The American Congress of Obstetricians and Gynecologists issued an updated set of guidelines for exercise during pregnancy in 2002, suggesting that in the absence of medical or obstetric complications, 30 minutes or more of moderate exercise a day on most, if not all, days of the week is recommended (“patient-friendly version” here). This represented a significant step forward at the time, but as we learn more about both exercise and pregnancy, there are calls to refine these guidelines ever further to define “moderate intensity”, and to develop parameters for strength training and caloric expenditure. In the meantime, the bottom line for nearly all of us is to keep moving (or start moving!)!
