Pelvic floor exercises for pregnant women aren't optional in your third trimester. They're essential preparation for birth and recovery.
Your pelvic floor supports everything: your growing baby, your bladder, your core stability. Strengthening these muscles now means better control during labor, faster postpartum healing, and reduced risk of incontinence.
This guide covers safe, effective exercises for late pregnancy, including Kegels, pelvic tilts, and breathing techniques. You'll learn what to avoid, how often to exercise, and how to create a sustainable routine that supports your changing body without causing strain.
Why Pelvic Floor Exercises Matter in Your Third Trimester
Understanding Your Pelvic Floor Muscles
Your pelvic floor muscles form a hammock-like structure at the base of your pelvis, stretching from your pubic bone to your tailbone [1]. These layers of muscles, ligaments, and connective tissue support your bladder, uterus, and bowel while controlling the release of urine, stool, and gas [2]. Think of your pelvis as a bowl with the pelvic floor muscles making up the bottom, holding your internal organs in place [3].
These muscles do more than provide structural support. They stabilize your core, assist with bodily functions, and play a role in sexual function [2]. During pregnancy, they carry the weight of your growing baby while maintaining continence and pelvic stability [4]. The pelvic floor also contains multiple nerves that provide both function and sensation to the pelvic region [5].
How Pregnancy Affects Your Pelvic Floor
Pregnancy places significant strain on your pelvic floor muscles. The growing uterus adds pressure, with extra weight from the baby, placenta, and fluids bearing down on the area [1]. Hormonal shifts compound this mechanical stress. Rising levels of relaxin and progesterone relax ligaments and muscles to prepare for birth, but this reduces pelvic floor support [1]. Your vagina becomes more relaxed, causing additional strain as pregnancy progresses [3].
Research shows pelvic floor muscle strength is often classified as weak from the start of pregnancy [1]. By the third trimester, up to 92.8% of women report at least one symptom such as urinary incontinence or prolapse [1]. Bladder and prolapse symptoms are frequent throughout pregnancy but significantly intensify in the final months [1].
The statistics paint a clear picture. Urinary incontinence affects 26-70% of expectant mothers, with stress urinary incontinence being most prevalent [1]. Prolapse symptoms occur in about 10.8%, while bowel issues impact 36.3% [1]. Overall, 60.8% of women experience at least one pelvic floor disorder symptom during pregnancy, intensifying in later trimesters [1]. These symptoms negatively affect social and physical functions, restrict daily activities, and reduce overall quality of life [1].
Postpartum issues persist for many women. One in three women experience urinary leakage three months after pregnancy, while one in five have accidental bowel leakage one year after pregnancy [4]. One in 12 women report symptoms of pelvic organ prolapse [4].
The Link Between Pelvic Floor Strength and Childbirth
Pelvic floor muscle training improves outcomes during labor and delivery. Studies show PFMT facilitates the birthing process, reduces severe perineal tears, and shortens the second stage of labor [6]. During labor, the pelvic floor needs to relax and lengthen to allow a baby to pass through [3]. Preparing these muscles beforehand means better control during contractions and potentially easier delivery [7].
Starting pregnancy with strong pelvic floor muscles decreases the damage these muscles experience under the strain of carrying a growing child [7]. PFMT increases muscle endurance and fast twitch values during pregnancy, with effects more pronounced compared to women who don't train these muscles [6]. Strong pelvic floor muscles lead to faster recovery after childbirth, whether you deliver vaginally or through C-section [7].
PFMT also prevents venous stasis by increasing blood circulation in the pelvic region [6]. Since pelvic floor muscle arteries supply blood to vulvovaginal tissues, training may improve blood flow in these tissues and potentially affect uteroplacental and fetal circulation [6].
Essential Pelvic Floor Exercises for Third Trimester
Four core exercises strengthen your pelvic floor during your third trimester. Master these movements to prepare your body for labor and postpartum recovery.
Basic Kegel Exercises: Step-by-Step Guide
Kegels strengthen the muscles you use to stop urination or passing gas [1]. To locate these muscles, squeeze as if preventing yourself from peeing or farting, then relax [1]. You can place a clean finger in your vagina and squeeze around it to confirm you're engaging the right muscles [1].
Once you've identified your pelvic floor muscles, follow this routine:
-
Sit or lie comfortably with knees bent and muscles relaxed [1]
-
Squeeze and lift the pelvic floor muscles, holding for 5-10 seconds [8]
-
Relax completely for the same duration [1]
-
Repeat 8-10 times per set [1]
-
Perform at least 3 sets daily [1][1]
Avoid tightening your stomach, thighs, or buttocks during the exercise [8]. Breathe normally instead of holding your breath [1]. As pregnancy progresses, switch to anti-gravity positions like kneeling on all fours or side-lying to reduce pelvic floor load [8].
Pelvic Tilts for Strength and Stability
Pelvic tilts relieve lower back pain and encourage neutral pelvic alignment [4]. The sitting pelvic tilt exercise decreases back pain intensity during the third trimester without causing preterm labor or low birth weight [9].
For quadruped pelvic tilts, start on hands and knees with a neutral pelvis [4]. Exhale while engaging your core and pelvic floor, tucking your pelvis to bring your pubic bone toward your ribcage [4]. Hold briefly, keeping the rest of your body still, then return to neutral on the inhale [4]. Perform 6-8 repetitions [4].
Standing pelvic tilts work similarly. Stand against a wall with shoulders and bottom touching the surface [8]. Pull your belly button toward your spine and flatten your back against the wall [8]. Hold for 4 seconds and release [8]. Repeat up to 10 times [8].
Squats with Pelvic Floor Activation
Research suggests squats are up to 30% more effective than Kegels for strengthening pelvic floor muscles [10]. Squats engage both muscles and joints dynamically while Kegels target muscles only [10].
Stand with feet shoulder-width apart and toes slightly turned out [1]. Lower your hips as if sitting in a chair, keeping your chest lifted and knees behind toes [1]. Press through your heels to return to standing [1]. Inhale as you lower, then exhale while bracing your core and lifting your pelvic floor as you rise [10]. Aim for 2-3 sets of 8-10 repetitions [10].
For wall squats, press your back against a wall and slowly lower into a sitting position [10]. Hold for 30 seconds to 1 minute while practicing deep breathing [10].
Deep Breathing Techniques for Pelvic Floor Relaxation
Diaphragmatic breathing coordinates your pelvic floor with your diaphragm [11]. When you inhale, your diaphragm descends, causing your pelvic floor to lengthen and soften [11]. During exhalation, the pelvic floor recoils upward and your core engages [11].
Sit or lie comfortably and breathe slowly through your nose, drawing air toward your low belly [8]. Your belly, ribcage sides, and lower back should gently expand [8]. Exhale slowly through your mouth, allowing your abdomen to recoil naturally [8]. Practice for 5-10 minutes [8].
This breathing pattern activates the parasympathetic nervous system, lowering heart rate and reducing stress hormones [11].
Safe Third Trimester Exercises to Complement Pelvic Floor Work
Complementary exercises support your pelvic floor work by strengthening surrounding muscles, improving circulation, and maintaining overall fitness. Physical activity during pregnancy is associated with decreased excess weight gain, gestational diabetes, preeclampsia, lower back pain, and better fitness [12]. These low-impact activities keep you strong without straining your pelvic floor.
Prenatal Yoga and Stretching
Prenatal yoga builds core stability while encouraging relaxation and deep breathing [9]. Research shows yoga eases anxiety and depression during pregnancy, with women reporting mood improvements, decreased pain, and lower incidence of preterm labor and Cesarean delivery [9]. Classes designed for pregnant women modify poses for safety and comfort as your baby grows.
Focus on hip openers, gentle stretches, and breathing work in your third trimester [13]. Warrior II improves circulation, strengthens your whole body, and opens hips while relieving neck and back pain [13]. Garland pose opens hips and boosts digestion, though you should avoid it if prone to prolapse [13]. Bridge pose temporarily alleviates pressure in your pelvic bowl [14]. Child's pose with wide knees provides a comfortable resting position, placing a bolster under your torso to accommodate your belly [14].
Avoid intense backbends, forceful abdominal contractions, inversions, lying on your back for extended periods, and hot yoga [13]. The hormone relaxin increases during pregnancy, making you more flexible but also more prone to overstretching and injury [15].
Swimming and Water-Based Activities
Swimming ranks among the safest forms of exercise during pregnancy [4]. Water supports your weight, relieves joint pressure, and helps prevent overheating [9]. Just being in water reduces swelling as effectively as medication [16]. Submerging your limbs pushes fluids from tissues back into your veins, boosting circulation and reducing ankle and foot swelling [17].
Water-based exercise alleviates sciatic pain, morning sickness, and puffy ankles [18]. Swimming maintains muscle tone and increases endurance, both beneficial for labor and delivery [17]. Keep sessions to about 30 minutes and limit to 3-5 times weekly [4]. Stay hydrated even while swimming, as you still sweat during water workouts [4]. Avoid diving, jumping in, or swimming in hot water [19].
Walking and Gentle Cardio
Walking during late pregnancy achieves cervical ripening and spontaneous onset of labor while improving Bishop score and decreasing induction, cesarean, and instrumental delivery [12]. Moderate-intensity walking doesn't increase fetal developmental disorders or placental blood flow issues [12]. Aim for 15-50 minutes daily, five to six days weekly, depending on your fitness level [20]. Stick to flat paths as your center of gravity shifts with your growing belly [21].
Light Resistance Training with Bands
Resistance bands provide a safe alternative to free weights with no risk of dropping weights on your belly [1]. Light resistance work strengthens muscles to support your pregnancy weight and protects joints as ligaments relax [18]. Rows, bicep curls, chest flies, and lateral raises with 2-5 pound dumbbells or bands build upper body strength [9][1]. Squats and lunges tone lower body muscles [22]. Contract your pelvic floor and core during the exertion phase of each exercise [23].
Exercises and Positions to Avoid in Late Pregnancy
Certain movements and positions become unsafe as your pregnancy advances. Knowing what to avoid protects both you and your baby during these final months.
Lying Flat on Your Back After 16 Weeks
After 16 weeks of pregnancy, avoid lying flat on your back for extended periods [24]. The weight of your baby presses on the inferior vena cava, the main blood vessel returning blood to your heart, which restricts circulation to you and your baby [24][25]. This compression makes you feel faint, nauseous, dizzy, and short of breath [10].
Research links supine sleep position in late pregnancy to increased stillbirth risk. Studies show this position is associated with more than double the odds of late stillbirth compared to side-sleeping [26]. Going to sleep on your side after 28 weeks reduces this risk [27]. If you wake up on your back, simply roll to your side without worry, as your body typically shifts positions before circulation becomes compromised [28].
High-Impact and Contact Activities
Contact sports carry risk of abdominal injury. Football, rugby, hockey, basketball, martial arts, and boxing should be avoided completely during pregnancy [24][25]. Your growing bump alters your center of gravity, making balance harder to maintain [24]. Activities with falling potential include skiing, climbing, horse riding, gymnastics, downhill snow skiing, off-road cycling, and rollerblading [24][10][25].
Scuba diving puts your baby at risk of decompression sickness [24][29]. Hot yoga raises your body temperature beyond safe levels [10][25]. Jumping, bouncing, and sudden jerky motions strain relaxed ligaments [10].
Heavy Lifting and Overhead Movements
Pregnancy hormones relax ligaments, increasing injury risk during lifting [11]. Recommended weight limits drop to less than 24 pounds for repetitive lifting and less than 31 pounds for intermittent lifting in the final weeks [11]. Avoid lifting from floor level with hands below midshin [11].
Overhead lifting requires caution. Reduce weight to 70% of your one-rep max in the second trimester and 50% in the third trimester [30]. Poor form during overhead movements risks dropping weights on your belly [30].
Exercises That Cause Abdominal Coning
Abdominal coning or doming indicates excessive intra-abdominal pressure that worsens diastasis recti [8][31]. Stop exercises that bulge your abdominal muscles forward forcefully or cause pain [8][31]. Avoid crunches, sit-ups, bicycle crunches, double leg lifts, full planks, push-ups without modifications, Russian twists, and traditional Pilates roll-ups [8][31][32]. These movements strain overstretched tissue at your abdomen's center, potentially leading to hernias or pelvic floor prolapse [8].
Creating Your Third Trimester Workout Routine
Building a sustainable routine ensures pelvic floor exercises for pregnant women become habit rather than afterthought.
How Often to Exercise Your Pelvic Floor
Aim for 3 sets of 8 squeezes daily [29]. Repeat both slow and fast contractions 3-4 times throughout your day [33]. Some experts recommend up to 40 sets daily for optimal strength [34]. Training takes time. Commit to at least three months of daily practice, then reduce to a few sessions weekly for maintenance [33]. Squeeze your pelvic floor every time you cough or sneeze to prevent leakage [33][35].
Combining Pelvic Floor Work with Daily Activity
Link exercises to routine activities. Practice while washing dishes, waiting for your phone to ring, or cooking dinner [33]. Squeeze while standing in queues, waiting for the kettle to boil, or sitting at red traffic lights [36]. Setting phone alarms or placing reminder stickers on your fridge and bathroom mirror keeps you consistent [35].
Sample Weekly Exercise Schedule
Monday: Prenatal yoga 30 minutes, walking 20 minutes
Tuesday: Light weights 20 minutes, pelvic floor exercises 10 minutes
Wednesday: Swimming 30 minutes
Thursday: Prenatal Pilates 30 minutes, walking 20 minutes
Friday: Bodyweight exercises 20 minutes, pelvic floor exercises 10 minutes
Saturday: Low-impact cardio 30 minutes
Sunday: Rest or gentle stretching [37]
Listening to Your Body and Adjusting Intensity
Stop exercising if you experience pain, dizziness, or excessive fatigue [37]. You should hold conversations comfortably during workouts [13]. Adjust positions as needed, starting lying down if standing feels too challenging [38]. Rest when your body demands it, even if that means more than two days weekly [14].
Conclusion
Strong pelvic floor muscles transform your birth experience and recovery. The exercises in this guide give you everything needed to prepare your body for labor and protect against postpartum complications. Consistency matters primarily, given that results develop over weeks of daily practice, not overnight.
Start with basic Kegels, add squats and breathing techniques, then build a sustainable routine around your daily activities. Your body will signal when adjustments are necessary, so pay attention and modify accordingly. These simple exercises take minutes daily but deliver benefits lasting years beyond pregnancy. Commit to the work now, and you'll notice the difference during delivery and well into motherhood.
