Dr. Tulika, a Lamaze Childbirth Educator, answers the TOP TEN most commonly asked questions on exercise during pregnancy.

1. Are there any benefits of exercise in pregnancy?
   
   It relieves tension, stress and increases your general strength, improving your ability to carry your large belly. It reduces pregnancy related discomforts such as backache, fatigue, edema (swelling) and increases your self-esteem. Exercise during pregnancy also makes it easier to get back into shape after the baby is born.

   
   

2. When is the best time to begin exercise?
   
   It is best to take permission from your doctor before starting an exercise regimen. Proceed cautiously and avoid overheating as according to some studies, overheating during the first trimester can cause neurological birth defects.

   
   

3. How long should I exercise for?
   
   This varies from person to person. Avoid getting fatigued. If you exercised before pregnancy you should be able to continue with the same exercise, but at an easier pace. Always listen to your body. If you were previously inactive/overweight start with 5 minutes a day and gradually work your way up to 20 minutes over a 2-week period. Consult a Prenatal Exercise Instructor for making a personalized exercise regime that suits your special needs.

   
   

4. Will exercise make birth easier?
   
   Exercise improves your endurance, fitness level and muscle control for a faster, easier and less painful labor: it also strengthens and tones up the pelvic floor muscles.

   
   

5. Can exercise shorten labor?
   
   In a recent study it was discovered that moms who exercise until the last day will have a 30% shorter labor, and about 65% of exercising moms deliver in less than 4 hours.
