Kegel exercises in the second trimester: the sweet spot.

The nausea has lifted, the bump hasn't taken over yet, and this is the window where a pelvic floor habit actually sticks.

6 min read·Grounded in published research, sources

The first trimester was survival. The second is when this actually becomes doable. For a lot of people, roughly weeks 13 to 27 are the stretch where the nausea lifts, some energy comes back, and the bump hasn't yet started dictating how you sit. That's why second trimester Kegel exercises deserve a plan rather than an intention: this is the window where a pelvic floor habit can genuinely stick, and it's also when the reason for having one starts to make itself felt. The load on your pelvic floor climbs from here, and if a cough has already caught you out, you're in very ordinary company. If you're only starting now, the first trimester guide covers finding the muscle from scratch.

Second trimester Kegel exercises: why this is the sweet spot

Three things line up in this trimester. Your energy is usually better than it was. The load on your pelvic floor is rising but hasn't peaked. And the payoff is still ahead of you, which is exactly when training is worth doing.

That last point is the one worth sitting with. Leaking becomes steadily more common as pregnancy goes on, and the research on pelvic floor training in pregnancy points the same way: the clearest benefit shows up in people who train before leaks become established. If nothing has started yet, a small daily habit has the most to work with right now. If something has started, training is still worth doing, but be realistic about it, and read the leaks section below.

There's a practical argument too. Whatever you build now, you'll be leaning on after the birth, when a spare minute and a functioning brain are much harder to come by. Learning the move while you still have the calm is the whole idea.

Positions that work now (and when to switch)

In the first trimester any position works. From here on, they start behaving differently, and swapping position is usually the fix when a Kegel stops feeling like anything.

Side-lying
The easiest place to feel the lift for most people. Best when you're tired, heavy, or brand new to the move. Lying flat on your back is the one to avoid from around this point: general exercise guidance in pregnancy is to keep off your back as much as possible, because the uterus presses on a large vein returning blood to your heart, which can briefly drop your blood pressure. Roll onto your side or prop yourself up instead.
Sitting
The workhorse, and the one that survives the whole pregnancy. Sit tall rather than slumped, both feet on the floor, and let your belly stay soft. This is the position you can use at a desk, in the car, or in a waiting room without a single person noticing.
Standing
The hardest, and worth keeping in the mix, because standing is where most of the pressure moments happen: the cough, the sneeze, the lift. Expect it to get harder as the weight builds; that's the load increasing, not you going backwards. If you can only manage a couple of good reps standing, do a couple of good reps standing.
On all fours
Worth knowing about for the days when everything feels heavy and nothing else is comfortable. Plenty of people find it the easiest position to breathe and release in, which makes it a good one for practicing the letting-go half.

The cue for switching isn't a date in the calendar, it's a feeling. When a position stops letting you feel the lift, or it's simply uncomfortable, change it. Dizziness or breathlessness is a different signal: the standard advice on exercise in pregnancy is to stop and check in with your midwife or doctor, not to work around it. Most people drift from standing towards sitting and side-lying as the months go on, and there's nothing wrong with that. Working in more than one position is standard advice anyway, so treat the drift as part of the plan.

If you've started leaking

First, the reassurance, because this is the bit people are embarrassed to ask about. In pooled studies, roughly four in ten women reported some leaking at some point in pregnancy, and the stress kind (cough, sneeze, laugh, lift) was by far the most common. It's pressure briefly winning, not a failure of yours, and it becomes more common as the weeks add up.

Two things to do about it. The first is the daily practice below. The second is a trick called the Knack: tighten and lift your pelvic floor just before and during the cough, the sneeze, or the lift, bracing a beat ahead of the pressure. Practicing that timing is standard pregnancy advice, and it works alongside your daily reps rather than instead of them.

Now the honest part. The research on training as a treatment for leaks that have already started in pregnancy is much weaker than the research on preventing them in the first place. It's still the sensible first thing to try, and it's what you'd be pointed to first anyway, but we won't tell you it clears up for everyone. If it's heavy, or it's bothering you, mention it at your next appointment. The mechanics of all this are covered properly in Kegels for leaks when you sneeze, laugh, or run.

How much, how often

Numbers first, caveat second. One common recommendation is around three sets of eight squeezes every day, mixing slow holds with quick ones. Another widely used version works up to 10 to 15 repetitions, three times a day, practiced in more than one position. Both land in the same place: a small amount, most days, spread through the day rather than done in one heroic block.

If you're starting from nothing, start under those numbers. Three good reps you actually do beat eight rushed ones you don't, and the count is the easiest thing to add later. A pelvic floor professional can tailor the numbers to you, which is worth doing if anything about your pregnancy needs watching.

On timing, expect weeks rather than days. Bladder control often doesn't feel different for the first three to six weeks, and strength keeps building well past that. Pregnancy adds a wrinkle: the load on your pelvic floor is increasing at the same time you're training it, so "no change" isn't the same as "nothing happening". Worth remembering before you decide it isn't working.

Don't chase a stronger squeeze

There's a version of this that goes wrong, and it's the enthusiastic version. More is not better here. A pelvic floor held in a permanent half-clench is a tense one, not a strong one, and tightness brings its own set of problems: pain, urgency, trouble relaxing, discomfort during sex. The full letting-go at the end of every rep is the part to protect.

Signs you've overcooked it: aching afterwards, a floor that never quite softens, pain when you contract. If that's the pattern, stop and get assessed rather than pushing harder. Reverse Kegels covers the release side in detail. And if you're gripping your glutes, bracing your jaw, or holding your breath to get a bigger squeeze, you're working hard in the wrong place.

Carrying it into the third trimester

The last stretch is heavier in every sense. The load keeps climbing, standing gets harder, the positions narrow, and the goal quietly changes from building to not losing the thread. Keep it small enough that you'll still do it at 36 weeks. Kegels in the third trimester covers that stretch in full, including the release work that matters for birth, and there's a wider view of the whole arc on pelvic floor exercises during pregnancy.

And the real reason to keep it going: the version of you at your postnatal check, being told to start pelvic floor exercises again, will be extremely glad this is already automatic.

Build it now, lean on it later.

When to see someone

Worth raising with your midwife or doctor: leaking that's heavy or bothering you, a feeling of heaviness or a bulge, pain when you contract, or pelvic girdle pain that changes how you walk. And if you've been told your pelvic floor is already tight or overactive, get a pelvic floor physiotherapist's opinion before you add more squeezing, because release work may matter more for you. Strengthening helps a great many people; it isn't the right answer for everyone.

Frequently asked

Are Kegel exercises safe in the second trimester?

For an uncomplicated pregnancy, ACOG says physical activity in general is safe and desirable. For the pelvic floor specifically, training is commonly recommended during pregnancy. A clinical evaluation still comes first, because bleeding, painful contractions or other medical or obstetric complications can change the advice for you. Pelvic floor exercises throughout pregnancy

What position should I use for pelvic floor exercises in the second trimester?

Use a position where you can feel a gentle squeeze and a full release without bracing your belly. NIDDK lists lying down, sitting and standing, while ACOG says maintaining a flat-on-your-back exercise position after 20 weeks can reduce blood return and may lower blood pressure. Side-lying, sitting or standing are practical alternatives; the position is about comfort and technique, not proof of a stronger result. Getting the movement right

Is urine leakage at 20 weeks of pregnancy normal?

Urinary leakage is common in pregnancy and becomes more prevalent as the weeks go on, but common is not the same as normal and does not mean you should leave it unsaid. The NHS advises speaking to a clinician about any urinary incontinence, so tell your doctor or midwife, more so if the leakage is heavy or bothering you. For leakage that has already started during pregnancy, the treatment evidence for pelvic floor training is uncertain rather than guaranteed. Pelvic floor exercises for bladder leakage

How many pelvic floor exercises should I do each day in the second trimester?

The right count is the one your clinician or pelvic floor therapist sets for your technique and pregnancy. NIDDK advises asking a health professional for a plan that meets your unique needs; it also warns that overdoing the exercises can lead to straining when you urinate or move your bowels. Kegelia paces one minute without deciding how many sessions you need. How long pelvic floor training takes

Do pelvic floor exercises in the second trimester make birth easier?

Research does not give us a result we can promise for your birth. A review of antenatal pelvic floor exercise found no significant difference in vaginal birth, cesarean birth, instrumental birth or episiotomy, and most included studies had a moderate to high risk of bias. Practice can teach you the squeeze and the release; it cannot guarantee how labor, tearing or episiotomy will go. What the research does and does not say

When should I pause pelvic floor exercises in the second trimester?

Pause strengthening and ask for an assessment if contracting brings pelvic pain or trouble releasing the muscles. Pregnancy-related pelvic girdle pain is a separate problem with its own guidance; NICE advises considering referral to physiotherapy services for it. A nonrelaxing pelvic floor is its own condition, and early referral to pelvic floor physical therapy is part of its management. In the second trimester, stop exercising and call your pregnancy team for vaginal bleeding, abdominal pain, regular painful contractions, amniotic fluid leakage or dizziness.
