The following is a summary of the American College of Obstetricians and Gynecologists’ guidelines for exercising while pregnant:
1. In the absence of contraindications (see below), pregnant women are encouraged to engage in 30 minutes or more of moderate exercise a day on most, if not all, days of the week. (See “Don’t Exercise If ...” below.) As always, check with your doctor before beginning an exercise program.
2. During the second and third trimesters, pregnant women should avoid standing motionless for too long and exercising while lying on their backs.
3. A wide range of recreational activities appears to be safe. However, activities with a high risk of falling or abdominal trauma should be avoided; these include basketball, soccer, in-line skating, downhill skiing, horseback riding, ice hockey, gymnastics and vigorous racquet sports.
4. Scuba diving is not safe at any time during pregnancy.
5. Exertion at altitudes of up to 6,000 feet appears safe. However, engaging in physical activities at higher altitudes carries various risks and should be avoided.
