If you have any of the conditions below, do not exercise. Check with your health care provider
- Heart disease
- Lung disease
- Incompetent cervix: The cervix is the narrow, outer end of the uterus. If it is weak, it cannot hold the fetus in the uterus.
- Preterm labor (before 37 completed weeks of pregnancy)
- Multiple pregnancy (twins, triplets or more) at risk for preterm labor
- Frequent bleeding from the vagina during months 4-9 of pregnancy
- Placenta previa: The placenta connects the baby's blood supply to the mother's blood. Attached to the mother's uterus, it is an unborn baby's lifeline. Placenta previa is a low-lying placenta that covers part or all of the cervix. This can block the baby's exit from the uterus.
