Exercise Guidelines
Aim for 30 minutes most days of the week
Moderate intensity:
- Can talk but not sing
- Slightly breathless but comfortable
- Warm but not overheated
If you exercised regularly before pregnancy:
- Continue with modifications
- Maintain fitness (don’t aim for improvement)
- Listen to your body
If you were inactive before pregnancy:
- Start slowly (10-15 minutes)
- Gradually increase
- Low-impact activities best
- Get doctor approval first
Safe Exercises by Trimester
First Trimester (Weeks 1-12)
Generally can continue pre-pregnancy routine:
- Running (if you ran before)
- Weight lifting (moderate)
- Yoga and Pilates
- Swimming
- Cycling
Common challenges:
- Fatigue (may need more rest)
- Nausea (exercise may worsen or help)
- No visible changes yet
Listen to your body – rest when needed.
Second Trimester (Weeks 13-28)
The “golden period” for exercise:
- Energy returns
- Less nausea
- Not too big yet
- Best time to establish routine
Modifications needed:
- Avoid lying flat on back after 20 weeks
- Growing belly affects balance
- May need to slow down running/jogging
- Reduce weight lifting intensity
You’ll likely feel great!
Third Trimester (Weeks 29-40)
Exercise becomes more challenging:
- Larger belly affects balance
- Back pain common
- Shortness of breath
- Swelling and discomfort
Focus on:
- Walking
- Swimming (feels weightless!)
- Prenatal yoga
- Stationary cycling
- Pelvic floor exercises
Slow down and modify as needed. Any movement is better than none.
Best Exercises for Pregnancy
Walking
Perfect pregnancy exercise:
- Safe for everyone
- No equipment needed
- Easy to fit into day
- Low impact
- Can do until delivery
Tips:
- Wear supportive shoes
- Stay hydrated
- Avoid overheating
- Walk on flat, even surfaces
- Bring water
Aim for 30 minutes daily – can break into shorter walks.
Swimming and Water Aerobics
Excellent choice:
- Supports your weight
- Reduces joint strain
- Feels refreshing
- Reduces swelling
- Low injury risk
- Can do throughout pregnancy
Water relieves pressure on back and joints – feels amazing in third trimester!
Prenatal Yoga
Benefits:
- Improves flexibility
- Builds strength
- Teaches breathing for labor
- Reduces stress
- Connects you with baby
- Community support
Focus on:
- Modified poses (no lying flat on back)
- Avoid deep twists
- No hot yoga
- Gentle, flowing movements
- Pelvic floor awareness
Take prenatal-specific classes – regular yoga may include unsafe poses.
Stationary Cycling
Safe alternative to outdoor biking:
- No fall risk
- Controlled environment
- Good cardio workout
- Easy to adjust intensity
As pregnancy progresses:
- Raise handlebars for comfort
- Shorter sessions
- Lower resistance
Prenatal Fitness Classes
Designed for pregnancy:
- Safe movements
- Appropriate intensity
- Social support
- Expert guidance
- Confidence you’re doing it right
Look for certified prenatal instructors.
Strength Training
Safe with modifications:
- Use lighter weights
- Focus on form
- Avoid lying flat on back
- Don’t hold breath
- Stop if any pain
Benefits:
- Maintains muscle tone
- Prevents back pain
- Prepares for carrying baby
- Easier postpartum recovery
Essential: Pelvic Floor Exercises (Kegels)
Strengthen muscles that support bladder, uterus, and bowels
Why Kegels Matter
Prevent and treat:
- Urinary incontinence (leaking when coughing/sneezing)
- Support for growing uterus
- Faster postpartum recovery
- Better sex after delivery
- Reduced tearing during delivery
How to Do Kegels
Finding the right muscles:
- Stop urination midstream (that’s the movement)
- Don’t do this regularly (just to identify muscles)
The exercise:
- Squeeze and lift pelvic floor muscles
- Hold for 3-5 seconds
- Release and relax
- Repeat 10-15 times
- Do 3 times daily
Breathe normally – don’t hold breath
Can do anywhere: Sitting, standing, lying down (anytime you remember!)
Deep Belly Breathing
Strengthens core and prepares for labor:
- Sit comfortably
- Breathe deeply into belly (not chest)
- Belly expands on inhale
- Exhale slowly
- Repeat 5-10 times
Combines beautifully with Kegels – exhale as you squeeze, inhale as you relax.
Exercises to Avoid
High Risk of Falling
Don’t do:
- Contact sports (basketball, soccer)
- Horseback riding
- Skiing or snowboarding
- Ice skating
- Surfing
Why: Fall risk and abdominal trauma
Lying Flat on Back (After 20 Weeks)
Avoid exercises that require lying flat:
- Traditional sit-ups or crunches
- Certain yoga poses
- Flat bench press
Why: Heavy uterus compresses major blood vessel, reducing blood flow to baby
Use incline or side-lying positions instead.
High-Impact or Jarring Movements
Be cautious with:
- Jumping
- Bouncing
- Sudden direction changes
- High-impact aerobics
Why: Loosened joints (thanks to relaxin hormone) increase injury risk
Altitude and Scuba Diving
Avoid:
- Scuba diving (any depth)
- High altitude exercise (above 6,000 feet if not accustomed)
Why: Oxygen deprivation risks for baby
Hot Yoga or Exercise in Heat
Avoid:
- Hot yoga (Bikram)
- Exercising in extreme heat
- Saunas and hot tubs
Why: Overheating dangerous to baby, especially first trimester
Warning Signs to Stop Exercise
Stop immediately and call doctor if you experience:
🚨 Vaginal bleeding
🚨 Fluid leaking from vagina (amniotic fluid)
🚨 Regular painful contractions
🚨 Chest pain
🚨 Severe shortness of breath (before exertion)
🚨 Dizziness or faintness
🚨 Severe headache
🚨 Muscle weakness affecting balance
🚨 Calf pain or swelling (may indicate blood clot)
🚨 Decreased fetal movement
These may indicate serious problems. Don’t ignore warning signs.
Normal Discomforts (Usually Safe to Continue)
These are typical:
- Mild breathlessness
- Round ligament pain (sharp pulling in lower belly)
- Braxton Hicks contractions (irregular, stop with rest)
- Mild fatigue
- Normal aches
When in doubt, ask your doctor.
Exercise Safety Tips
Stay Cool
Prevent overheating:
- Exercise in air-conditioned space
- Avoid midday heat
- Wear breathable clothing
- Use fan
- Stop if too hot
Overheating is dangerous especially in first trimester.
Hydrate, Hydrate, Hydrate
Before, during, and after exercise:
- Drink water before starting
- Sip during activity
- Rehydrate afterward
- Urine should be light yellow
Dehydration can trigger contractions.
Eat Properly
Don’t exercise on empty stomach:
- Light snack 30-60 minutes before
- Banana, crackers, yogurt
- Prevents dizziness and low blood sugar
Wear Supportive Gear
Invest in:
- Supportive sports bra (breasts are heavier!)
- Good athletic shoes
- Belly support band (if needed)
- Comfortable, breathable clothes
Warm Up and Cool Down
Always:
- 5 minutes easy movement to warm up
- Gentle stretching after (not before)
- Gradual cool-down
- Never stop abruptly
Listen to Your Body
Pregnancy is not the time to:
- Push through pain
- Set personal records
- Train for competition
- “Bounce back” to pre-pregnancy fitness
Goal is maintaining health, not improving performance.
When Not to Exercise
Some conditions require no exercise:
- Placenta previa (after 26 weeks)
- Risk of preterm labor
- Incompetent cervix or cerclage
- Multiple pregnancy with risk factors
- Severe anemia
- Pregnancy-induced hypertension or pre-eclampsia
- Certain heart or lung conditions
Your doctor will advise if exercise is unsafe for you.
Sample Weekly Exercise Plan
For healthy, low-risk pregnancy:
Monday: 30-minute walk
Tuesday: Prenatal yoga class (45 minutes)
Wednesday: Swimming (30 minutes)
Thursday: Rest or gentle stretching + Kegels
Friday: 30-minute walk or prenatal fitness class
Saturday: Stationary bike (20-30 minutes)
Sunday: Prenatal yoga or rest
Plus: Kegels daily (3 sets throughout day)
Adjust based on how you feel!
Postpartum Exercise
Don’t rush back:
- Vaginal delivery: 4-6 weeks before exercise
- C-section: 6-8 weeks (or when doctor approves)
- Start with walking
- Gradually rebuild core strength
- Focus on pelvic floor first
- Be patient with your body
It took 9 months to grow a baby. Give yourself time to recover.
Remember
Exercise during pregnancy is safe and beneficial for most women. Moving your body helps you feel better, prepares you for labor, and supports a healthy pregnancy.
Listen to your body. Some days you’ll have energy to do more; some days less is best.
Any movement is better than none. Even 10 minutes counts!
You’re growing a human. That’s the biggest workout of all.
