No. But for most healthy moms-to-be who do not have any pregnancy-related problems, exercise is a safe and valuable habit. Even so, before exercising during pregnancy talk to your doctor or midwife. She will be able to suggest a fitness plan that is safe for you. Getting a doctor’s advice is important for both women who exercise before pregnancy and for those who’d like to start a fitness routine.

Women with the follow problems may not be able to exercise during pregnancy:

• heart disease
• lung disease
• obesity
• severe diabetes
• thyroid disease
• seizure disorder
• persistent bleeding in the second or third trimester
• complications with past pregnancies
