Medical note: Ask your doctor or midwife before starting a new exercise routine. Pregnancy complications can change which activities are suitable for you.
Is exercise safe in the third trimester?
Most healthy pregnant women can exercise during pregnancy. Moderate activity can continue when your pregnancy remains healthy and uncomplicated. Late pregnancy may change balance, breathing, joint comfort, and energy. Adjust pace, duration, or movement choice when your body needs less effort.
Previous exercise experience also affects a suitable starting level. New exercise should begin with short, comfortable sessions. Experienced exercisers may continue familiar activity after medical discussion.
How much exercise is enough during the third trimester?
Aim for at least 150 minutes of moderate aerobic activity weekly. Spread those minutes across several days to match your energy. Moderate effort raises breathing, yet normal conversation remains possible. Lower the pace when talking becomes difficult during movement.
Women new to exercise can begin with five-minute sessions. Add time in small steps as comfort and stamina allow.
| Quick check | Practical target |
|---|---|
| Weekly aerobic activity | At least 150 moderate minutes |
| Effort | Normal conversation remains possible |
| New exercise | Begin with short sessions |
| Muscle work | Add light resistance on suitable days |
Before starting a third trimester workout
Late pregnancy workouts need enough water, stable footing, and comfortable clothing. A short warm-up prepares your joints and muscles for movement.
- •Drink water before, during, and after each workout.
- •Wear supportive shoes on a dry, stable surface.
- •Choose a cool room during hot or humid weather.
- •Warm up with gentle walking or easy joint movements.
- •Leave enough space for your growing abdomen.
- •Use hand support when balance becomes less secure.
- •Cool down with easier movement after your workout.
Pregnancy exercise advice recommends water, comfortable clothing, warming up, and cooling down.
9 third trimester exercises to consider
These third trimester exercises cover cardio, muscle work, mobility, and pelvic floor control. Walking, swimming, squats, wall push-ups, band work, and yoga suit many pregnancies. Pick only movements that remain comfortable and medically suitable.
1. Walking
Walking is one of the easiest third trimester cardio choices. It needs little equipment and works well at different speeds. Choose level ground when your balance changes.
Shorter walks may suit days with heavier fatigue. Supportive shoes can improve grip on damp or uneven surfaces. Lower your pace when normal conversation becomes difficult.
2. Swimming and water exercise
Water takes some weight off your joints during movement. Swimming and water walking can make late pregnancy exercise more comfortable.
- •Choose easy laps when continuous swimming remains comfortable.
- •Try water walking when you prefer lower effort.
- •Use pool steps or handrails around slippery areas.
- •Choose prenatal aqua classes with trained instructors.
- •Leave the pool when dizziness or unusual breathlessness appears.
3. Stationary cycling
Stationary cycling offers cardio without outdoor traffic or uneven ground. A fixed bike also reduces the fall risk from road cycling.
Adjust the seat until your knees remain slightly bent.
Choose light resistance for the first few minutes.
Use an upright posture with enough abdominal space.
Lower resistance when leg fatigue changes your posture.
Finish cycling if pelvic, knee, back, or abdominal pain appears.
4. Pelvic floor exercises
Pelvic floor exercises train muscles around your bladder, vagina, and bowel. Pregnancy places extra load on these muscles as your uterus grows.
Choose a comfortable seated or side-lying position. Gently tighten muscles around your vagina and back passage. Breathe normally while holding a comfortable contraction. Release every contraction fully before repeating the movement.
Research from 30 clinical trials included 6,691 pregnant participants. Researchers found a lower risk of urine leakage after pelvic floor training. Pelvic pain or worsening symptoms need medical advice.
5. Supported squats
Supported squats work your thighs, hips, and bottom muscles. Hand support can make the movement easier to control.
- •Hold a sturdy chair, wall, or kitchen counter.
- •Place your feet where your hips remain comfortable.
- •Bend your knees through a pain-free range.
- •Return upright slowly while breathing normally throughout the movement.
- •Use a smaller squat when pelvic discomfort appears.
6. Wall push-ups
Wall push-ups work your chest, shoulders, and arms. Wall support removes the floor balance needed for standard push-ups. Use enough space for your abdomen throughout each movement.
Place both palms against a stable wall.
Step backward until your body forms a gentle angle.
Bend both elbows and move your chest toward the wall.
Press away while breathing normally and controlling your posture.
Move closer to the wall when resistance becomes uncomfortable.
7. Resistance band rows
Resistance band rows work your upper back and arms. Light band work can suit pregnancy when resistance remains comfortable.
| Part | Movement |
|---|---|
| Setup | Secure the band near chest height. |
| Pull | Move both elbows backward with relaxed shoulders. |
| Return | Release the band slowly with full control. |
| Adjust | Choose lighter resistance when posture starts changing. |
8. Modified prenatal yoga
Modified prenatal yoga combines mobility, breathing, and controlled movement. Choose pregnancy classes with instructors trained in prenatal movement. Tell the instructor your pregnancy week before class begins.
Use wider positions when balance changes during late pregnancy. Add blocks or chairs when extra support improves comfort. Change poses when your growing abdomen needs more space. Leave any pose causing pain, dizziness, numbness, or abdominal discomfort.
Avoid hot yoga and long periods flat on your back. Choose another position when balance becomes difficult.
9. Standing pelvic tilts
Standing pelvic tilts move your lower back without floor work. Wall support can make the movement easier during late pregnancy.
Rest your shoulders and bottom against a wall.
Let both knees remain soft while breathing normally.
Gently draw your abdomen inward toward your spine.
Move your lower back toward the wall.
Hold briefly, then release with full control.
End the movement when pain or dizziness appears.
Can third trimester exercise prepare your body for labour?
Regular activity can improve fitness and stamina before birth. Pregnancy exercise may also reduce back pain and some pregnancy complications. No exercise can promise shorter labour or vaginal birth.
Use exercise for general health, mobility, and daily physical function. Ask your doctor or midwife about activity near your due date.
Which exercises should you avoid in the third trimester?
Avoid activities with high fall, collision, overheating, or abdominal impact risk. Late pregnancy balance changes can make some sports harder to control.
| Avoid | Main concern |
|---|---|
| Contact sports | Abdominal impact or collision |
| Horse riding, gymnastics, downhill skiing | Higher fall risk |
| Hot yoga or hot Pilates | Overheating |
| Scuba diving or skydiving | Serious pregnancy safety risks |
| Long periods flat on your back | Dizziness and reduced blood return |
Outdoor cycling may become harder when balance changes. A stationary bike can offer a lower fall risk option. Avoid heavy lifting that causes pain or exceeds medical advice.
When should you stop exercising during pregnancy?
Stop exercise when warning signs appear during pregnancy activity. Contact your doctor or maternity team when any symptom below occurs.
- •Vaginal bleeding or fluid leaking from the vagina.
- •Chest pain or breathlessness before exercise begins.
- •Dizziness, faintness, or a headache during your workout.
- •Abdominal pain or regular painful contractions during exercise.
- •Calf pain or sudden swelling in either leg.
- •Muscle weakness that starts affecting your normal balance.
Reduced baby movement also needs prompt contact with your maternity team. End your workout and follow medical instructions after any warning sign.
When should you ask your doctor before exercising?
Speak with your doctor or midwife when pregnancy complications affect physical activity. Medical advice becomes important before starting, continuing, or changing exercise.
Check first if your doctor diagnosed pre-eclampsia or placenta previa. Ask again with twins, later pregnancy bleeding, broken waters, or a short cervix. These pregnancy conditions may need individual medical advice.
Long-term health conditions can also change pregnancy exercise choices. Ask your doctor before exercise when a long-term condition needs monitoring. Your medical history can affect suitable activity and intensity.
