Pilates guide
Pilates can help your digestion in ordinary ways: moving your body helps your bowels and helps gas move on, staying upright after meals helps reflux and fullness, and breathing into your ribs may ease a swollen, uncomfortable tummy. What it doesn't do is massage or detox your organs, and only one small trial has tested Pilates for a gut problem. Walking has more evidence for constipation, so Pilates works best as one part of being active.
This guide covers what happens in the gut when you move, what the evidence shows for constipation, bloating, IBS (irritable bowel syndrome) and reflux, breathing for a swollen tummy, letting the pelvic floor go and how to sit on the toilet, timing Pilates around meals, the moves to do and skip, the routines to follow, and the warning signs that need a GP. Our Pilates for bloating, Pilates for IBS and Pilates for acid reflux guides go deeper into each.
The NHS says "A daily walk or run can help you poo more regularly." and suggests you "exercise regularly to improve your digestion and help prevent bloating". No study has shown that Pilates itself speeds digestion; walking and being active overall have more evidence than any particular move.
Searches on 3 November 2026 found one published Pilates trial in a gut condition: in 60 Egyptian women with constipation-type IBS, adding 16 Pilates sessions to diet advice eased symptoms more than diet advice alone. It was unblinded, with no comparison exercise. Nothing has tested Pilates for constipation alone, bloating or reflux.
In 9 small trials, mostly of walking and qigong, more people improved with exercise, though the trials were at high risk of bias. Thirty minutes of brisk walking a day sped up the gut in 43 people with constipation. In care homes, 6 months of strength and skills training didn't change constipation.
In 94 adults with bloating, a 10 to 15-minute walk after each meal for 4 weeks eased fullness and bloating after meals more than medicines did. Staying upright and moving helps gas move on; lying on your back slows it.
Scans show the tummy contents barely increase: the diaphragm pushes down and the tummy wall relaxes. Retraining the breath and tummy wall with specialist biofeedback cut visible swelling by 56% and 66% in two placebo-controlled trials. Pilates rib breathing points the same way, but hasn't been tested.
If you strain and can't empty, the pelvic floor may tighten when it should relax: learn to let it go, and see a GP, because specialist biofeedback is the tested treatment. Blood in your poo, a change in your bowel habit, losing weight without trying or a lump in your tummy need a GP, and Pilates never stands in for that.
Bowels are an ordinary part of health, and doctors are used to talking about them.
The bowel's own muscle moves food along, and exercise speeds this up in some studies but not others. Constipation has many causes: the NHS lists "not eating enough fibre", "not drinking enough fluids" and "not moving enough and spending long periods sitting or lying down" among the most common. In older people, constipation "may be easily missed".
About 18% of people feel bloated at least once a week, and women about twice as often as men. Passing wind is normal: the NHS says "Farting, also known as flatulence or wind, is normal." Being upright and moving lightly helps gas pass; lying on your back slows it.
During a bad swelling, the tummy contents rise by only about 0.3 litres. Instead, as Guts UK explains, "The diaphragm contracts (shortens) and the belly wall muscles relax. This causes the guts contents to be pushed downwards and the belly to bulge outwards." Muscle recordings show the tummy wall failing to tighten slightly as it normally would. This is a reflex, not weak abs.
The pelvic floor has to relax to let poo out. In some people it tightens instead, which causes straining and a feeling of not having emptied fully. Lying down makes emptying much harder than sitting.
The diaphragm wraps around the bottom of the gullet. Breathing training can strengthen that barrier a little, while bearing down (holding your breath and pushing) brings on reflux. Our Pilates for acid reflux guide covers reflux in depth.
IBS and anxiety often go together. The NHS suggests plenty of exercise and ways to relax for IBS, and NICE (the National Institute for Health and Care Excellence) asks GPs to encourage people with IBS "to create relaxation time". The calm of a class may help how you feel, though slow breathing alone didn't change IBS symptoms in a small pilot.
Lying flat and curling up (the Hundred, roll-ups, the roll-over) can bring on reflux or discomfort soon after a meal, and roll-ups kept tummy pressure higher for longer than other moves. Lying face down can be uncomfortable on a swollen day. Pilates breathing, into the sides of the ribs with the lower tummy gently in, is close in direction to the retraining used for a swollen tummy, and the opposite of pushing the belly out, which made bloating feel worse after a big meal.
Most studies here are small, and many are lab studies of a few people. Diet, medicines and talking therapies carry more evidence for IBS than exercise does.
Sixty women aged 20 to 45 with overweight and constipation-type IBS all got diet advice; half also did 16 supervised mat and ball sessions over 8 weeks. Symptom scores after treatment were about 104 against 175 on a 500-point scale, and bowel movements rose more. But the person scoring the results knew who had done Pilates, the other group got no extra attention, there was no follow-up and harms weren't reported. A standing Pilates trial in 33 adults with reflux finished in 2025 with no results posted.
A 2026 network analysis ranked Pilates second for IBS symptoms, but its Pilates result is that one trial, and some of its figures are printed back to front. One trial can't show that Pilates beats other exercise.
In Cochrane's review (11 trials, 622 people), being more active improved IBS symptoms by about 69 points on a 500-point scale, where 50 is a meaningful change, but "the evidence is very uncertain", with no clear effect on quality of life or pain. In the largest trial, 102 people helped to be more active for 12 weeks improved by 51 points against 5. UK gut specialists say people with IBS "should be encouraged to increase physical activity, where feasible". Yoga hasn't beaten control groups in 11 trials (535 people).
In 9 trials (680 people, mostly walking and qigong), exercise roughly doubled the chance of improving, but the trials were at high risk of bias. In 13 studies following 119,426 people, the most active were less often constipated, though in a large US survey the link faded once fibre, fluids and health were taken into account.
An hour of jogging or cycling a day sped food through the gut in 10 healthy people, without more frequent poos. Thirty minutes of brisk walking a day for 12 weeks cut colon transit from about 79 to 58 hours in 43 adults with constipation, and 2 weeks of rest slowed it in 9 active older men. But getting fitter over 7 to 9 weeks (14 people) and a week of walking (16 men) made no consistent difference.
Twelve weeks of crunches and planks made young women's tummy muscles stronger without speeding gut transit compared with not training. No study has tested twists, or any single Pilates or yoga move, for gut function or "detox"; a 2025 review that repeats the twist claim cites a 1991 yoga study in which "none of the patients improved clinically". Most beginner Pilates moves press on the tummy no harder than standing up from a chair.
In 8 healthy people, sitting upright cleared gas faster than lying on the back (13 mL left behind against 146 mL). In 8 people with bloating, light pedalling cut the gas held back from 45% to 24% and eased symptoms. A 10 to 15-minute walk after each meal for 4 weeks eased fullness and bloating more than two medicines in 94 adults, in an unblinded trial.
The 2025 European consensus says physical activity "seems to have a positive impact" on gut symptoms including bloating, but adds that no pooled analysis or randomised trial has shown that exercise treats bloating on its own.

Diaphragmatic breathing training eased reflux symptoms in 10 small trials (476 people), without a clear change in quality of life. Diaphragmatic breathing after meals cut reflux, and bearing down brought it on in most people with reflux. Belching halved in 9 of 15 people who trained their breathing, against none of 21 who didn't. UK gut specialists strongly recommend regular aerobic exercise for indigestion, on very low quality evidence.
Aim for about 30 minutes of brisk walking a day, the dose that sped up the gut in a trial, or a 10 to 15-minute walk after meals. Guts UK says keeping active may help a sluggish bowel. Pilates is part of being active, not a laxative.
Eating enough fibre and drinking enough fluid are on the NHS's list of first steps, alongside moving more. Give yourself time on the toilet without rushing.

The NHS suggests resting your feet on a low stool so your knees are above your hips. A squat-like position cut straining in 28 healthy people and a posture stool helped 52 healthy people empty, but a stool didn't help simulated emptying in 41 people with constipation. US gut specialists say a footstool "has little if any risk, although studies are needed to evaluate this technique".
If you strain because the pelvic floor tightens instead of relaxing, specialist biofeedback helped 80% against 22% with laxatives at 6 months (109 people), and a 2026 review of 19 trials rated the benefit moderate certainty. US guidelines say general pelvic floor exercise without feedback "is not effective" for this. In England, specialist habit training (posture, breathing and routine) did as well as adding biofeedback. Pilates teaches drawing the pelvic floor up; practise letting it go too, never push down, and see a GP if straining goes on.
Constipation is common later in life. Strength training alone didn't help it in care homes, while bowel training with a better toilet position helped people with dementia, and yoga 3 times a week improved constipation-related quality of life in 96 adults aged 60 to 75 in a weak trial.
Massaging your tummy by hand added about 1.6 bowel movements a week in pooled trials (23 studies, 1,431 adults), as "a complement to laxatives rather than a substitute", and the largest UK trial (189 people with multiple sclerosis) narrowly missed its main result. Pilates moves are not massage; our exercise for constipation guide covers it.
Muscle-recording biofeedback over 3 sessions cut visible swelling by 56% against 13% with a placebo (48 people), and belt-guided biofeedback with home practice 3 times a day by 66% (42 people), both from one research group in Barcelona. The European consensus accepts it on very low evidence, with home practice "for 5 min before and after breakfast, lunch, and dinner", and says a version without equipment "is still under development". This needs a specialist; it isn't a Pilates class.
The retraining relaxes the diaphragm with the "chest up" and the "abdomen in". In 16 healthy women after a big meal, pushing the belly out made bloating feel worse than relaxing it. Written breathing instructions practised at home eased bloating in a trial with no untreated group. Pilates lateral breathing is similar in direction; that it helps is our inference, untested.
In 156 people with severe bloating not helped by diet, 64% of those tested couldn't push out a test balloon normally, and pelvic floor biofeedback helped about half. Guts UK says "Pelvic floor biofeedback treatment can cut bloating and distension symptoms in half."
These are the steps from our Pilates for bloating guide. Our suggestion, untested: they borrow the "chest up, abdomen in" pattern taught in the biofeedback trials, which used specialist equipment (Melchior 2025; Barba 2017 and 2024), and the 5 minutes follows the home practice in the European consensus. No study has tested Pilates breathing for the gut.

Guts UK says heartburn "usually occurs after eating, lying down, or bending over", and the NHS bloating page says not to "slouch when eating". After a light meal, standing and sitting moves are fine. Leave lying flat, curling and head-down moves for about 2 hours after a big meal, especially with reflux, as our Pilates for acid reflux guide explains.
A 10 to 15-minute walk after each meal eased fullness and bloating in a 4-week trial. A short walk after eating, and Pilates once your meal has settled, is our suggestion.

Bearing down brought on reflux in a lab study. Keep breathing through every move, and on the toilet.

A walk (10 to 15 min, our morning routine for constipation and the after-meal trial's dose) or a standing march (2 minutes, our bloating class), then thoracic rotation (6 each side, our bloating and acid reflux classes) and the breath reach (5 breaths, our bloating class).
Lateral breathing, 5 to 8 breaths at the start of every session (from the move page's dose), then about 5 minutes on a bloated day (the steps above, our suggestion); slow breathing, 1 minute (our bloating class) or 2 minutes (our acid reflux class), with no holds, for the stress side of IBS.
Cat-cow (8 slow waves), the bird dog (5 each side), the mermaid (3 each side, sitting tall), the clamshell (10 each side) and the side kick (8 each side), all from our bloating class; the side-lying open book (5 each side, our pelvic floor class), a gentle twist with no pressure on the tummy.
Pelvic tilts then bridges (8 tilts, then 6 bridges), the knee fold (6 each side), a single knee hug (2 holds of 20 seconds each side) and the lying twist (3 slow breaths each side), all from our bloating class; the double knee hug (3 holds of 20 to 30 s, our morning routine for constipation), which you should skip with osteoporosis, as its caution says. No study has tested any of these for the gut.
Pelvic floor relaxation, 5 to 10 slow breaths, 1 to 3 times a day (from the move page's dose). Its caution says "Never push down or strain."
No lying flat, head-down or curling moves; use upright moves only, as our Pilates for acid reflux guide explains. With a hiatus hernia, that guide applies too.
Skip long curls and roll-ups (the roll-up and the Hundred), face-down moves (the swan and swimming), and rolling or legs-overhead moves (rolling like a ball, the roll-over and the jack knife), as our Pilates for bloating guide advises. Roll-ups kept tummy pressure high for longest in a lab study. These are comfort changes, not bans.

Practise letting the pelvic floor go, never push down, and see a GP if straining goes on: specialist biofeedback is the tested treatment.
Leave it out: it has no gut evidence, and breathing should stay soft and slow.
Follow your team's advice and the swaps in our Pilates for hernia, exercise with a stoma and Pilates for Crohn's disease guides.
Skip the double knee hug and deep curls, and use the swaps in our Pilates for osteoporosis guide.
There is no new digestion class on purpose: walking and being active help most, and these cover the rest. The 20-minute bloating class is the closest Pilates class; the morning routine is a walk, knee hugs and letting go; the walk and Pilates workout puts a brisk walk first (skip its Hundred and single-leg stretch on a bloated day); the upright acid reflux class suits after a meal; and the Crohn's and colitis class is for remission days.

This is general information, not a diagnosis. A&E means accident and emergency; in the US, call 911 for 999, and use your doctor's urgent line or urgent care for NHS 111.
The NHS says call 999 or go to accident and emergency (A&E) if you have severe tummy pain with vomiting or a swollen tummy, or bleeding from your bottom that won't stop, or a lot of blood or large clots when you poo.
It also says call 999 or go to A&E now if you have a stomach ache and:
If you have bloating with a swollen stomach and a stomach ache that is severe and came on very suddenly, you're vomiting blood or your vomit looks like ground coffee, or you have severe difficulty breathing. Don't drive yourself to A&E. During exercise, stop and get help for chest pain or pressure, unusual breathlessness, dizziness or fainting, as our plans advise.

Call 999 if:
Call 999 or go to A&E (accident and emergency) straight away for severe difficulty breathing (gasping, choking or not able to get words out), a chest that feels tight or heavy, pain that spreads to your arms, back, neck and jaw, lips or skin turning very pale, blue or grey, or sudden confusion. If you're more short of breath than usual, or your heart is racing, fluttering or skipping beats, contact NHS 111.
Source 69
If you have bloating with being sick, diarrhoea or constipation, or with a stomach ache; a high temperature, or you feel hot, cold or shivery; a swelling or lump in your tummy; a burning feeling in your chest caused by stomach acid travelling up towards your throat (acid reflux); or you can't pee, poo or fart. In the US, contact your doctor or urgent care.

The NHS says these could be signs of something more serious:
The NHS says see a GP if you have any symptoms of bowel cancer, such as changes in your poo, blood in your poo, which may look red or black, tummy pain, a lump in your tummy or losing weight without trying. The NHS adds: try not to be embarrassed, because doctors are used to talking about these symptoms.
If you feel bloated regularly, or have bloating with weight loss you can't explain or blood in your poo: the NHS says bloating that doesn't go away can sometimes be a sign of something more serious, such as ovarian cancer, whose symptoms include a swollen tummy or feeling bloated roughly 12 or more times a month.
The NHS lists "swelling in your feet, ankles, legs or tummy, or feeling bloated" among the symptoms of heart failure. If you have heart failure and your tummy is newly swollen, with swollen ankles, more breathlessness or sudden weight gain, contact your heart failure team, as our Pilates for heart failure guide explains (our suggestion).

You feel any pain or become unwell, as the NHS advises for its Pilates videos, and especially for chest pain or pressure, unusual breathlessness, dizziness or fainting. If you have a health problem, an injury or any symptoms, get advice from a healthcare professional, such as a GP, before you start.

Untested. No study has tested twists, or any single Pilates or yoga move, for gut function or detox, and the 1991 yoga study a recent review leans on found that none of its patients improved clinically. Twists are fine to do if they feel good.
Not shown. Twelve weeks of crunches and planks strengthened young women's trunks without speeding gut transit, and most beginner Pilates moves press on the tummy no harder than standing up from a chair. Tummy massage by hand is a different thing, with small trials behind it as an add-on.
Not as claimed. A visibly swollen tummy is mostly the diaphragm pushing down and the tummy wall relaxing, with little extra gas, and it eased with breath and tummy-wall retraining, not with strengthening. Bloating isn't a sign of weak abs.
Partly. Exercise sped the gut along in some studies, though one found faster transit without more frequent poos, and walking has more evidence than Pilates for constipation. Needing the toilet during or after a class is normal; a change in your bowel habit that lasts weeks needs a GP.
Not for gas or reflux. Lying on your back slows gas through the gut, a short walk after meals eased fullness and bloating, and heartburn often comes after eating, lying down or bending over.
Not after a big meal: pushing the belly out made bloating feel worse in 16 women. The tested retraining relaxes the diaphragm with the chest up and the tummy gently in.
No study has tested it. Slouching while you eat is on the NHS's list of things to avoid for bloating, which is a reason to sit up at meals, not proof of harm to your organs.

No. One small trial in women with constipation-type IBS, and being active helps IBS a little at very low certainty. Diet, medicines and talking therapies carry more evidence, as our exercise for IBS guide explains.
It can help as part of being active, which the NHS says helps you poo more regularly and helps prevent bloating. But only one small trial has tested Pilates for a gut problem (constipation-type IBS), and walking has more evidence for constipation.
Possibly, as one way to move more, but it hasn't been tested on its own. Brisk walking for 30 minutes a day sped up the gut in people with constipation, so walk most days and use Pilates alongside.
Some people need the toilet during or after exercise, and moving speeds the gut along in some studies, though not always. That's harmless; a change in your bowel habit lasting weeks isn't something to put down to exercise, so see a GP.
No single move has been shown to help. Moving first (a walk or a march), breathing into your ribs, gentle all-fours and side-lying moves, and knee hugs suit a sluggish or bloated tummy, and letting your pelvic floor relax helps if you strain. Our bloating class and morning routine for constipation put these together.
After a light meal, upright moves are fine. Leave lying flat, curling and head-down moves for about 2 hours after a big meal, especially if you get reflux. A 10 to 15-minute walk after meals eased fullness and bloating in a trial.
No study shows this. Twists are fine to do if they feel good, but the claim that they wring out, massage or detox the organs is untested.
Not directly. A swollen tummy is mostly a reflex in the diaphragm and tummy wall, not weak muscles, and specialist breath and tummy-wall retraining cut swelling by about half or more in trials. Breathing into your ribs with your lower tummy gently in points the same way, but it hasn't been tested.
It may help a little, as being active does: Cochrane found activity may improve IBS symptoms, though the evidence is very uncertain. Diet, medicines and talking therapies have more evidence. Our Pilates for IBS guide covers good and bad days.
Straining can mean the pelvic floor tightens when it should relax, and squeezing it more won't fix that. Practise letting go, rest your feet on a low stool so your knees are above your hips, and see a GP: specialist biofeedback helped 80% of people in a trial.
Breathing training eased reflux symptoms a little in small trials, and bearing down brings reflux on. Keep Pilates upright after meals and never hold your breath and strain. Our Pilates for acid reflux guide has the details.
Yes. The NHS says "Farting, also known as flatulence or wind, is normal.", and moving helps gas pass. A stomach ache that is severe and came on suddenly, or comes with vomiting or bleeding, needs urgent help.
For blood in your poo, a change in your bowel habit, losing weight without trying, a lump in your tummy, or bloating that won't go away. Try not to be embarrassed: doctors are used to talking about these symptoms.
Exercise education, not a personal prescription, and clinical review of these guides is pending. If you are pregnant, have a health condition or have had recent surgery, check with a doctor, midwife or physiotherapist before starting, and stop for sharp or increasing pain. Health disclaimer.
