The Nemours Foundation says your doctor should approve any exercise routine while you're pregnant. The foundation says staying fit offers these potential benefits:

• Possible relief from common pregnancy symptoms, such as back pain and constipation.
• Improved sleep.
• Improved physical appearance.
• Helps prepare the body for labor and delivery.
• Helps restore your pre-pregnancy shape and weight a little sooner.
• Improved mood and self-esteem.
