floor muscles has the full breathing routine.

2. The drop (2 minutes)

As you breathe in, gently let the area around the back passage soften and bulge a little outward, as if starting to pass wind, without pushing hard. Hold the soft feeling for 3 to 5 seconds, then rest. Do 8 to 10. This is the reverse Kegel; reverse Kegels for women shows how to tell a release from a push.

3. Squeeze and let go (1 minute)

Squeeze the back passage gently, then let it go fully, then let it go a little more. Feeling the difference teaches you what "relaxed" is.

4. Two stretches (2 to 3 minutes)

• Happy baby: lying on your back, hold the outsides of your feet with knees wide; breathe into your belly for 60 to 90 seconds.
• Child's pose with knees wide: kneel, sit back toward your heels, arms forward, and breathe into your lower back and floor for 60 to 90 seconds.

5. Practise on the toilet

After a week or two, sit on the toilet with the stool under your feet, lean forward and do the breathing and the "moo" breath, even with no urge, so your body learns the position.

Help the stool too

Relaxing the floor works best when the stool is soft and formed (types 3 to 4 on the Bristol stool chart: like a sausage, smooth or with cracks).

• Fibre: most US women eat less than the 22 to 25 grams a day the Dietary Guidelines advise for adult women. Add slowly over 2 weeks (oats, beans, lentils, fruit, vegetables, wholegrains, ground flaxseed) to avoid bloating. Psyllium is a well-studied supplement.
• Fluids: enough that your urine is pale, spread through the day.
• Kiwifruit and prunes: two green kiwis a day or a handful of prunes helped in trials for constipation.
• Move: a daily walk helps the gut move.
• A regular time: sit after breakfast each day for a few minutes, even without a strong urge.
• Gentle belly massage: lying down, with a flat hand, circle slowly clockwise around the belly button (up the right side, across, down the left), 5 to 10 minutes.

Laxatives can help in the short term; ask a pharmacist or doctor which suits you, especially if you take other medicines.

Why it gets harder after 40

• Menopause: lower estrogen affects the pelvic tissues and gut, and many women notice more constipation in the transition. See menopause bladder and bowel problems.
• Prolapse: a rectocele (the back wall of the vagina bulging) can trap stool, so it feels blocked; pressing on the back wall of the vagina to get it out is a common sign. Tell a doctor.
• Medicines: iron, some pain medicines (especially opioids), some antidepressants, calcium and some blood pressure medicines can constipate.
• Years of habits: holding in at work, rushing, straining and strong Kegels without the let-go all teach the floor to stay tight.

Mistakes that keep you straining

• Pushing harder. More force usually means more clamping. Softer, longer breaths out work better.
• Holding your breath. It braces the whole trunk, floor included.
• Ignoring urges. The rectum adapts and the urge fades, and the stool gets drier.
• Sitting for a long time. It strains the floor and blood vessels without helping.
• Doing lots of Kegels to "fix" constipation. If your floor is tight, more squeezes make it worse. See can you do too many Kegels.

When to see a doctor

• Soon: blood in your stool or black stools, a change in bowel habit lasting more than 3 weeks, weight loss you can't explain, a family history of bowel cancer, or new constipation after 50.
• Urgently: severe belly pain, a swollen belly with vomiting, or no stool or wind at all.
• When self-help isn't enough: straining, blockage or splinting that continues after 4 to 6 weeks of the steps above, or a bulge in the vagina.

What a doctor may do

Besides an exam, a doctor may refer you for an anorectal manometry test (a small probe measures whether the muscles relax when you push) and a balloon expulsion test. If the floor tightens when it should relax, biofeedback therapy with a pelvic floor physical therapist is the recommended treatment in the American College of Gastroenterology and American Gastroenterological Association guidance; in trials it helped most people with this pattern, more than laxatives alone. Sessions use a sensor and a screen so you can see the muscles relax.

Frequently asked questions

Why does my pelvic floor tighten when I try to poop?

It's a learned pattern, often from holding in, pain, stress or straining. The muscle braces instead of letting go. Practice off the toilet and biofeedback retrain it.

Does a squatty potty really help?

Raising the knees above the hips helps many people strain less, though not everyone. A pile of books or any low step works the same.

Why does rocking back and forth help me poop?

Rocking shifts the pelvis and can help the floor relax and the rectum line up. If you need it every time, the floor may not be letting go well.

Can a tight pelvic floor cause constipation?

Yes. If the outlet muscles don't relax, stool is hard to pass even when it's soft.

How long does it take to retrain the pelvic floor for bowel movements?

Many people notice a change in 2 to 6 weeks of daily practice; biofeedback programmes typically run about 4 to 6 sessions.

Should I do Kegels for constipation?

Not if the floor is tight. Learn the let-go first; strength work comes later, if a therapist says you need it.

Where to start today

Put a stool by the toilet, and next time try lean forward, belly wide, long "moo" breath out, for no more than 5 minutes. Practise belly breathing and the drop for 5 minutes tonight.
