Exercise in Pregnancy: How Much Is Safe and What the Research Says

Includes ACOG and WHO guidelines on strength, cardio, and stretching

Introduction

Gone are the days when pregnancy meant total rest. Today, research strongly supports the idea that staying active during pregnancy is not only safe—it’s beneficial. Regular exercise can reduce back pain, improve mood, lower the risk of gestational diabetes, and even shorten labor. But how much exercise is safe? And what types should you focus on?

ACOG and WHO Guidelines at a Glance

ACOG Recommendations (2020)

• At least 150 minutes of moderate-intensity aerobic activity per week
• Spread activity throughout the week
• Most women can continue or modify their pre-pregnancy exercise routines

WHO Recommendations (2020)

• 150 minutes of moderate aerobic activity weekly
• Include muscle-strengthening activities at least twice per week
• Break up prolonged sitting with gentle movement

Types of Exercise: What's Safe?

1. Cardiovascular (Aerobic) Exercise

Examples: Walking, swimming, stationary cycling
Benefits: Supports heart health, stamina, and healthy weight gain

2. Strength Training

Use lighter weights and proper form. Avoid lying flat on your back after the first trimester.
Benefits: Builds muscle, reduces back pain, and supports posture

3. Stretching & Flexibility

Prenatal yoga and Pilates are highly recommended. Avoid deep stretches as ligaments become more relaxed.

Exercises to Avoid

• Contact sports or activities with fall risk (e.g., skiing, soccer, horseback riding)
• Hot yoga or Pilates (risk of overheating)
• Scuba diving
• Lying flat on your back after the first trimester

FAQ: Exercise During Pregnancy

1. Can I start exercising if I wasn’t active before pregnancy?

Yes, as long as you get approval from your doctor. Start with light activities like walking or prenatal yoga and gradually build up.

2. Is it safe to do abdominal exercises while pregnant?

Yes, with modifications. Avoid crunches or planks that cause doming or strain. Focus on core-stabilizing moves and pelvic floor exercises.

3. How do I know if I’m overdoing it?

If you feel dizzy, breathless, nauseated, or experience pain, stop immediately. The “talk test” is a good way to gauge safe intensity.

4. Are there benefits to exercising postpartum?
