Pregnancy can change your balance, posture, mobility, and comfort from one trimester to the next. A good size exercise ball can offer a supportive surface for gentle movement, for seated mobility, for pelvic movement, for light strengthening and for relaxation. But an exercise ball is not necessarily safe just because it is called a “birth ball.” The right exercises, intensity, ball size, and medical guidance matter.
Regular exercise is recommended for most women who are not having complications. The American College of Obstetricians and Gynecologists (ACOG) advises that healthy pregnant women engage in at least 150 minutes of moderate-intensity aerobic exercise each week, but they should take individual medical factors and gradual progression into account.
The exercises below are designed as gentle examples rather than a substitute for individualized prenatal care. Talk to your obstetrician or midwife before exercising if you have pregnancy complications, pain, bleeding, contractions, dizziness or other concerns.

Quick Answer
The exercise ball can be utilized in pregnancy for gentle sitting, pelvic mobility, posture work, supported squats, stretching and relaxation. Use the right size anti-burst ball, set it on a nonslip surface and have a stable support like a wall or sturdy chair nearby.
A pregnancy ball session may be as simple as breathing, pelvic tilts, hip circles, supported squats, gentle weight shifts and a relaxation cool down. Maintain a comfortable level of intensity so that you can speak normally during exercise.
It is important to note that the use of a birth ball does not ensure induction of labor, a shorter labor or a vaginal delivery. Evidence indicates that the use of birth-balls during labor can decrease perceived pain, with conflicting results for other labor outcomes.
Why Use an Exercise Ball During Pregnancy?
Exercise Ball vs Birthing Ball vs Peanut Ball
The term “Exercise ball” is sometimes used synonymously with “Swiss ball,” “stability ball,” and “birth ball” to describe a large inflatable ball for sitting and moving on. A birthing ball is typically a round exercise ball that is utilized for comfort and movement during pregnancy or labor.
A peanut ball is shaped like a large peanut or two balls stuck together. It is commonly used in specific labor positions, particularly when a person is lying or sitting in bed. It should not be assumed that it is interchangeable with a round exercise ball.
Posture, Mobility and Low-Back Comfort
The center of gravity shifts during pregnancy, and can add stress to the pelvis and lower back. A ball can offer an unstable but supportive surface for gentle movement and can make seated pelvic mobility easier.
ACOG also mentions that falls and injuries may be more likely due to changes in balance and joint mobility during pregnancy, so movements should be controlled but not jerky or high impact.
Core and Pelvic Floor Coordination
Exercise during pregnancy doesn't have to be a lot of abdominal work. Rather, concentrate on breathing together, softening the trunk and being aware of the pelvic floor.
Breathe in as you normally would and then breathe out as you normally would, but with a gentle squeeze of the pelvic floor and lower abdominal muscles. The goal is coordination—not constant tightening. During pregnancy, pelvic floor exercises are recommended as they can help strengthen the muscles that support the bladder, uterus and rectum.
What Research Says About Exercise Balls and Labor Pain
Studies have shown that birth balls can be effective for pain relief during childbirth. A systematic review and meta-analysis of randomized trials revealed that birth-ball use was linked to reduced labor-pain scores.
The Journal of Maternal-fetal & Neonatal Medicine also reported reductions in pain and some labor-duration outcomes, although findings should not be interpreted as a guarantee for an individual pregnancy.
The Birth Ball is not a magical tool that ensures a woman will go into labor or that her labor will be quickened.
Why a Birth Ball Cannot Guarantee Labor Induction or a Faster Delivery
A birth ball is not a medical method of induction, it is a comfort and movement tool. There is no evidence that sitting, bouncing or exercising on a ball will reliably induce labor.
ACOG describes medically indicated and elective labor induction as clinical interventions with specific indications; a pregnancy ball should not be considered an alternative to medically appropriate induction when induction is recommended.
Safe Setup before Starting Your Workout
Selecting the appropriate ball size for height
The size of the balls will differ from manufacturer to manufacturer, so use the height and weight guidelines provided with the product, not just a generic chart.
Your hips should be at or just above knee level when sitting, and your feet should be flat on the floor. If the ball is too small, you may find yourself in an awkward position, and if it is too large, it could be more difficult to mount and balance.
Inspecting Hip and Knee Position When Sitting
Sit close to the middle of the ball with both feet on the ground. Your knees should not be pointing inwards.
If you are not able to maintain a stable position or feel like you are moving forward, stop and make adjustments.
Inflation, Anti-Burst Material, Weight Capacity
Inflate with a ball that supports your body weight and according to the manufacturer's instructions. An anti-burst design may offer an extra layer of protection in the event of a puncture, but it does not remove fall risk.
Check the ball frequently for cuts, cracks, leaks, or damage.
Creating a Non-Slip Workout Area with Stable Support
Put the ball on a hard, non-slip surface. Do not use loose rugs or slippery surfaces. A wall, heavy chair, countertop or other stable object nearby can make transitions safer during pregnancy.
How to Get On and Off the Ball without Falling
Avoid jumping on the ball. Keep the ball behind you, take a wide stance, put one hand on a stable surface and descend slowly.
Standing, lean slightly forward, keep feet flat on the floor and use the stable base to stand up.
When your balance is shifting dramatically in late pregnancy, you may want to have another adult around.
How to use an Exercise Ball as a Desk Chair Safely
Sitting on an exercise ball for short periods of time can help promote gentle postural changes, but it should not be used as a fall-proof chair for the office.
When working at a desk, ensure that your feet are supported and do not lean, reach or turn quickly. If you are tired or have balance problems, a conventional stable chair might be safer for extended periods of sitting.
Medical Clearance, Hydration, and the Talk Test
Moderate activity is usually recommended for a healthy, uncomplicated pregnancy. However, consult your maternity care provider about your exercise program, especially if you are beginning a new exercise program.
Drink water before, during, and after exercise. The talk test is useful: if you can comfortably hold a conversation while exercising, the intensity is generally moderate.
First Trimester: Exercise Ball Pregnancy Workout
Nausea, fatigue, breast tenderness and dizziness are common in the first trimester. Keep sessions short when necessary.
Seated 360-Degree Breathing with Pelvic Floor Lift and Release
Sit up straight, feet on the floor. Slowly breathe in, letting your ribs and belly expand naturally. Exhale and gently squeeze the pelvic floor, and relax it completely with the next inhale. Repeat for 5-8 comfortable breaths.
Seated Pelvic Tilts
Place your feet apart to be stable and roll your pelvis back and forth. Continue the movement gently and slowly. Perform 8–10 repetitions.
Slow Hip Circles
Sit and make small circles with hips. Walk slowly back and forth. Attempt 5 circles in each direction.
Seated Heel Raises
Slowly raise both heels, keeping toes on floor. Bring them down in a controlled manner. Perform 8–12 repetitions.
Seated Side Reach and Upper-Back Stretch
Sit up tall and stretch one arm slowly up gently over the head with a stable pelvis. Go back to center and cross over to the other side. Do not twist too deeply or stretch out beyond your reach.
Modifications for Nausea, Fatigue, and Dizziness
If it's a tough day, limit the session to breathing and gentle mobility. Exercising does not need to be an all-or-nothing activity.
If dizzy or faint, discontinue exercise and sit or lie in a safe place. ACOG lists dizziness and fainting among warning signs requiring exercise to stop and medical assessment.
Second Trimester: Stability and Low-Back Support Routine
As the abdomen grows, your center of gravity changes and balance may become more challenging. Select stability movements instead of challenging stability exercises.
Ball-Supported Wall Squats
Place the ball between your lower back and a wall. Keep feet slightly forward and lower only as far as comfortable.
Maintain control of the movement and use the wall for stability.
Standing Wall Ball Press with Exhale
With ball between your hands and wall, face the wall. Exhale and press the ball gently towards the wall, then release. This provides light upper-body resistance without requiring you to balance on the ball.
Seated Side-to-Side Weight Shifts
Sit firmly and move your weight a few centimeters towards one hip, then back to center, and then towards the other hip.
The movement should be slow enough that your feet do not lift off the ground.
Supported Seated March
Sitting up, raise one foot a few centimeters, then lower it, and repeat with the other foot. Hold a stable surface if necessary.
Stop if the ball moves excessively beneath you.
Kneeling Forward Ball Roll and Back Stretch
Sit on a comfortable mat with ball in front of you. Rest your forearms on it and slowly roll the ball forward keeping your hips comfortable.
Avoid forcing the stretch or letting the belly drop towards the ground.
How to Breathe Without Holding Your Breath
Do not hold your breath while exercising during pregnancy. Breathe out during the action part of a movement, and breathe in as you return.
Relaxed breathing pattern may also help to avoid unnecessary abdominal pressure.
Coning or Doming: When to Reduce the Load
During some movements, some pregnant people feel a ridge, bulge or “doming” in the middle of the abdomen. If this happens again and again, decrease the intensity, range, or load instead of trying to increase it.
If the abdominal wall is unable to be controlled, or if there is persistent abdominal separation, pressure, pain, or difficulty, it may be appropriate to seek evaluation from an obstetric clinician or pelvic health physical therapist.
Modifications for Pelvic Girdle, Sacroiliac Joint, or Pubic Pain
If the pain is around the pelvis, sacroiliac joints or pubic area, it should not be ignored. Reduce range of motion and avoid movements that worsen symptoms.
If walking, turning in bed, climbing stairs or getting dressed are painful, consult your maternity care provider for a pelvic health physical therapy assessment.
Third Trimester: Hip Mobility and Labor Preparation
A birth ball is especially helpful for standing in the third trimester. But the need for stability and fall prevention increases even more.
Wide-Knee Seated Pelvic Rocking
Sit comfortably with feet wide, gently rock pelvis forward and backward. Move slowly and deliberately.
Controlled Hip Circles and Figure-Eight Movements
Move hips in slow circles or small figure eights. These movements are meant to be for comfort and mobility, not to put the pelvis in a specific position.
Supported Side-Lunge Hip Opener
Stand next to a solid surface and step slightly to the side. Bend outside knee slightly, keeping opposite leg comfortable.
Avoid going too far into the lunge and discontinue if pain occurs in the pelvis or groin area.
Kneeling Forward Lean over the Ball
Rest upper body on ball while kneeling on a padded surface. This can give a comfortable supported position, while relaxing the shoulders. If you become unsteady, have someone nearby.
Gentle Side-to-Side Swaying
Slowly rock hips side to side while sitting. This may be performed as a relaxation movement in late pregnancy and, with the birth team's permission, during labor.
Controlled Bouncing in Late Pregnancy and Early Labor
Slow motion might be comfortable, but fast bouncing is not needed. Due to pregnancy, balance and joint stability are altered, so use small movements and avoid anything that feels unstable.
Using the Ball during Contractions with a Partner or Birth Team
Some find it comfortable to sit, rock, lean forward or circle on a birth ball during labor. You can get help from your partner or birth team to move into your new position.
How to Build a Complete 15-Minute Pregnancy Ball Workout
The pregnancy ball workout can be done in 15 minutes and offers gentle mobility, strengthening, breathing practice and relaxation without unnecessary stress on the body.
Three-Minute Breathing and Mobility Warm-Up
Begin with comfortable breathing, gentle pelvic tilts, small hip circles and shoulder rolls. Keep feet on ground and take it easy. The aim is to get your body ready, not to get your heart rate up.
Ten-Minute Trimester-Appropriate Movement Circuit
Select 3-4 exercises that are appropriate for your trimester. Do each for approximately 45-60 seconds, resting as necessary. Seated pelvic tilts, hip circles, supported wall squats, seated marching and slow side to side weight shifts are good choices. Pay attention to the quality of movement and ease of breathing.
Two-Minute Cooldown and Pelvic Floor Release
Complete with slow breathing and consciously relaxing the pelvic floor. When getting off the ball, take time to avoid losing balance.
Repetitions, Rest Periods, and Weekly Frequency
No one pregnancy-ball routine fits all. Begin with short sessions and build up activity as per comfort and healthcare provider's advice. For healthy pregnancies, ACOG recommends about 150 minutes of moderate-intensity physical activity each week, which can be divided into shorter sessions.
How to Progress Without Increasing Fall Risk
Make progress by adding control, consistency or duration of workout, not instability. Do not stand on the ball, bounce quickly, jump or do more advanced balancing activities.
When to Modify or Avoid Exercise Ball Workouts
Pregnancy Complications That Require Individual Medical Advice
Exercise restrictions may be necessary if there are conditions like vaginal bleeding, placenta-related complications, cervical concerns, and preeclampsia or preterm-labor concerns. If your pregnancy is complicated, follow your obstetrician's personal advice.
Avoiding Prolonged Flat-Back Positions after the First Trimester
Women must refrain from prolonged lying on their back during pregnancy while exercising. NHS guidelines also advise against exercises that involve spending a long time on your back, especially after 16 weeks.
Exercises with Excessive Instability or Fall Risk
Do not stand on the ball, jump, change direction quickly or perform balancing movements. Changes in your center of gravity and balance during pregnancy can make you more likely to fall.
Warning Signs That Mean Stop Exercising and Call Your Care Team
If you have bleeding from the vagina, leakage of fluid, painful contractions, chest pain, fainting, a lot of dizziness, unusual shortness of breath, severe headache, or calf pain or swelling, stop exercising and call your maternity care provider.
When Pain, Pressure, or Abdominal Doming Needs Assessment
If the pain in the pelvis is ongoing, or if the person feels heavy, pressured, or experiences leakage of urine, or if the abdomen is doming repeatedly, it should be professionally evaluated. A pelvic health physical therapist can give you personalized advice.
Postpartum Recovery with an Exercise Ball
Early Recovery Breathing and Gentle Pelvic Floor Coordination
The first few days after birth should be spent recovering. Breathing and pelvic floor awareness can start as soon as medically appropriate, and more challenging exercise can be added on a gradual basis.
Returning After a Vaginal Birth, C-Section, or Complicated Delivery
Gentle activity can be resumed when you feel ready after an uncomplicated vaginal birth. If you have had a C-section or a difficult birth, talk to your health care provider before taking steps.
Gradual Seated Mobility before Resuming Ball Workouts
Start with stable exercises (walking, gentle mobility, breathing and pelvic floor coordination) before moving on to ball exercises.
Checking for Diastasis Recti and Pelvic Floor Symptoms
If abdominal separation is still present, the pelvis is heavy, or there is leakage of urine or stool, or pain, a health care provider should evaluate the condition.
Partner-Assisted Ball Stretches: Spotting Without Forced Movement
A partner may stand close by for balance support, but should never push your hips, spine or limbs into a deeper stretch.
When to see a Pelvic Health Physical Therapist
A pelvic health physical therapist can help address pelvic pain, abdominal-wall concerns, pelvic floor coordination, and gradual return to exercise.
Grownsy products can also help make daily life easier as you prepare for your newborn. A bottle washer can help to clean bottles and a bottle warmer can help to prepare feeding. Later, a baby food maker can help prepare foods when your baby is ready for complementary feeding. For nursery preparation, a bassinet can support a dedicated sleep space, while a baby swing may provide supervised soothing when used according to safety instructions.
Conclusion
When used safely, an exercise ball can be a helpful pregnancy fitness tool. Emphasize gentle mobility, supported strengthening, comfortable breathing, and progressive movement. While birth balls can help to make labor more comfortable, they do not ensure labor induction or a quicker delivery. Always modify exercises during pregnancy and seek advice from your maternity care team if there are any concerns.
