Who should not exercise?
If you have a medical problem, such as asthma, heart disease or diabetes, exercise may not be advisable. Exercise may also be harmful if you have an obstetric condition such as:

• Bleeding or spotting
• Low placenta
• Threatened or recurrent miscarriage
• Previous premature births or history of early labor
• Weak cervix

Talk with your healthcare provider before beginning an exercise program. Your healthcare provider can give you personal exercise guidelines, based on your medical history.
