Exercise During Pregnancy: Safe Workouts and Guidelines

Exercise during pregnancy benefits both you and your baby—improving energy, reducing discomfort, preparing for labor, and supporting recovery. With appropriate modifications, most women can and should stay active throughout pregnancy.

Important: Always consult your healthcare provider before starting or continuing exercise during pregnancy. This guide provides general information, not medical advice.

Benefits of Prenatal Exercise

For You

• Reduced back pain and discomfort
• Better sleep
• Improved mood and energy
• Healthier weight gain
• Reduced risk of gestational diabetes
• Shorter labor and easier delivery
• Faster postpartum recovery

For Baby

• Healthier birth weight
• Better stress tolerance
• Potential cognitive benefits

General Guidelines

How Much Exercise?

ACOG recommends: 150 minutes of moderate-intensity exercise per week (about 30 minutes, 5 days per week).

If you were active before: You can generally continue your routine with modifications.

If you were sedentary: Start slowly—even 10 minutes daily is beneficial.

Intensity Guidelines

The talk test: You should be able to carry on a conversation during exercise.

RPE (Rating of Perceived Exertion): Aim for 12-14 on a 6-20 scale (somewhat hard).

Avoid: Exercising to exhaustion, getting overheated, or pushing through pain.

Safe Exercises by Trimester

First Trimester (Weeks 1-12)

Most activities can continue with awareness of early pregnancy symptoms.

Good options:

• Walking
• Swimming
• Stationary cycling
• Light strength training
• Yoga (prenatal-modified)
• Low-impact aerobics

Consider:

• Fatigue and nausea may limit exercise
• Stay hydrated
• Avoid overheating

Second Trimester (Weeks 13-27)

Often the most comfortable time for exercise.

Good options:

• All first trimester activities
• Prenatal fitness classes
• Water aerobics
• Modified strength training

New considerations:

• Avoid lying flat on back for extended periods (after week 20)
• Balance changes—be careful with stability
• Modify exercises as belly grows

Third Trimester (Weeks 28-40)

Focus on comfort and preparation for labor.

Good options:

• Walking
• Swimming and water exercise
• Prenatal yoga
• Light resistance training
• Pelvic floor exercises

Considerations:

• Lower intensity as needed
• Shorter sessions may be more comfortable
• Focus on maintaining rather than building fitness
• Prioritize comfort and safety

Recommended Activities

Walking

The most accessible exercise for pregnancy.

• No equipment needed
• Adjustable intensity
• Low injury risk
• Can continue throughout pregnancy

Swimming and Water Exercise

Excellent for pregnancy:

• Water supports body weight
• Reduces joint stress
• Helps with swelling
• Keeps you cool

Prenatal Yoga

Benefits flexibility, breathing, and relaxation.

• Use prenatal-specific modifications
• Avoid hot yoga
• Skip deep twists and lying flat on back
• Focus on breath work

Stationary Cycling

Safe cardiovascular option:

• Low impact
• Adjustable intensity
• No balance concerns
• Recumbent may be more comfortable later

Strength Training

Maintains muscle and supports changing body:

• Use moderate weights
• Avoid lying flat on back (modify or incline)
• Focus on form
• Include functional movements

Pelvic Floor Exercises (Kegels)

Essential throughout pregnancy:

• Contract pelvic floor muscles
• Hold 5-10 seconds
• 10-15 repetitions, 3 times daily
• Supports bladder, bowel, and delivery

Exercises to Avoid

High-Risk Activities

• Contact sports (basketball, soccer, hockey)
• Activities with fall risk (skiing, horseback riding, cycling on roads)
• Scuba diving
• Hot yoga or exercising in extreme heat
• High-altitude activities (above 6,000 feet if not acclimatized)

Movements to Modify or Avoid

• Lying flat on back (after 20 weeks)
• Deep twisting
• Heavy lifting
• Exercises that strain abdominals (crunches, sit-ups)
• Jumping and high-impact movements (later in pregnancy)
• Holding breath during exertion

Important Modifications

Avoiding Supine Position

After 20 weeks, lying flat on your back can compress blood vessels.

Instead:

• Use incline bench (30°+ angle)
• Side-lying exercises
• Standing or seated alternatives

Core Exercise Modifications

Traditional ab exercises aren't appropriate, but core work is still important:

Do:

• Bird dogs
• Modified planks (on knees, shortened duration)
• Pallof presses
• Pelvic floor exercises

Avoid:

• Crunches and sit-ups
• Full planks (later pregnancy)
• Exercises that cause abdominal doming

Diastasis Recti Awareness

Separation of abdominal muscles is common. To minimize:

• Avoid exercises that cause belly to dome or cone
• Roll to side when getting up from lying
• Engage deep core before lifting

Warning Signs to Stop Exercise

Stop and contact your provider if you experience:

• Vaginal bleeding
• Fluid leaking from vagina
• Dizziness or feeling faint
• Headache
• Chest pain
• Shortness of breath before exertion
• Calf pain or swelling
• Uterine contractions
• Decreased fetal movement
• Abdominal or pelvic pain

Conditions Requiring Medical Clearance

Some conditions require specific guidance:

• History of preterm labor
• Placenta previa
• Preeclampsia
• Severe anemia
• Certain heart or lung conditions
• Multiple pregnancy (twins, etc.)
• Cervical insufficiency

Always discuss your specific situation with your provider.

Practical Tips

Staying Cool

• Exercise in air conditioning or cool environments
• Stay well-hydrated
• Avoid peak heat hours
• Wear breathable clothing

Hydration

• Drink before, during, and after exercise
• Monitor urine color (pale yellow = well-hydrated)
• Increase intake in hot weather

Nutrition

• Eat enough to support exercise and pregnancy
• Small snack before exercise if needed
• Don't exercise fasted if it causes problems

Clothing

• Supportive sports bra (breasts grow!)
• Supportive shoes
• Maternity workout wear as needed
• Belly support band if helpful

Sample Weekly Schedule

Active Throughout Pregnancy

Monday: 30-min walk + prenatal yoga Tuesday: 30-min swim or water aerobics Wednesday: Light strength training (20-30 min) Thursday: 30-min walk Friday: Prenatal yoga Saturday: 30-45 min hike or longer walk Sunday: Rest or gentle stretching

Starting Exercise During Pregnancy

Week 1-2: 10-15 min walking, 3× per week Week 3-4: 15-20 min walking, 4× per week Week 5-6: 20-25 min walking, 5× per week Week 7+: Add variety (swimming, prenatal yoga, light strength)

Postpartum Considerations

Early Postpartum

• Rest and recovery first
• Walking when comfortable
• Pelvic floor exercises (when cleared)
• Wait for provider clearance for more intense exercise

Return to Exercise

• Typically 6 weeks for vaginal delivery
• Typically 8-12 weeks for cesarean
• Pelvic floor assessment recommended
• Progress gradually

The Bottom Line

Exercise during pregnancy is safe and beneficial for most women. Stay active, modify as needed, listen to your body, and maintain communication with your healthcare provider.

Keys to success:

1. Get clearance—discuss exercise with your provider
2. Listen to your body—adjust intensity and activities as needed
3. Stay cool and hydrated—avoid overheating
4. Modify appropriately—adapt exercises as pregnancy progresses
5. Know warning signs—stop and seek care if something feels wrong

Your body is doing incredible work. Support it with movement.

Safe exercise = healthier pregnancy.
